Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Move the VGA arbiter from drivers/gpu to drivers/pci because it's
PCI-specific, not GPU-specific (Bjorn Helgaas)

- Allow controller probe to succeed even when no devices currently
present to allow hot-add later (Fabio Estevam)
- Enable power management on i.MX6QP (Richard Zhu)
- Assert CLKREQ# on i.MX8MM so enumeration doesn't hang when no
device is connected (Richard Zhu)
Marvell Aardvark PCIe controller driver:
- Fix MSI and MSI-X support (Marek Behún, Pali Rohár)
- Add support for ERR and PME interrupts (Pali Rohár)

Feng)
Qualcomm PCIe controller driver:
- Add SM8450 DT binding and driver support (Dmitry Baryshkov)
Renesas R-Car PCIe controller driver:
- Help the controller get to the L1 state since the hardware can't do
it on its own (Marek Vasut)
- Return PCI_ERROR_RESPONSE (~0) for reads that fail on PCIe (Marek
Vasut)
SiFive FU740 PCIe controller driver:
- Drop redundant '-gpios' from DT GPIO lookup (Ben Dooks)

Documentation: Fix duplicate statement about raw_spinlock_t type
Unless it was duplicate on purpose, to emphasize that a raw_spinlock_t
is always a spinning lock regardless of PREEMPT_RT or kernel config,
it's a bit odd that this text is duplicate. So, this patch just clean
it up, keeping the consistency with the other sections of the text.

Kbuild -std=gnu11 updates for v5.18
Linus pointed out the benefits of C99 some years ago, especially variable declarations in loops [1]. At that time, we were not ready for the migration due to old compilers. Recently, Jakob Koschel reported a bug in list_for_each_entry(), which leaks the invalid pointer out of the loop [2]. In the discussion, we agreed that the time had come.

random: treat bootloader trust toggle the same way as cpu trust toggle
If CONFIG_RANDOM_TRUST_CPU is set, the RNG initializes using RDRAND. But, the user can disable (or enable) this behavior by setting `random.trust_cpu=0/1` on the kernel command line. This allows system builders to do reasonable things while avoiding howls from tinfoil hatters. (Or vice versa.) CONFIG_RANDOM_TRUST_BOOTLOADER is basically the same thing, but regards the seed passed via EFI or device tree, which might come from RDRAND or a TPM or somewhere else. In order to allow distros to more easily enable this while avoiding those same howls (or vice versa), this commit adds the corresponding `random.trust_bootloader=0/1` toggle.

tools/vm/page_owner_sort.c: support for user-defined culling rules
When viewing page owner information, we may want to cull blocks of information with our own rules. So it is important to enhance culling function to provide the support for customizing culling rules. Therefore, following adjustments are made: 1. Add --cull option to support the culling of blocks of information with user-defined culling rules. ./page_owner_sort <input> <output> --cull=<rules> ./page_owner_sort <input> <output> --cull <rules> <rules> is a single argument in the form of a comma-separated list to specify individual culling rules, by the sequence of keys k1,k2, .... Mixed use of abbreviated and complete-form of keys is allowed. For reference, please see the document(Documentation/vm/page_owner.rst). Now, assuming two blocks in the input file are as follows: Page allocated via order 0, mask xxxx, pid 1, tgid 1 (task_name_demo) PFN xxxx prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 Page allocated via order 0, mask xxxx, pid 32, tgid 32 (task_name_demo) PFN xxxx prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 If we want to cull the blocks by stacktrace and task command name, we can use this command: ./page_owner_sort <input> <output> --cull=stacktrace,name The output would be like: 2 times, 2 pages, task_comm_name: task_name_demo prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 As we can see, these two blocks are culled successfully, for they share the same pid and task command name. However, if we want to cull the blocks by pid, stacktrace and task command name, we can this command: ./page_owner_sort <input> <output> --cull=stacktrace,name,pid The output would be like: 1 times, 1 pages, PID 1, task_comm_name: task_name_demo prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 1 times, 1 pages, PID 32, task_comm_name: task_name_demo prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 As we can see, these two blocks are failed to cull, for their PIDs are different. 2. Add explanations of --cull options to the document.

tools/vm/page_owner_sort.c: support for selecting by PID, TGID or task command name
When viewing page owner information, we may also need to select the blocks by PID, TGID or task command name, which helps to get more accurate page allocation information as needed. Therefore, following adjustments are made: 1. Add three new options, including --pid, --tgid and --name, to support the selection of information blocks by a specific pid, tgid and task command name. In addtion, multiple options are allowed to be used at the same time. ./page_owner_sort [input] [output] --pid <PID> ./page_owner_sort [input] [output] --tgid <TGID> ./page_owner_sort [input] [output] --name <TASK_COMMAND_NAME> Assuming a scenario when a multi-threaded program, ./demo (PID = 5280), is running, and ./demo creates a child process (PID = 5281). $ps PID TTY TIME CMD 5215 pts/0 00:00:00 bash 5280 pts/0 00:00:00 ./demo 5281 pts/0 00:00:00 ./demo 5282 pts/0 00:00:00 ps It would be better to filter out the records with tgid=5280 and the task name "demo" when debugging the parent process, and the specific usage is ./page_owner_sort [input] [output] --tgid 5280 --name demo 2. Add explanations of three new options, including --pid, --tgid and --name, to the document.

tools/vm/page_owner_sort.c: support sorting by tgid and update documentation
When the "page owner" information is read, the information sorted by TGID is expected. As a result, the following adjustments have been made: 1. Add a new -P option to sort the information of blocks by TGID in ascending order. 2. Adjust the order of member variables in block_list strust to avoid one 4 byte hole. 3. Add -P option explanation in the document.

tools/vm/page_owner_sort.c: fix comments
Two adjustments are made:
1. Correct a grammatical error: replace the "what" in "Do the job what
you want to debug" with "that".
2. Replace "has not been" with "has been" in the description of the -f
option: According to Commit b1c9ba071e7d ("tools/vm/page_owner_sort.c:
fix the instructions for use"), the description of the "-f" option is
"Filter out the information of blocks whose memory has been released."

cxl for 5.18
- Add a driver for 'struct cxl_memdev' objects responsible for CXL.mem
operation as distinct from 'cxl_pci' mailbox operations. Its primary
responsibility is enumerating an endpoint 'struct cxl_port' and all the
'struct cxl_port' instances between an endpoint and the CXL platform
root.
- Add a driver for 'struct cxl_port' objects responsible for enumerating
and operating all Host-managed Device Memory (HDM) decoder resources
between the platform-level CXL memory description, all intervening host
bridges / switches, and the HDM resources in endpoints.
- Update the cxl_pci driver to validate CXL.mem operation precursors to
HDM decoder operation like ready-polling, and legacy CXL 1.1 DVSEC
based CXL.mem configuration.
- Add basic lockdep coverage for usage of device_lock() on CXL subsystem
objects similar to what exists for LIBNVDIMM. Include a compile-time
switch for which subsystem to validate at run-time.
- Update cxl_test to emulate a one level switch topology.
- Document a "Theory of Operation" for the subsystem.
- Add 'numa_node' and 'serial' attributes to cxl_memdev sysfs
- Include miscellaneous fixes for spec / QEMU CXL emulation
compatibility and static analysis reports.

