SCSI misc on 20210702
This series consists of the usual driver updates (ufs, ibmvfc, megaraid_sas, lpfc, elx, mpi3mr, qedi, iscsi, storvsc, mpt3sas) with elx and mpi3mr being new drivers. The major core change is a rework to drop the status byte handling macros and the old bit shifted definitions and the rest of the updates are minor fixes. Signed-off-by: James E.J.

f2fs: compress: add nocompress extensions support
When we create a directory with enable compression, all file write into
directory will try to compress.But sometimes we may know, new file
cannot meet compression ratio requirements.
We need a nocompress extension to skip those files to avoid unnecessary
compress page test.
After add nocompress_extension, the priority should be:
dir_flag < comp_extention,nocompress_extension < comp_file_flag,
no_comp_file_flag.
Priority in between FS_COMPR_FL, FS_NOCOMP_FS, extensions:
* compress_extension=so; nocompress_extension=zip; chattr +c dir;
touch dir/foo.so; touch dir/bar.zip; touch dir/baz.txt; then foo.so
and baz.txt should be compresse, bar.zip should be non-compressed.
chattr +c dir/bar.zip can enable compress on bar.zip.
* compress_extension=so; nocompress_extension=zip; chattr -c dir;
touch dir/foo.so; touch dir/bar.zip; touch dir/baz.txt; then foo.so
should be compresse, bar.zip and baz.txt should be non-compressed.
chattr+c dir/bar.zip; chattr+c dir/baz.txt; can enable compress on
bar.zip and baz.txt.

This is the bulk of pin control changes for the v5.14 kernel:
New drivers:
- Last merge window we created a driver for the Ralink RT2880.
We are now moving the Ralink SoC pin control drivers out of the MIPS
architecture code and into the pin control subsystem. This concerns
RT288X, MT7620, RT305X, RT3883 and MT7621.
- Qualcomm SM6125 SoC pin control driver.
- Qualcomm spmi-gpio support for PM7325.
- Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)
- Mediatek MT8365 SoC pin controller.
- New device HID for the AMD GPIO controller.
Improvements:
- Pin bias config support for a slew of Renesas pin controllers.
- Incremental improvements and non-urgent bug fixes to the Renesas
SoC drivers.
- Implement irq_set_wake on the AMD pin controller so we can wake
up from external pin events.
Misc:
- Devicetree bindings for the Apple M1 pin controller, we will probably
see a proper driver for this soon as well.

Merge tag 'pinctrl-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.14 kernel. Not so
much going on. No core changes, just drivers.
The most interesting would be that MIPS Ralink is migrating to pin
control and we have some bindings but not yet code for the Apple M1
pin controller.
New drivers:
- Last merge window we created a driver for the Ralink RT2880. We are
now moving the Ralink SoC pin control drivers out of the MIPS
architecture code and into the pin control subsystem. This concerns
RT288X, MT7620, RT305X, RT3883 and MT7621.
- Qualcomm SM6125 SoC pin control driver.
- Qualcomm spmi-gpio support for PM7325.
- Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)
- Mediatek MT8365 SoC pin controller.
- New device HID for the AMD GPIO controller.
Improvements:
- Pin bias config support for a slew of Renesas pin controllers.
- Incremental improvements and non-urgent bug fixes to the Renesas
SoC drivers.
- Implement irq_set_wake on the AMD pin controller so we can wake up
from external pin events.
Misc:
- Devicetree bindings for the Apple M1 pin controller, we will
probably see a proper driver for this soon as well"