Pull CXL (Compute Express Link) updates from Dan Williams:
"This development cycle extends the subsystem to discover CXL resources
throughout a CXL/PCIe switch topology and respond to hot add/remove
events anywhere in that topology.
This is more foundational infrastructure in preparation for dynamic
memory region provisioning support. Recall that CXL memory regions, as
the new "Theory of Operation" section of
Documentation/driver-api/cxl/memory-devices.rst describes, bring
storage volume striping semantics to memory.
The hot add/remove behavior is validated with extensions to the
cxl_test unit test environment and this test in the cxl-cli test
suite:

Networking changes for 5.18.
Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout
the stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower
iTLB pressure and prevents identity mapping huge pages from
getting split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop
the user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if called
from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling
of TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

panic: move panic_print before kmsg dumpers
The panic_print setting allows users to collect more information in a
panic event, like memory stats, tasks, CPUs backtraces, etc. This is an
interesting debug mechanism, but currently the print event happens *after*
kmsg_dump(), meaning that pstore, for example, cannot collect a dmesg with
the panic_print extra information.
This patch changes that in 2 steps:
(a) The panic_print setting allows to replay the existing kernel log
buffer to the console (bit 5), besides the extra information dump.
This functionality makes sense only at the end of the panic()
function. So, we hereby allow to distinguish the two situations by a
new boolean parameter in the function panic_print_sys_info().
(b) With the above change, we can safely call panic_print_sys_info()
before kmsg_dump(), allowing to dump the extra information when using
pstore or other kmsg dumpers.
The additional messages from panic_print could overwrite the oldest
messages when the buffer is full. The only reasonable solution is to use
a large enough log buffer, hence we added an advice into the kernel
parameters documentation about that.

panic: add option to dump all CPUs backtraces in panic_print
Currently the "panic_print" parameter/sysctl allows some interesting debug information to be printed during a panic event. This is useful for example in cases the user cannot kdump due to resource limits, or if the user collects panic logs in a serial output (or pstore) and prefers a fast reboot instead of a kdump. Happens that currently there's no way to see all CPUs backtraces in a panic using "panic_print" on architectures that support that. We do have "oops_all_cpu_backtrace" sysctl, but although partially overlapping in the functionality, they are orthogonal in nature: "panic_print" is a panic tuning (and we have panics without oopses, like direct calls to panic() or maybe other paths that don't go through oops_enter() function), and the original purpose of "oops_all_cpu_backtrace" is to provide more information on oopses for cases in which the users desire to continue running the kernel even after an oops, i.e., used in non-panic scenarios. So, we hereby introduce an additional bit for "panic_print" to allow dumping the CPUs backtraces during a panic event.

ARM: DT updates for 5.18
After a somewhat quiet 5.17 release, the size of the DT changes
is a bit larger again. There are nine new SoC that get added,
all of them related to existing platforms:

over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91, Allwinner,
i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.
A few more platforms only have smaller cleanups and DT Schema fixes,
this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.

ARM driver updates for 5.18
There are a few separately maintained driver subsystems that we merge through
the SoC tree, notable changes are:
- Memory controller updates, mainly for Tegra and Mediatek SoCs,
and clarifications for the memory controller DT bindings
- SCMI firmware interface updates, in particular a new transport based
on OPTEE and support for atomic operations.
- Cleanups to the TEE subsystem, refactoring its memory management
For SoC specific drivers without a separate subsystem, changes include
- Smaller updates and fixes for TI, AT91/SAMA5, Qualcomm and NXP
Layerscape SoCs.
- Driver support for Microchip SAMA5D29, Tesla FSD, Renesas RZ/G2L,
and Qualcomm SM8450.
- Better power management on Mediatek MT81xx, NXP i.MX8MQ
and older NVIDIA Tegra chips

ARM: SoC updates for 5.18
SoC specific code is generally used for older platforms that don't (yet)
use device tree to do the same things.
- Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller
from NXP. At the moment this is still incomplete as other portions
are merged through different trees.
- Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
gets removed, now the Arm NOMMU platforms are limited to the
Cortex-M family of microcontrollers
- Two old PXA boards get removed, along with corresponding driver
bits.
- Continued cleanup of the Intel IXP4xx platforms, removing some
remnants of the old board files.
- Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung
- CPU idle support for AT91
- A system controller driver for Polarfire

Pull ARM SoC updates from Arnd Bergmann:
"SoC specific code is generally used for older platforms that don't
(yet) use device tree to do the same things.
- Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller
from NXP. At the moment this is still incomplete as other portions
are merged through different trees.
- Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
gets removed, now the Arm NOMMU platforms are limited to the
Cortex-M family of microcontrollers
- Two old PXA boards get removed, along with corresponding driver
bits.
- Continued cleanup of the Intel IXP4xx platforms, removing some
remnants of the old board files.
- Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung
- CPU idle support for AT91
- A system controller driver for Polarfire"

asm-generic updates for 5.18
There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

dt-bindings: kbuild: Make DT_SCHEMA_LINT a recursive variable
A recent change added a warning when yamllint is not installed, as it is
needed for 'make dt_binding_check'. However, it also changed
DT_SCHEMA_LINT to be a simple make variable, which is evaluated when a
Makefile is evaluated. This causes a warning when running 'make clean',
as Documentation/devicetree/bindings/Makefile has a "clean-files"
variable:
$ make -s clean
which: no yamllint in (...)
warning: python package 'yamllint' not installed, skipping
Make DT_SCHEMA_LINT a recursive variable so it is evaluated only when it
is used. The warning still triggers when 'make dt_binding_check' is run.

dt-bindings: nvmem: add U-Boot environment variables binding
U-Boot uses environment variables for storing device setup data. It usually needs to be accessed by a bootloader, kernel and often user-space. This binding allows describing environment data located in a raw flash partition. It's treated as NVMEM device and can be reused later for other storage devices. Using DT should be cleaner than hardcoding & duplicating such info in multiple places. Bootloader & kernel can share DTS and user-space can try reading it too or just have correct data exposed by a kernel. A custom "compatible" string allows system to automatically load relevant NVMEM driver but phandle can be also used for reading raw location.

Tracing updates for 5.18:
- New user_events interface. User space can register an event with the kernel describing the format of the event. Then it will receive a byte in a page mapping that it can check against. A privileged task can then enable that event like any other event, which will change the mapped byte to true, telling the user space application to start writing the event to the tracing buffer. - Add new "ftrace_boot_snapshot" kernel command line parameter. When set, the tracing buffer will be saved in the snapshot buffer at boot up when the kernel hands things over to user space. This will keep the traces that happened at boot up available even if user space boot up has tracing as well. - Have TRACE_EVENT_ENUM() also update trace event field type descriptions. Thus if a static array defines its size with an enum, the user space trace event parsers can still know how to parse that array. - Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the TRACE_EVENT() macro, but will attach to an existing tracepoint. This will make one tracepoint be able to trace different content and not be stuck at only what the original TRACE_EVENT() macro exports. - Fixes to tracing error logging. - Better saving of cmdlines to PIDs when tracing (use the wakeup events for mapping). -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYjiO3RQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qhQzAQDtek5p80p/zkMGymm14wSH6qq0NdgN Kv7fTBwEewUa0gD/UCOVLw4Oj+JtHQhCa3sCGZopmRv0BT1+4UQANqosKQY= =Au08 -----END PGP SIGNATURE----- Merge tag 'trace-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - New user_events interface.

Filesystem folio changes for 5.18
Primarily this series converts some of the address_space operations
to take a folio instead of a page.
->is_partially_uptodate() takes a folio instead of a page and changes the
type of the 'from' and 'count' arguments to make it obvious they're bytes.
->invalidatepage() becomes ->invalidate_folio() and has a similar type change.
->launder_page() becomes ->launder_folio()
->set_page_dirty() becomes ->dirty_folio() and adds the address_space as
an argument.
There are a couple of other misc changes up front that weren't worth
separating into their own pull request.

Docs/vm/damon/design: update DAMON-Idle Page Tracking interference handling
In DAMON's early development stage before it be merged in the mainline, it was first designed to work exclusively with Idle page tracking to avoid any interference between each other. Later, but still before be merged in the mainline, because Idle page tracking is fully under the control of sysadmins, we made the resolving of conflict as the responsibility of sysadmins. The document is not updated for the change, though. This commit updates the document for that.

Docs/vm/damon: call low level monitoring primitives the operations
Patch series "Docs/damon: Update documents for better consistency". Some of DAMON document are not properly updated for latest version. This patchset updates such parts. This patch (of 3): DAMON code calls the low level monitoring primitives implementations the monitoring operations. The documentation would have no problem at still calling those primitives implementation because there is no real difference in the concepts, but making it more consistent with the code would make it better. This commit therefore convert sentences in the doc specifically pointing the implementations of the primitives to call it monitoring operations.

kfence: allow use of a deferrable timer
Allow the use of a deferrable timer, which does not force CPU wake-ups when the system is idle. A consequence is that the sample interval becomes very unpredictable, to the point that it is not guaranteed that the KFENCE KUnit test still passes. Nevertheless, on power-constrained systems this may be preferable, so let's give the user the option should they accept the above trade-off.

mm/zswap.c: allow handling just same-value filled pages
Zswap has an ability to efficiently store same-value filled pages, which can be turned on and off using the "same_filled_pages_enabled" parameter. However, there is currently no way to enable just this (lightweight) functionality, while not making use of the whole compressed page storage machinery. Add a "non_same_filled_pages_enabled" parameter which allows disabling handling of pages that aren't same-value filled. This way zswap can be run in such lightweight same-value filled pages only mode.

NUMA balancing: optimize page placement for memory tiering system
With the advent of various new memory types, some machines will have multiple types of memory, e.g. DRAM and PMEM (persistent memory). The memory subsystem of these machines can be called memory tiering system, because the performance of the different types of memory are usually different. In such system, because of the memory accessing pattern changing etc, some pages in the slow memory may become hot globally. So in this patch, the NUMA balancing mechanism is enhanced to optimize the page placement among the different memory types according to hot/cold dynamically. In a typical memory tiering system, there are CPUs, fast memory and slow memory in each physical NUMA node. The CPUs and the fast memory will be put in one logical node (called fast memory node), while the slow memory will be put in another (faked) logical node (called slow memory node). That is, the fast memory is regarded as local while the slow memory is regarded as remote. So it's possible for the recently accessed pages in the slow memory node to be promoted to the fast memory node via the existing NUMA balancing mechanism. The original NUMA balancing mechanism will stop to migrate pages if the free memory of the target node becomes below the high watermark. This is a reasonable policy if there's only one memory type. But this makes the original NUMA balancing mechanism almost do not work to optimize page placement among different memory types. Details are as follows. It's the common cases that the working-set size of the workload is larger than the size of the fast memory nodes. Otherwise, it's unnecessary to use the slow memory at all. So, there are almost always no enough free pages in the fast memory nodes, so that the globally hot pages in the slow memory node cannot be promoted to the fast memory node. To solve the issue, we have 2 choices as follows, a. Ignore the free pages watermark checking when promoting hot pages from the slow memory node to the fast memory node. This will create some memory pressure in the fast memory node, thus trigger the memory reclaiming. So that, the cold pages in the fast memory node will be demoted to the slow memory node. b. Define a new watermark called wmark_promo which is higher than wmark_high, and have kswapd reclaiming pages until free pages reach such watermark. The scenario is as follows: when we want to promote hot-pages from a slow memory to a fast memory, but fast memory's free pages would go lower than high watermark with such promotion, we wake up kswapd with wmark_promo watermark in order to demote cold pages and free us up some space. So, next time we want to promote hot-pages we might have a chance of doing so. The choice "a" may create high memory pressure in the fast memory node. If the memory pressure of the workload is high, the memory pressure may become so high that the memory allocation latency of the workload is influenced, e.g. the direct reclaiming may be triggered. The choice "b" works much better at this aspect. If the memory pressure of the workload is high, the hot pages promotion will stop earlier because its allocation watermark is higher than that of the normal memory allocation. So in this patch, choice "b" is implemented. A new zone watermark (WMARK_PROMO) is added. Which is larger than the high watermark and can be controlled via watermark_scale_factor. In addition to the original page placement optimization among sockets, the NUMA balancing mechanism is extended to be used to optimize page placement according to hot/cold among different memory types. So the sysctl user space interface (numa_balancing) is extended in a backward compatible way as follow, so that the users can enable/disable these functionality individually. The sysctl is converted from a Boolean value to a bits field. The definition of the flags is, - 0: NUMA_BALANCING_DISABLED - 1: NUMA_BALANCING_NORMAL - 2: NUMA_BALANCING_MEMORY_TIERING We have tested the patch with the pmbench memory accessing benchmark with the 80:20 read/write ratio and the Gauss access address distribution on a 2 socket Intel server with Optane DC Persistent Memory Model. The test results shows that the pmbench score can improve up to 95.9%. Thanks Andrew Morton to help fix the document format error.