This round has a diffstat dominated by Qualcomm clk drivers. Honestly though
that's just a bunch of data so the diffstat reflects that. Looking beyond that
there's just a bunch of updates all around in various clk drivers. Renesas and
NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall
the driver changes look to be mostly enabling more clks and non-critical fixes
that we could hold until the next merge window.
I'm especially excited about the series from Arnd that graduates clkdev to be
the only implementation of clk_get() and clk_put(). That's a good step in the
right direction to migreate eveerything over to the common clk framework. Now
we don't have to worry about clkdev specific details, they're just part of the
clk API now.
Core:
- clkdev is now the only option, i.e. clk_get()/clk_put() is implemented in
only one place in the kernel instead of in drivers/clk/clkdev.c and in
architectures that want their own implementation
New Drivers:
- Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant Clock
Jitter Cleaner With Dual Loop PLLs
- Qualcomm MDM9607 GCC
- Qualcomm SC8180X display clks
- Qualcomm SM6125 GCC
- Qualcomm SM8250 CAMCC (camera)
- Renesas RZ/G2L SoC
- Hisilicon hi3559A SoC
Updates:
- Stop using clock-output-names in ST clk drivers (yay!)
- Support secure mode of STM32MP1 SoCs
- Improve clock support for Actions S500 SoC
- duty cycle setting support on qcom clks
- Add TI am33xx spread spectrum clock support
- Use determine_rate() for the Amlogic pll ops instead of round_rate()
- Restrict Amlogic gp0/1 and audio plls range on g12a/sm1
- Improve Amlogic axg-audio controller error on deferral
- Add NNA clocks on Amlogic g12a
- Reduce memory footprint of Rockchip PLL rate tables
- A fix for the newly added Rockchip rk3568 clk driver
- Exported clock for the newly added Rockchip video decoder
- Remove audio ipg clock from i.MX8MP
- Remove deprecated legacy clock binding for i.MX SCU clock driver
- Use common clk-imx8qxp for both i.MX8QXP and i.MX8QM
- Add multiple clocks to clk-imx8qxp driver (enet, hdmi, lcdif, audio,
parallel interface)
- Add dedicated clock ops for i.MX paralel interface
- Different fixes for clocks controlled by ATF on i.MX SoCs
- Add A53/A72 frequency scaling support i.MX clk-scu driver
- Add special case for DCSS clock on suspend for i.MX clk-scu driver
- Add parent save/restore on suspend/resume to i.MX clk-scu driver
- Skip runtime PM enablement for CPU clocks in i.MX clk-scu driver
- Remove the sys1_pll/sys2_pll clock gates for i.MX8MQ and their
bindings
- Tegra clk driver no longer deasserts resets on clk_enable as it
gets in the way of certain power-up sequences
- Fix compile testing for Tegra clk driver
- One patch to fix a divider on the Allwinner v3s Audio PLL
- Add support for CPU core clock boost modes on Renesas R-Car Gen3
- Add ISPCS (Image Signal Processor) clocks on Renesas R-Car V3U
- Switch SH/R-Mobile and R-Car "DIV6" clocks to .determine_rate()
and improve support for multiple parents
- Switch Renesas RZ/N1 divider clocks to .determine_rate()
- Add ZA2 (Audio Clock Generator) clock on Renesas R-Car D3
- Convert ar7 to common clk framework
- Convert ralink to common clk framework

ptp: support ptp physical/virtual clocks conversion
Support ptp physical/virtual clocks conversion via sysfs. There will be a new attribute n_vclocks under ptp physical clock sysfs. - In default, the value is 0 meaning only ptp physical clock is in use. - Setting the value can create corresponding number of ptp virtual clocks to use. But current physical clock is guaranteed to stay free running. - Setting the value back to 0 can delete virtual clocks and back use physical clock again. Another new attribute max_vclocks control the maximum number of ptp vclocks. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

kernel.h: split out kstrtox() and simple_strtox() to a separate header
kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out kstrtox() and simple_strtox() helpers. At the same time convert users in header and lib folders to use new header. Though for time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

mm: device exclusive memory access
Some devices require exclusive write access to shared virtual memory (SVM) ranges to perform atomic operations on that memory. This requires CPU page tables to be updated to deny access whilst atomic operations are occurring. In order to do this introduce a new swap entry type (SWP_DEVICE_EXCLUSIVE). When a SVM range needs to be marked for exclusive access by a device all page table mappings for the particular range are replaced with device exclusive swap entries. This causes any CPU access to the page to result in a fault. Faults are resovled by replacing the faulting entry with the original mapping. This results in MMU notifiers being called which a driver uses to update access permissions such as revoking atomic access. After notifiers have been called the device will no longer have exclusive access to the region. Walking of the page tables to find the target pages is handled by get_user_pages() rather than a direct page table walk. A direct page table walk similar to what migrate_vma_collect()/unmap() does could also have been utilised. However this resulted in more code similar in functionality to what get_user_pages() provides as page faulting is required to make the PTEs present and to break COW.