mm: hugetlb: free the 2nd vmemmap page associated with each HugeTLB page
Patch series "Free the 2nd vmemmap page associated with each HugeTLB
page", v7.
This series can minimize the overhead of struct page for 2MB HugeTLB
pages significantly. It further reduces the overhead of struct page by
12.5% for a 2MB HugeTLB compared to the previous approach, which means
2GB per 1TB HugeTLB. It is a nice gain. Comments and reviews are
welcome. Thanks.
The main implementation and details can refer to the commit log of patch
1. In this series, I have changed the following four helpers, the
following table shows the impact of the overhead of those helpers.
+------------------+-----------------------+
| APIs | head page | tail page |
+------------------+-----------+-----------+
| PageHead() | Y | N |
+------------------+-----------+-----------+
| PageTail() | Y | N |
+------------------+-----------+-----------+
| PageCompound() | N | N |
+------------------+-----------+-----------+
| compound_head() | Y | N |
+------------------+-----------+-----------+
Y: Overhead is increased.
N: Overhead is _NOT_ increased.
It shows that the overhead of those helpers on a tail page don't change
between "hugetlb_free_vmemmap=on" and "hugetlb_free_vmemmap=off". But the
overhead on a head page will be increased when "hugetlb_free_vmemmap=on"
(except PageCompound()). So I believe that Matthew Wilcox's folio series
will help with this.
The users of PageHead() and PageTail() are much less than compound_head()
and most users of PageTail() are VM_BUG_ON(), so I have done some tests
about the overhead of compound_head() on head pages.
I have tested the overhead of calling compound_head() on a head page,
which is 2.11ns (Measure the call time of 10 million times
compound_head(), and then average).
For a head page whose address is not aligned with PAGE_SIZE or a
non-compound page, the overhead of compound_head() is 2.54ns which is
increased by 20%. For a head page whose address is aligned with
PAGE_SIZE, the overhead of compound_head() is 2.97ns which is increased by
40%. Most pages are the former. I do not think the overhead is
significant since the overhead of compound_head() itself is low.
This patch (of 5):
This patch minimizes the overhead of struct page for 2MB HugeTLB pages
significantly. It further reduces the overhead of struct page by 12.5%
for a 2MB HugeTLB compared to the previous approach, which means 2GB per
1TB HugeTLB (2MB type).
After the feature of "Free sonme vmemmap pages of HugeTLB page" is
enabled, the mapping of the vmemmap addresses associated with a 2MB
HugeTLB page becomes the figure below.
HugeTLB struct pages(8 pages) page frame(8 pages)
+-----------+ ---virt_to_page---> +-----------+ mapping to +-----------+---> PG_head
| | | 0 | -------------> | 0 |
| | +-----------+ +-----------+
| | | 1 | -------------> | 1 |
| | +-----------+ +-----------+
| | | 2 | ----------------^ ^ ^ ^ ^ ^
| | +-----------+ | | | | |
| | | 3 | ------------------+ | | | |
| | +-----------+ | | | |
| | | 4 | --------------------+ | | |
| 2MB | +-----------+ | | |
| | | 5 | ----------------------+ | |
| | +-----------+ | |
| | | 6 | ------------------------+ |
| | +-----------+ |
| | | 7 | --------------------------+
| | +-----------+
| |
| |
| |
+-----------+
As we can see, the 2nd vmemmap page frame (indexed by 1) is reused and
remaped. However, the 2nd vmemmap page frame is also can be freed to
the buddy allocator, then we can change the mapping from the figure
above to the figure below.
HugeTLB struct pages(8 pages) page frame(8 pages)
+-----------+ ---virt_to_page---> +-----------+ mapping to +-----------+---> PG_head
| | | 0 | -------------> | 0 |
| | +-----------+ +-----------+
| | | 1 | ---------------^ ^ ^ ^ ^ ^ ^
| | +-----------+ | | | | | |
| | | 2 | -----------------+ | | | | |
| | +-----------+ | | | | |
| | | 3 | -------------------+ | | | |
| | +-----------+ | | | |
| | | 4 | ---------------------+ | | |
| 2MB | +-----------+ | | |
| | | 5 | -----------------------+ | |
| | +-----------+ | |
| | | 6 | -------------------------+ |
| | +-----------+ |
| | | 7 | ---------------------------+
| | +-----------+
| |
| |
| |
+-----------+
After we do this, all tail vmemmap pages (1-7) are mapped to the head
vmemmap page frame (0). In other words, there are more than one page
struct with PG_head associated with each HugeTLB page. We __know__ that
there is only one head page struct, the tail page structs with PG_head are
fake head page structs. We need an approach to distinguish between those
two different types of page structs so that compound_head(), PageHead()
and PageTail() can work properly if the parameter is the tail page struct
but with PG_head.
The following code snippet describes how to distinguish between real and
fake head page struct.
if (test_bit(PG_head, &page->flags)) {
unsigned long head = READ_ONCE(page[1].compound_head);
if (head & 1) {
if (head == (unsigned long)page + 1)
==> head page struct
else
==> tail page struct
} else
==> head page struct
}
We can safely access the field of the @page[1] with PG_head because the
@page is a compound page composed with at least two contiguous pages.

fs: introduce alloc_inode_sb() to allocate filesystems specific inode
The allocated inode cache is supposed to be added to its memcg list_lru which should be allocated as well in advance. That can be done by kmem_cache_alloc_lru() which allocates object and list_lru. The file systems is main user of it. So introduce alloc_inode_sb() to allocate file system specific inodes and set up the inode reclaim context properly. The file system is supposed to use alloc_inode_sb() to allocate inodes. In later patches, we will convert all users to the new API.

mm/memcg: disable threshold event handlers on PREEMPT_RT
During the integration of PREEMPT_RT support, the code flow around memcg_check_events() resulted in `twisted code'. Moving the code around and avoiding then would then lead to an additional local-irq-save section within memcg_check_events(). While looking better, it adds a local-irq-save section to code flow which is usually within an local-irq-off block on non-PREEMPT_RT configurations. The threshold event handler is a deprecated memcg v1 feature. Instead of trying to get it to work under PREEMPT_RT just disable it. There should be no users on PREEMPT_RT. From that perspective it makes even less sense to get it to work under PREEMPT_RT while having zero users. Make memory.soft_limit_in_bytes and cgroup.event_control return -EOPNOTSUPP on PREEMPT_RT. Make an empty memcg_check_events() and memcg_write_event_control() which return only -EOPNOTSUPP on PREEMPT_RT. Document that the two knobs are disabled on PREEMPT_RT.