mm: rename migrate_pgmap_owner
MMU notifier ranges have a migrate_pgmap_owner field which is used by drivers to store a pointer. This is subsequently used by the driver callback to filter MMU_NOTIFY_MIGRATE events. Other notifier event types can also benefit from this filtering, so rename the 'migrate_pgmap_owner' field to 'owner' and create a new notifier initialisation function to initialise this field.

mm/rmap: split try_to_munlock from try_to_unmap
The behaviour of try_to_unmap_one() is difficult to follow because it performs different operations based on a fairly large set of flags used in different combinations. TTU_MUNLOCK is one such flag. However it is exclusively used by try_to_munlock() which specifies no other flags. Therefore rather than overload try_to_unmap_one() with unrelated behaviour split this out into it's own function and remove the flag.

mm: hugetlb: introduce CONFIG_HUGETLB_PAGE_FREE_VMEMMAP_DEFAULT_ON
When using HUGETLB_PAGE_FREE_VMEMMAP, the freeing unused vmemmap pages associated with each HugeTLB page is default off. Now the vmemmap is PMD mapped. So there is no side effect when this feature is enabled with no HugeTLB pages in the system. Someone may want to enable this feature in the compiler time instead of using boot command line. So add a config to make it default on when someone do not want to enable it via command line.

Add a kernel parameter hugetlb_free_vmemmap to enable the feature of freeing unused vmemmap pages associated with each hugetlb page on boot.

mm: hugetlb: alloc the vmemmap pages associated with each HugeTLB page
When we free a HugeTLB page to the buddy allocator, we need to allocate
the vmemmap pages associated with it. However, we may not be able to
allocate the vmemmap pages when the system is under memory pressure. In
this case, we just refuse to free the HugeTLB page. This changes behavior
in some corner cases as listed below:
1) Failing to free a huge page triggered by the user (decrease nr_pages).
User needs to try again later.
2) Failing to free a surplus huge page when freed by the application.
Try again later when freeing a huge page next time.
3) Failing to dissolve a free huge page on ZONE_MOVABLE via
offline_pages().
This can happen when we have plenty of ZONE_MOVABLE memory, but
not enough kernel memory to allocate vmemmmap pages. We may even
be able to migrate huge page contents, but will not be able to
dissolve the source huge page. This will prevent an offline
operation and is unfortunate as memory offlining is expected to
succeed on movable zones. Users that depend on memory hotplug
to succeed for movable zones should carefully consider whether the
memory savings gained from this feature are worth the risk of
possibly not being able to offline memory in certain situations.
4) Failing to dissolve a huge page on CMA/ZONE_MOVABLE via
alloc_contig_range() - once we have that handling in place. Mainly
affects CMA and virtio-mem.
Similar to 3). virito-mem will handle migration errors gracefully.
CMA might be able to fallback on other free areas within the CMA
region.
Vmemmap pages are allocated from the page freeing context. In order for
those allocations to be not disruptive (e.g. trigger oom killer)
__GFP_NORETRY is used. hugetlb_lock is dropped for the allocation because
a non sleeping allocation would be too fragile and it could fail too
easily under memory pressure. GFP_ATOMIC or other modes to access memory
reserves is not used because we want to prevent consuming reserves under
heavy hugetlb freeing.

In addition to bug fixes and cleanups, there are two new features for
ext4 in 5.14:
- Allow applications to poll on changes to /sys/fs/ext4/*/errors_count
- Add the ioctl EXT4_IOC_CHECKPOINT which allows the journal to be
checkpointed, truncated and discarded or zero'ed.

Adds an optional "metadata_only" feature that only promotes bios flagged with REQ_META.

Pull for IPMI driver for 4.14
Mostly a restructure of the kcs_bmc driver to make it easier to
use with different types of devices, and just to clean things up and
improve things.
Also some bug fixes for the kcs_bmc driver.
One fix to the IPMI watchdog to stop the timer when the action is none.
Not a big deal, but it's the right thing to do.

Pull timer updates from Thomas Gleixner:
"Time and clocksource/clockevent related updates:
Core changes:
- Infrastructure to support per CPU "broadcast" devices for per CPU
clockevent devices which stop in deep idle states. This allows us
to utilize the more efficient architected timer on certain ARM SoCs
for normal operation instead of permanentely using the slow to
access SoC specific clockevent device.
- Print the name of the broadcast/wakeup device in /proc/timer_list
- Make the clocksource watchdog more robust against delays between
reading the current active clocksource and the watchdog
clocksource. Such delays can be caused by NMIs, SMIs and vCPU
preemption.
Handle this by reading the watchdog clocksource twice, i.e. before
and after reading the current active clocksource. In case that the
two watchdog reads shows an excessive time delta, the read sequence
is repeated up to 3 times.
- Improve the debug output and add a test module for the watchdog
mechanism.
- Reimplementation of the venerable time64_to_tm() function with a
faster and significantly smaller version. Straight from the source,
i.e. the author of the related research paper contributed this!
Driver changes:
- No new drivers, not even new device tree bindings!
- Fixes, improvements and cleanups and all over the place"

Updates for the interrupt subsystem:
Core changes:
- Cleanup and simplification of common code to invoke the low level
interrupt flow handlers when this invocation requires irqdomain
resolution. Add the necessary core infrastructure.
- Provide a proper interface for modular PMU drivers to set the
interrupt affinity.
- Add a request flag which allows to exclude interrupts from spurious
interrupt detection. Useful especially for IPI handlers which always
return IRQ_HANDLED which turns the spurious interrupt detection into a
pointless waste of CPU cycles.
Driver changes:
- Bulk convert interrupt chip drivers to the new irqdomain low level flow
handler invocation mechanism.
- Add device tree bindings for the Renesas R-Car M3-W+ SoC
- Enable modular build of the Qualcomm PDC driver
- The usual small fixes and improvements.

mm/page_alloc: introduce vm.percpu_pagelist_high_fraction
This introduces a new sysctl vm.percpu_pagelist_high_fraction. It is
similar to the old vm.percpu_pagelist_fraction. The old sysctl increased
both pcp->batch and pcp->high with the higher pcp->high potentially
reducing zone->lock contention. However, the higher pcp->batch value also
potentially increased allocation latency while the PCP was refilled. This
sysctl only adjusts pcp->high so that zone->lock contention is potentially
reduced but allocation latency during a PCP refill remains the same.

mm/page_alloc: delete vm.percpu_pagelist_fraction
Patch series "Calculate pcp->high based on zone sizes and active CPUs", v2. The per-cpu page allocator (PCP) is meant to reduce contention on the zone lock but the sizing of batch and high is archaic and neither takes the zone size into account or the number of CPUs local to a zone. With larger zones and more CPUs per node, the contention is getting worse. Furthermore, the fact that vm.percpu_pagelist_fraction adjusts both batch and high values means that the sysctl can reduce zone lock contention but also increase allocation latencies. This series disassociates pcp->high from pcp->batch and then scales pcp->high based on the size of the local zone with limited impact to reclaim and accounting for active CPUs but leaves pcp->batch static. It also adapts the number of pages that can be on the pcp list based on recent freeing patterns. The motivation is partially to adjust to larger memory sizes but is also driven by the fact that large batches of page freeing via release_pages() often shows zone contention as a major part of the problem. Another is a bug report based on an older kernel where a multi-terabyte process can takes several minutes to exit. A workaround was to use vm.percpu_pagelist_fraction to increase the pcp->high value but testing indicated that a production workload could not use the same values because of an increase in allocation latencies. Unfortunately, I cannot reproduce this test case myself as the multi-terabyte machines are in active use but it should alleviate the problem. The series aims to address both and partially acts as a pre-requisite. pcp only works with order-0 which is useless for SLUB (when using high orders) and THP (unconditionally). To store high-order pages on PCP, the pcp->high values need to be increased first. This patch (of 6): The vm.percpu_pagelist_fraction is used to increase the batch and high limits for the per-cpu page allocator (PCP). The intent behind the sysctl is to reduce zone lock acquisition when allocating/freeing pages but it has a problem. While it can decrease contention, it can also increase latency on the allocation side due to unreasonably large batch sizes. This leads to games where an administrator adjusts percpu_pagelist_fraction on the fly to work around contention and allocation latency problems. This series aims to alleviate the problems with zone lock contention while avoiding the allocation-side latency problems. For the purposes of review, it's easier to remove this sysctl now and reintroduce a similar sysctl later in the series that deals only with pcp->high.