memcg: add per-memcg total kernel memory stat
Currently memcg stats show several types of kernel memory: kernel stack, page tables, sock, vmalloc, and slab. However, there are other allocations with __GFP_ACCOUNT (or supersets such as GFP_KERNEL_ACCOUNT) that are not accounted in any of those stats, a few examples are: - various kvm allocations (e.g. allocated pages to create vcpus) - io_uring - tmp_page in pipes during pipe_write() - bpf ringbuffers - unix sockets Keeping track of the total kernel memory is essential for the ease of migration from cgroup v1 to v2 as there are large discrepancies between v1's kmem.usage_in_bytes and the sum of the available kernel memory stats in v2. Adding separate memcg stats for all __GFP_ACCOUNT kernel allocations is an impractical maintenance burden as there a lot of those all over the kernel code, with more use cases likely to show up in the future. Therefore, add a "kernel" memcg stat that is analogous to kmem page counter, with added benefits such as using rstat infrastructure which aggregates stats more efficiently. Additionally, this provides a lighter alternative in case the legacy kmem is deprecated in the future [yosryahmed@google.com: v2] Link: https://lkml.kernel.org/r/20220203193856.972500-1-yosryahmed@google.com Link: https://lkml.kernel.org/r/20220201200823.3283171-1-yosryahmed@google.com Signed-off-by: Yosry Ahmed <yosryahmed@google.com> Acked-by: Shakeel Butt <shakeelb@google.com> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: Michal Hocko <mhocko@kernel.org> Cc: Muchun Song <songmuchun@bytedance.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

mm: document and polish read-ahead code
Add some "big-picture" documentation for read-ahead and polish the code to make it fit this documentation. The meaning of ->async_size is clarified to match its name. i.e. Any request to ->readahead() has a sync part and an async part. The caller will wait for the sync pages to complete, but will not wait for the async pages. The first async page is still marked PG_readahead Note that the current function names page_cache_sync_ra() and page_cache_async_ra() are misleading. All ra request are partly sync and partly async, so either part can be empty. A page_cache_sync_ra() request will usually set ->async_size non-zero, implying it is not all synchronous. When a non-zero req_count is passed to page_cache_async_ra(), the implication is that some prefix of the request is synchronous, though the calculation made there is incorrect - I haven't tried to fix it.

Changes in this cycle were:
- Cleanups for SCHED_DEADLINE
- Tracing updates/fixes
- CPU Accounting fixes
- First wave of changes to optimize the overhead of the scheduler build,
from the fast-headers tree - including placeholder *_api.h headers for
later header split-ups.
- Preempt-dynamic using static_branch() for ARM64
- Isolation housekeeping mask rework; preperatory for further changes
- NUMA-balancing: deal with CPU-less nodes
- NUMA-balancing: tune systems that have multiple LLC cache domains per node (eg. AMD)

ALSA: hda/realtek: Add alc256-samsung-headphone fixup
This fixes the near-silence of the headphone jack on the ALC256-based Samsung Galaxy Book Flex Alpha (NP730QCJ). The magic verbs were found through trial and error, using known ALC298 hacks as inspiration. The fixup is auto-enabled only when the NP730QCJ is detected. It can be manually enabled using model=alc256-samsung-headphone.

f2fs-for-5.18
In this cycle, f2fs has some performance improvements for Android workloads such
as using read-unfair rwsems and adding some sysfs entries to control GCs and
discard commands in more details. In addtiion, it has some tunings to improve
the recovery speed after sudden power-cut.
Enhancement:
- add reader-unfair rwsems with F2FS_UNFAIR_RWSEM
: will replace with generic API support
- adjust to make the readahead/recovery flow more efficiently
- sysfs entries to control issue speeds of GCs and Discard commands
- enable idmapped mounts
Bug fix:
- correct wrong error handling routines
- fix missing conditions in quota
- fix a potential deadlock between writeback and block plug routines
- fix a deadlock btween freezefs and evict_inode
We've added some boundary checks to avoid kernel panics on corrupted images,
and several minor code clean-ups.

remaining uncompressed paths to prepare for the upcoming subpage,
folio and fscache features.
We also fixed a double-free issue when sysfs initialization fails,
which was reported by syzbot.
Besides, in order for the userspace to control per-file timestamp
easier, we now switch to record mtime instead of ctime with a
compatible feature marked. And there are also some code cleanups and
documentation update as usual.

Pull selinux updates from Paul Moore:
"We've got a number of SELinux patches queued up, the highlights are:
- Fixup the security_fs_context_parse_param() LSM hook so it executes
all of the LSM hook implementations unless a serious error occurs.
We also correct the SELinux hook implementation so that it returns
zero on success.
- In addition to a few SELinux mount option parsing fixes, we
simplified the parsing by moving it earlier in the process.
The logic was that it was unlikely an admin/user would use the new
mount API and not have the policy loaded before passing the SELinux
options.
- Properly fixed the LSM/SELinux/SCTP hooks with the addition of the
security_sctp_assoc_established() hook.
This work was done in conjunction with the netdev folks and should
complete the move of the SCTP labeling from the endpoints to the
associations.
- Fixed a variety of sparse warnings caused by changes in the "__rcu"
markings of some core kernel structures.
- Ensure we access the superblock's LSM security blob using the
stacking-safe accessors.
- Added the ability for the kernel to always allow FIOCLEX and
FIONCLEX if the "ioctl_skip_cloexec" policy capability is
specified.
- Various constifications improvements, type casting improvements,
additional return value checks, and dead code/parameter removal.
- Documentation fixes"

spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from
the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
Sunplus SP7021.

Pull random number generator updates from Jason Donenfeld:
"There have been a few important changes to the RNG's crypto, but the
intent for 5.18 has been to shore up the existing design as much as
possible with modern cryptographic functions and proven constructions,
rather than actually changing up anything fundamental to the RNG's
design.
So it's still the same old RNG at its core as before: it still counts
entropy bits, and collects from the various sources with the same
heuristics as before, and so forth. However, the cryptographic
algorithms that transform that entropic data into safe random numbers
have been modernized.
Just as important, if not more, is that the code has been cleaned up
and re-documented. As one of the first drivers in Linux, going back to
1.3.30, its general style and organization was showing its age and
becoming both a maintenance burden and an auditability impediment.
Hopefully this provides a more solid foundation to build on for the
future. I encourage you to open up the file in full, and maybe you'll
remark, "oh, that's what it's doing," and enjoy reading it. That, at
least, is the eventual goal, which this pull begins working toward.
Here's a summary of the various patches in this pull:
- /dev/urandom and /dev/random now do the same thing, per the patch
we discussed on the list. I think this is worth trying out. If it
does appear problematic, I've made sure to keep it standalone and
revertible without any conflicts.
- Fixes and cleanups for numerous integer type problems, locking
issues, and general code quality concerns.
- The input pool's LFSR has been replaced with a cryptographically
secure hash function, which has security and performance benefits
alike, and consequently allows us to count entropy bits linearly.
- The pre-init injection now uses a real hash function too, instead
of an LFSR or vanilla xor.
- The interrupt handler's fast_mix() function now uses one round of
SipHash, rather than the fake crypto that was there before.
- All additions of RDRAND and RDSEED now go through the input pool's
hash function, in part to mitigate ridiculous hypothetical CPU
backdoors, but more so to have a consistent interface for ingesting
entropy that's easy to analyze, making everything happen one way,
instead of a potpourri of different ways.
- The crng now works on per-cpu data, while also being in accordance
with the actual "fast key erasure RNG" design. This allows us to
fix several boot-time race complications associated with the prior
dynamically allocated model, eliminates much locking, and makes our
backtrack protection more robust.
- Batched entropy now erases doled out values so that it's backtrack
resistant.
- Working closely with Sebastian, the interrupt handler no longer
needs to take any locks at all, as we punt the
synchronized/expensive operations to a workqueue. This is
especially nice for PREEMPT_RT, where taking spinlocks in irq
context is problematic. It also makes the handler faster for the
rest of us.
- Also working with Sebastian, we now do the right thing on CPU
hotplug, so that we don't use stale entropy or fail to accumulate
new entropy when CPUs come back online.
- We handle virtual machines that fork / clone / snapshot, using the
"vmgenid" ACPI specification for retrieving a unique new RNG seed,
which we can use to also make WireGuard (and in the future, other
things) safe across VM forks.
- Around boot time, we now try to reseed more often if enough entropy
is available, before settling on the usual 5 minute schedule.
- Last, but certainly not least, the documentation in the file has
been updated considerably"