kasan: test: improve failure message in KUNIT_EXPECT_KASAN_FAIL()
The KUNIT_EXPECT_KASAN_FAIL() macro currently uses KUNIT_EXPECT_EQ() to
compare fail_data.report_expected and fail_data.report_found. This always
gave a somewhat useless error message on failure, but the addition of
extra compile-time checking with READ_ONCE() has caused it to get much
longer, and be truncated before anything useful is displayed.
Instead, just check fail_data.report_found by hand (we've just set
report_expected to 'true'), and print a better failure message with
KUNIT_FAIL(). Because of this, report_expected is no longer used
anywhere, and can be removed.
Beforehand, a failure in:
KUNIT_EXPECT_KASAN_FAIL(test, ((volatile char *)area)[3100]);
would have looked like:
[22:00:34] [FAILED] vmalloc_oob
[22:00:34] # vmalloc_oob: EXPECTATION FAILED at lib/test_kasan.c:991
[22:00:34] Expected ({ do { extern void __compiletime_assert_705(void) __attribute__((__error__("Unsupported access size for {READ,WRITE}_ONCE()."))); if (!((sizeof(fail_data.report_expected) == sizeof(char) || sizeof(fail_data.repp
[22:00:34] not ok 45 - vmalloc_oob
With this change, it instead looks like:
[22:04:04] [FAILED] vmalloc_oob
[22:04:04] # vmalloc_oob: EXPECTATION FAILED at lib/test_kasan.c:993
[22:04:04] KASAN failure expected in "((volatile char *)area)[3100]", but none occurred
[22:04:04] not ok 45 - vmalloc_oob
Also update the example failure in the documentation to reflect this.

mm/page_reporting: export reporting order as module parameter
The macro PAGE_REPORTING_MIN_ORDER is defined as the page reporting threshold. It can't be adjusted at runtime. This introduces a variable (@page_reporting_order) to replace the marcro (PAGE_REPORTING_MIN_ORDER). MAX_ORDER is assigned to it initially, meaning the page reporting is disabled. It will be specified by driver if valid one is provided. Otherwise, it will fall back to @pageblock_order. It's also exported so that the page reporting order can be adjusted at runtime.

net: dsa: delete dsa_legacy_fdb_add and dsa_legacy_fdb_del
We want to add reference counting for FDB entries in cross-chip topologies, and in order for that to have any chance of working and not be unbalanced (leading to entries which are never deleted), we need to ensure that higher layers are sane, because if they aren't, it's garbage in, garbage out. For example, if we add a bridge FDB entry twice, the bridge properly errors out: $ bridge fdb add dev swp0 00:01:02:03:04:07 master static $ bridge fdb add dev swp0 00:01:02:03:04:07 master static RTNETLINK answers: File exists However, the same thing cannot be said about the bridge bypass operations: $ bridge fdb add dev swp0 00:01:02:03:04:07 $ bridge fdb add dev swp0 00:01:02:03:04:07 $ bridge fdb add dev swp0 00:01:02:03:04:07 $ bridge fdb add dev swp0 00:01:02:03:04:07 $ echo $? 0 But one 'bridge fdb del' is enough to remove the entry, no matter how many times it was added. The bridge bypass operations are impossible to maintain in these circumstances and lack of support for reference counting the cross-chip notifiers is holding us back from making further progress, so just drop support for them. The only way left for users to install static bridge FDB entries is the proper one, using the "master static" flags. With this change, rtnl_fdb_add() falls back to calling ndo_dflt_fdb_add() which uses the duplicate-exclusive variant of dev_uc_add(): dev_uc_add_excl(). Because DSA does not (yet) declare IFF_UNICAST_FLT, this results in us going to promiscuous mode: $ bridge fdb add dev swp0 00:01:02:03:04:05 [ 28.206743] device swp0 entered promiscuous mode $ bridge fdb add dev swp0 00:01:02:03:04:05 RTNETLINK answers: File exists So even if it does not completely fail, there is at least some indication that it is behaving differently from before, and closer to user space expectations, I would argue (the lack of a "local|static" specifier defaults to "local", or "host-only", so dev_uc_add() is a reasonable default implementation). If the generic implementation of .ndo_fdb_add provided by Vlad Yasevich is a proof of anything, it only proves that the implementation provided by DSA was always wrong, by not looking at "ndm->ndm_state & NUD_NOARP" (the "static" flag which means that the FDB entry points outwards) and "ndm->ndm_state & NUD_PERMANENT" (the "local" flag which means that the FDB entry points towards the host). It all used to mean the same thing to DSA. Update the documentation so that the users are not confused about what's going on.