Pull power management updates from Rafael Wysocki:
"These are mostly fixes and cleanups all over the code and a new piece
of documentation for Intel uncore frequency scaling.
Functionality-wise, the intel_idle driver will support Sapphire Rapids
Xeons natively now (with some extra facilities for controlling
C-states more precisely on those systems), virtual guests will take
the ACPI S4 hardware signature into account by default, the
intel_pstate driver will take the defualt EPP value from the firmware,
cpupower utility will support the AMD P-state driver added in the
previous cycle, and there is a new tracer utility for that driver.
Specifics:
- Allow device_pm_check_callbacks() to be called from interrupt
context without issues (Dmitry Baryshkov).
- Modify devm_pm_runtime_enable() to automatically handle
pm_runtime_dont_use_autosuspend() at driver exit time (Douglas
Anderson).
- Make the schedutil cpufreq governor use to_gov_attr_set() instead
of open coding it (Kevin Hao).
- Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
cpufreq longhaul driver (Rafael Wysocki).
- Unify show() and store() naming in cpufreq and make it use
__ATTR_XX (Lianjie Zhang).
- Make the intel_pstate driver use the EPP value set by the firmware
by default (Srinivas Pandruvada).
- Re-order the init checks in the powernow-k8 cpufreq driver (Mario
Limonciello).
- Make the ACPI processor idle driver check for architectural support
for LPI to avoid using it on x86 by mistake (Mario Limonciello).
- Add Sapphire Rapids Xeon support to the intel_idle driver (Artem
Bityutskiy).
- Add 'preferred_cstates' module argument to the intel_idle driver to
work around C1 and C1E handling issue on Sapphire Rapids (Artem
Bityutskiy).
- Add core C6 optimization on Sapphire Rapids to the intel_idle
driver (Artem Bityutskiy).
- Optimize the haltpoll cpuidle driver a bit (Li RongQing).
- Remove leftover text from intel_idle() kerneldoc comment and fix up
white space in intel_idle (Rafael Wysocki).
- Fix load_image_and_restore() error path (Ye Bin).
- Fix typos in comments in the system wakeup hadling code (Tom Rix).
- Clean up non-kernel-doc comments in hibernation code (Jiapeng
Chong).
- Fix __setup handler error handling in system-wide suspend and
hibernation core code (Randy Dunlap).
- Add device name to suspend_report_result() (Youngjin Jang).
- Make virtual guests honour ACPI S4 hardware signature by default
(David Woodhouse).
- Block power off of a parent PM domain unless child is in deepest
state (Ulf Hansson).
- Use dev_err_probe() to simplify error handling for generic PM
domains (Ahmad Fatoum).
- Fix sleep-in-atomic bug caused by genpd_debug_remove() (Shawn Guo).
- Document Intel uncore frequency scaling (Srinivas Pandruvada).
- Add DTPM hierarchy description (Daniel Lezcano).
- Change the locking scheme in DTPM (Daniel Lezcano).
- Fix dtpm_cpu cleanup at exit time and missing virtual DTPM pointer
release (Daniel Lezcano).
- Make dtpm_node_callback[] static (kernel test robot).
- Fix spelling mistake "initialze" -> "initialize" in
dtpm_create_hierarchy() (Colin Ian King).
- Add tracer tool for the amd-pstate driver (Jinzhou Su).
- Fix PC6 displaying in turbostat on some systems (Artem Bityutskiy).
- Add AMD P-State support to the cpupower utility (Huang Rui)"

Pull ACPI updates from Rafael Wysocki:
"From the new functionality perspective, the most significant items
here are the new driver for the 'ARM Generic Diagnostic Dump and
Reset' device, the extension of fine grain fan control in the ACPI fan
driver, and the change making it possible to use CPPC information to
obtain CPU capacity.
There are also a few new quirks, a bunch of fixes, including the
platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration
documentation.

Timers and timekeeping updates:
Core code:
- Make the NOHZ handling of the timekeeping/tick core more robust to
prevent a rare jiffies update stall.
- Handle softirqs in the NOHZ/idle case correctly
Drivers:
- Add support for event stream scaling of the 1GHz counter on ARM(64)
- Correct an error code check in the timer-of layer
- The usual cleanups and improvements all over the place

Reenable ENQCMD/PASID support:
- Simplify the PASID handling to allocate the PASID once, associate it to
the mm of a process and free it on mm_exit(). The previous attempt of
refcounted PASIDs and dynamic alloc()/free() turned out to be error
prone and too complex. The PASID space is 20bits, so the case of
resource exhaustion is a pure academic concern.
- Populate the PASID MSR on demand via #GP to avoid racy updates via IPIs.
- Reenable ENQCMD and let objtool check for the forbidden usage of ENQCMD
in the kernel.
- Update the documentation for Shared Virtual Addressing accordingly.

mm: Make compound_pincount always available
Move compound_pincount from the third page to the second page, which means it's available for all compound pages. That lets us delete hpage_pincount_available(). On 32-bit systems, there isn't enough space for both compound_pincount and compound_nr in the second page (it would collide with page->private, which is in use for pages in the swap cache), so revert the optimisation of storing both compound_order and compound_nr on 32-bit systems.

KVM: x86: Introduce KVM_CAP_DISABLE_QUIRKS2
KVM_CAP_DISABLE_QUIRKS is irrevocably broken. The capability does not advertise the set of quirks which may be disabled to userspace, so it is impossible to predict the behavior of KVM. Worse yet, KVM_CAP_DISABLE_QUIRKS will tolerate any value for cap->args[0], meaning it fails to reject attempts to set invalid quirk bits. The only valid workaround for the quirky quirks API is to add a new CAP. Actually advertise the set of quirks that can be disabled to userspace so it can predict KVM's behavior. Reject values for cap->args[0] that contain invalid bits. Finally, add documentation for the new capability and describe the existing quirks.

First set of new device support, fixes, cleanups and features for IIO in 5.18
This cycle we had quite a few series that applied similar changes
to lots of drivers. To keep this description manageable I have
called those out in their own section rather than per driver.
Particularly pleased to see the long running AFE precision series
going in this cycle.
Series includes some late breaking fixes.
New device support
* adi,ada4250 amplifier
- New driver and dt bindings for this programmable gain amplifier.
* adi,admv1014 microwave down-converter
- New driver, dt bindings and some device specific ABI that
may be generalized as more drivers for devices similar to this
are added.
* adi,admv4420 K Band down-converter.
- New driver and dt bindings.
* adi,adxl367 accelerometer driver.
- New driver, dt-bindings + some new IIO ABI definitions to support
reference magnitude events where an estimate of the acceleration
due to gravity has been removed.
- A few fixes as follow up patches.
* adi,ltc2688 DAC with toggle and dither modes.
- New driver and bindings. Includes some new driver specific (for now)
ABI for handling toggle mode and the addition of a dither waveform to
the DAC output.
* AFE (analog front end) add support for additional types of analog device
in front of an ADC.
- RTD temperature sensors with dt bindings.
- Temperature transducers wit dt bindings.
- Related cleanup and features listed in other sections below.
* maxim,ds3502 potentiometer.
- Add support to ds1803 driver which required significant rework.
* mediatek,mt2701-auxadc driver
- Add mediatek,mt8186-auxadc - id table and chip specific info only.
* semtech,sx9324, semtech,ax9360
- Substantial refactoring of sx9310 to extract core logic for reuse
into a separate module
- New driver using this supporting sx9324 proximity sensors.
- New driver using this supporting sx9360 proximity sensors.
* silan,sc7a20
- Compatible with the st,lis2dh (or nearly anyway) so add ID and
chip specific info to enable support. Also silan vendor ID added
for dt-bindings.
Staging graduation
* adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
electric cars and similar.
- Substantial rework of driver required to bring inline with current
IIO best practice. An unusual device in IIO so some interesting features
we may see more of in future.
Multiple driver/core cleanup
- Use sysfs_emit() in simple locations where there is no path to change
to various core created attributes.
- Trivial white space fixes around inconsistency between space after { and
before } in id tables.
- Introduce new handling for fractional types to avoid repeated similar
implementations. Use this in 3 drivers. Note this is also targeted
at future use in the AFE driver and was motivated by discussions
around the precision related work on that driver.
- of related header cleanups - drop of*.h and add mod_devicetable.h as
appropriate.
- Move a number of symbol exports into IIO_* namespaces. Two categories,
1) Library used by multiple drivers e.g. st_sensors
2) Core driver module exporting functions used by bus specific modules.
A few related cleanups in this set.
- Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
similar to simplify drivers and take advantage of these new macros
allowing the compiler to do the job or removing unused code without
the need for __maybe_unused markings. Conversion of other drivers to
these new macros ongoing.
Features
* adi,adf4350
- Switch from of specific to generic device properties enabling use with
other firmware types.
* adi,adx345
- Switch from of specific to generic device properties.
- Add ACPI ID ADS0345
- Related driver cleanup.
* adi,hmc425a
- Switch from of specific to generic device properties.
* afe analog rescaler driver
- Wider range of types supported for scale.
- Support offset.
- Kunit tests.
* atlas,ezo-sensor
- Convert from of to device properties.
* fsl,mma8452
- Support mount matrix.
* infineon,dps310:
- Add ACPI ID IFX3100.
* invensense,mpu6050
- Convert to generic device properties.
* maxim,ds1803
- Add out_raw_available before supporting more devices.
- Convert from of specific to device properties.
* samsung,ssp_sensors
- Convert from of specific to device properties.
* st,stm32-timer trigger
- Convert from of specific to device properties.
* ti,hdc101x
- Add ACPI ID TXNW1010.
* ti,tsc2046:
- Add read_raw support to enable use of iio_hwmon and similar.
Fixes / cleanup.
* mailmap
- Update for Cai Huoqing
* MAINTAINERS
- Fix Analog Devices related links.
- Add entry for ADRF6780
- Add entry for ADMV1013
- Add entry for AD7293
- Add entry for ADMV8818
- Update files listed for adis-lib
* iio core:
- Fix wrong comment about current_mode being something a driver should
ever access.
- Use struct_size() rather than open coding in industrialio-hw-consumer
* adi,axl355
- Use units.h definitions instead of local versions.
* adi,adis-lib
- Simplify *updated_bits() macro
- Whitespace cleanup.
* afe - Note many of these fixes only apply to particular configurations
so the problems have probably not been seen in the wild, but will be
visible with new usecases enabled this cycle.
- Fix application of consumer scale for IIO_VAL_INT.
- Apply a scale of 1 when no scale is provided.
- Make best effort to establish a valid offset value for fractional
cases.
- Use s64 for scale calculations where parameters may be signed.
- Tidy up include order.
- Improve accuracy for small fractional sales
- Reduce risk of integer overflow.
* ams,as3935
- Use devm_delayed_work_autocancel() to replace open coded equivalent.
* aspeed,adc
- Fix wrong use of divider flag.
* atmel,sama5d2-adc
- Relax atmel,trigger-edge-type to optional.
- Drop Ludovic Desroches from listed maintainers of the dt-binding
inline with previous MAINTAINERS entry update.
* fsl,mma8452
- Fix probing when i2c_device_id used.
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead. Note the original path in here
worked more by luck than design.
* invensense,mpu6050
- Drop ACPI_PTR() protection to avoid an unused warning.
- Use fact ACPI_COMPANION() returns null when ACPI_HANDLE() does to
simplify handling.
* motorola,cpcap-adc
- Drop unused assignment.
* qcom,spmi-adc
- Fix wrong example of 'reg' in binding document.
* renesas,rzg2l-adc
- Trivial typo fix.
* semtech,sx9360
- Fix wrong register handling for event generation.
* st_sensors

board. Default is still to enable the bus specific module if
appropriate bus is supported.
* st,lsm6dsx
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead.
* ti,palmas-gpadc
- Split the interrupt fields in the dt-binding example
* ti,tsc2046
- Rework state machine to improve readability after recent debugging of
an issue fixed elsewhere.
- Add a sanity check to avoid very large memory allocations if a crazy
delay is specified.
* ti,twl6030
- Add error handling if devm_request_threaded_irq() fails.
* xilinx,ams
- Use devm_delayed_work_autocancel() instead of open coding equivalent.
- Fix missing required clock entry in dt-binding.
- Fix miss counting of channels resulting in ps channels not
being enabled.
- Fix incorrect values written to sequencer registers.
- Fix sequence for single channel reading.