dt-bindings: mmc: change compatiable string for MT8195 mmc host IP
MT8195 mmc host IP is compatible with MT8183, and currently it shows:
properties:
compatible:
oneOf:
...
- items:
- const: mediatek,mt8192-mmc
- const: mediatek,mt8195-mmc
- const: mediatek,mt8183-mmc
which means the compatible string in the device tree would be:
compatible = "mediatek,mt8192-mmc", "mediatek,mt8195-mmc",
"mediatek,mt8183-mmc";
The bindings is wrong and that isn't the result we want.
instead we want:
properties:
compatible:
oneOf:
...
- items:
- const: mediatek,mt8192-mmc
- const: mediatek,mt8183-mmc
- items:
- const: mediatek,mt8195-mmc
- const: mediatek,mt8183-mmc
which would give us:
compatible = "mediatek,mt8192-mmc", "mediatek,mt8183-mmc";
and
compatible = "mediatek,mt8195-mmc", "mediatek,mt8183-mmc";

"There's a reasonable amount here and the juicy details are all below.
It's worth noting that the MTE/KASAN changes strayed outside of our

rather that take them via the -mm tree.

- Optimise SVE switching for CPUs with 128-bit implementations.
- Fix output format from SVE selftest.
- Add support for versions v1.2 and 1.3 of the SMC calling
convention.
- Allow Pointer Authentication to be configured independently for

Changes in this cycle were:
- Add the "ratelimit:N" parameter to the split_lock_detect= boot option,
to rate-limit the generation of bus-lock exceptions. This is both
easier on system resources and kinder to offending applications than
the current policy of outright killing them.
- Document the split-lock detection feature and its parameters.

Pull x86 splitlock updates from Ingo Molnar:
- Add the "ratelimit:N" parameter to the split_lock_detect= boot
option, to rate-limit the generation of bus-lock exceptions.
This is both easier on system resources and kinder to offending
applications than the current policy of outright killing them.
- Document the split-lock detection feature and its parameters.

seccomp: Support atomic "addfd + send reply"
Alban Crequy reported a race condition userspace faces when we want to add some fds and make the syscall return them[1] using seccomp notify. The problem is that currently two different ioctl() calls are needed by the process handling the syscalls (agent) for another userspace process (target): SECCOMP_IOCTL_NOTIF_ADDFD to allocate the fd and SECCOMP_IOCTL_NOTIF_SEND to return that value. Therefore, it is possible for the agent to do the first ioctl to add a file descriptor but the target is interrupted (EINTR) before the agent does the second ioctl() call. This patch adds a flag to the ADDFD ioctl() so it adds the fd and returns that value atomically to the target program, as suggested by Kees Cook[2]. This is done by simply allowing seccomp_do_user_notification() to add the fd and return it in this case. Therefore, in this case the target wakes up from the wait in seccomp_do_user_notification() either to interrupt the syscall or to add the fd and return it. This "allocate an fd and return" functionality is useful for syscalls that return a file descriptor only, like connect(2). Other syscalls that return a file descriptor but not as return value (or return more than one fd), like socketpair(), pipe(), recvmsg with SCM_RIGHTs, will not work with this flag. This effectively combines SECCOMP_IOCTL_NOTIF_ADDFD and SECCOMP_IOCTL_NOTIF_SEND into an atomic opteration. The notification's return value, nor error can be set by the user. Upon successful invocation of the SECCOMP_IOCTL_NOTIF_ADDFD ioctl with the SECCOMP_ADDFD_FLAG_SEND flag, the notifying process's errno will be 0, and the return value will be the file descriptor number that was installed.