First set of new device support, fixes, cleanups and features for IIO in 5.18
This cycle we had quite a few series that applied similar changes
to lots of drivers. To keep this description manageable I have
called those out in their own section rather than per driver.
Particularly pleased to see the long running AFE precision series
going in this cycle.
Series includes some late breaking fixes.
New device support
* adi,ada4250 amplifier
- New driver and dt bindings for this programmable gain amplifier.
* adi,admv1014 microwave down-converter
- New driver, dt bindings and some device specific ABI that
may be generalized as more drivers for devices similar to this
are added.
* adi,admv4420 K Band down-converter.
- New driver and dt bindings.
* adi,adxl367 accelerometer driver.
- New driver, dt-bindings + some new IIO ABI definitions to support
reference magnitude events where an estimate of the acceleration
due to gravity has been removed.
- A few fixes as follow up patches.
* adi,ltc2688 DAC with toggle and dither modes.
- New driver and bindings. Includes some new driver specific (for now)
ABI for handling toggle mode and the addition of a dither waveform to
the DAC output.
* AFE (analog front end) add support for additional types of analog device
in front of an ADC.
- RTD temperature sensors with dt bindings.
- Temperature transducers wit dt bindings.
- Related cleanup and features listed in other sections below.
* maxim,ds3502 potentiometer.
- Add support to ds1803 driver which required significant rework.
* mediatek,mt2701-auxadc driver
- Add mediatek,mt8186-auxadc - id table and chip specific info only.
* semtech,sx9324, semtech,ax9360
- Substantial refactoring of sx9310 to extract core logic for reuse
into a separate module
- New driver using this supporting sx9324 proximity sensors.
- New driver using this supporting sx9360 proximity sensors.
* silan,sc7a20
- Compatible with the st,lis2dh (or nearly anyway) so add ID and
chip specific info to enable support. Also silan vendor ID added
for dt-bindings.
Staging graduation
* adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
electric cars and similar.
- Substantial rework of driver required to bring inline with current
IIO best practice. An unusual device in IIO so some interesting features
we may see more of in future.
Multiple driver/core cleanup
- Use sysfs_emit() in simple locations where there is no path to change
to various core created attributes.
- Trivial white space fixes around inconsistency between space after { and
before } in id tables.
- Introduce new handling for fractional types to avoid repeated similar
implementations. Use this in 3 drivers. Note this is also targeted
at future use in the AFE driver and was motivated by discussions
around the precision related work on that driver.
- of related header cleanups - drop of*.h and add mod_devicetable.h as
appropriate.
- Move a number of symbol exports into IIO_* namespaces. Two categories,
1) Library used by multiple drivers e.g. st_sensors
2) Core driver module exporting functions used by bus specific modules.
A few related cleanups in this set.
- Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
similar to simplify drivers and take advantage of these new macros
allowing the compiler to do the job or removing unused code without
the need for __maybe_unused markings. Conversion of other drivers to
these new macros ongoing.
Features
* adi,adf4350
- Switch from of specific to generic device properties enabling use with
other firmware types.
* adi,adx345
- Switch from of specific to generic device properties.
- Add ACPI ID ADS0345
- Related driver cleanup.
* adi,hmc425a
- Switch from of specific to generic device properties.
* afe analog rescaler driver
- Wider range of types supported for scale.
- Support offset.
- Kunit tests.
* atlas,ezo-sensor
- Convert from of to device properties.
* fsl,mma8452
- Support mount matrix.
* infineon,dps310:
- Add ACPI ID IFX3100.
* invensense,mpu6050
- Convert to generic device properties.
* maxim,ds1803
- Add out_raw_available before supporting more devices.

- Add entry for ADMV8818
- Update files listed for adis-lib
* iio core:
- Fix wrong comment about current_mode being something a driver should
ever access.
- Use struct_size() rather than open coding in industrialio-hw-consumer
* adi,axl355
- Use units.h definitions instead of local versions.
* adi,adis-lib
- Simplify *updated_bits() macro
- Whitespace cleanup.
* afe - Note many of these fixes only apply to particular configurations
so the problems have probably not been seen in the wild, but will be
visible with new usecases enabled this cycle.
- Fix application of consumer scale for IIO_VAL_INT.
- Apply a scale of 1 when no scale is provided.
- Make best effort to establish a valid offset value for fractional
cases.
- Use s64 for scale calculations where parameters may be signed.

* aspeed,adc
- Fix wrong use of divider flag.
* atmel,sama5d2-adc
- Relax atmel,trigger-edge-type to optional.
- Drop Ludovic Desroches from listed maintainers of the dt-binding
inline with previous MAINTAINERS entry update.
* fsl,mma8452
- Fix probing when i2c_device_id used.
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead. Note the original path in here
worked more by luck than design.
* invensense,mpu6050
- Drop ACPI_PTR() protection to avoid an unused warning.
- Use fact ACPI_COMPANION() returns null when ACPI_HANDLE() does to
simplify handling.
* motorola,cpcap-adc

board. Default is still to enable the bus specific module if
appropriate bus is supported.
* st,lsm6dsx
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead.
* ti,palmas-gpadc
- Split the interrupt fields in the dt-binding example
* ti,tsc2046
- Rework state machine to improve readability after recent debugging of
an issue fixed elsewhere.
- Add a sanity check to avoid very large memory allocations if a crazy
delay is specified.
* ti,twl6030
- Add error handling if devm_request_threaded_irq() fails.
* xilinx,ams
- Use devm_delayed_work_autocancel() instead of open coding equivalent.
- Fix missing required clock entry in dt-binding.
- Fix miss counting of channels resulting in ps channels not
being enabled.
- Fix incorrect values written to sequencer registers.
- Fix sequence for single channel reading.

Documentation: syfs-class-firmware-attributes: Lenovo Certificate support
Certificate based authentication is available as an alternative to password based authentication. The WMI commands are cryptographically signed using a separate signing server and will be verified by the BIOS before being accepted. This commit details the fields that are needed to support that implementation. At present the changes are intended for Lenovo platforms, but have been designed to keep them as flexible as possible for future implementations from other vendors.

netfs: Rename read_helper.c to io.c

netfs: Add a netfs inode context
Add a netfs_i_context struct that should be included in the network
filesystem's own inode struct wrapper, directly after the VFS's inode
struct, e.g.:
struct my_inode {
struct {
/* These must be contiguous */
struct inode vfs_inode;
struct netfs_i_context netfs_ctx;
};
};
The netfs_i_context struct so far contains a single field for the network
filesystem to use - the cache cookie:
struct netfs_i_context {
...
struct fscache_cookie *cache;
};
Three functions are provided to help with this:
(1) void netfs_i_context_init(struct inode *inode,
const struct netfs_request_ops *ops);
Initialise the netfs context and set the operations.
(2) struct netfs_i_context *netfs_i_context(struct inode *inode);
Find the netfs context from the VFS inode.
(3) struct inode *netfs_inode(struct netfs_i_context *ctx);
Find the VFS inode from the netfs context.
Changes
=======
ver #4)
- Fix netfs_is_cache_enabled() to check cookie->cache_priv to see if a
cache is present[3].
- Fix netfs_skip_folio_read() to zero out all of the page, not just some
of it[3].
ver #3)
- Split out the bit to move ceph cap-getting on readahead into
ceph_init_request()[1].
- Stick in a comment to the netfs inode structs indicating the contiguity
requirements[2].
ver #2)
- Adjust documentation to match.
- Use "#if IS_ENABLED()" in netfs_i_cookie(), not "#ifdef".
- Move the cap check from ceph_readahead() to ceph_init_request() to be
called from netfslib.
- Remove ceph_readahead() and use netfs_readahead() directly instead.