Scheduler udpates for this cycle:
- Changes to core scheduling facilities:
- Add "Core Scheduling" via CONFIG_SCHED_CORE=y, which enables
coordinated scheduling across SMT siblings. This is a much
requested feature for cloud computing platforms, to allow
the flexible utilization of SMT siblings, without exposing
untrusted domains to information leaks & side channels, plus
to ensure more deterministic computing performance on SMT
systems used by heterogenous workloads.
There's new prctls to set core scheduling groups, which
allows more flexible management of workloads that can share
siblings.
- Fix task->state access anti-patterns that may result in missed
wakeups and rename it to ->__state in the process to catch new
abuses.
- Load-balancing changes:
- Tweak newidle_balance for fair-sched, to improve
'memcache'-like workloads.
- "Age" (decay) average idle time, to better track & improve workloads
such as 'tbench'.
- Fix & improve energy-aware (EAS) balancing logic & metrics.
- Fix & improve the uclamp metrics.
- Fix task migration (taskset) corner case on !CONFIG_CPUSET.
- Fix RT and deadline utilization tracking across policy changes
- Introduce a "burstable" CFS controller via cgroups, which allows
bursty CPU-bound workloads to borrow a bit against their future
quota to improve overall latencies & batching. Can be tweaked
via /sys/fs/cgroup/cpu/<X>/cpu.cfs_burst_us.
- Rework assymetric topology/capacity detection & handling.
- Scheduler statistics & tooling:
- Disable delayacct by default, but add a sysctl to enable
it at runtime if tooling needs it. Use static keys and
other optimizations to make it more palatable.
- Use sched_clock() in delayacct, instead of ktime_get_ns().
- Misc cleanups and fixes.

spi: Updates for v5.14
The biggest single thing in the diffstat here is a massive overhaul of
the PXA2xx driver from Andy Shevchenko (the IP is still in use on modern
Intel systems), though we also have quite a lot of core work as well:
- Better support for mixing native and GPIO chip selects also from
Andy.
- Support for devices with multiple chip selects from Sebastian
Reichel.
- Helper for polling status registers in spi-mem from Patrice Chotard.
- Support for Renesas RZ/N1 and Rockchip RV1126.

regulator: Updates for v5.14
The main core change this release is generic support for handling of
hardware errors from Matti Vaittinen, including some small updates to
the reboot and thermal code so we can share support for powering off the
system if things are going wrong enough. Otherwise this release we've
mainly seen the addition of new drivers, including MT6359 which has
pulled in some small changes from the MFD tree for build dependencies.
- Support for controlling the trigger points for hardware error
detection, and shared handlers for this.
- Support for Maxim MAX8993, Mediatek MT6359 and MT6359P, Qualcomm
PM8226 and SA8115P-ADP, and Sylergy TCS4526.

Pull libata updates from Jens Axboe:
"The big change in this round is that we're finally in a position where
we can sanely remove the old drivers/ide/ code, as libata covers
everything we need by now.
This is exciting for two reasons:
1) we delete a lot of legacy code that doesn't really meet the
standards we have today, and
2) it enables us to clean up various bits in the block layer that
exist only because of the old IDE code.
Outside of that, just a few minor fixes here, fixups for warnings,
etc"

trace: Add timerlat tracer
The timerlat tracer aims to help the preemptive kernel developers to
found souces of wakeup latencies of real-time threads. Like cyclictest,
the tracer sets a periodic timer that wakes up a thread. The thread then
computes a *wakeup latency* value as the difference between the *current
time* and the *absolute time* that the timer was set to expire. The main
goal of timerlat is tracing in such a way to help kernel developers.
Usage
Write the ASCII text "timerlat" into the current_tracer file of the
tracing system (generally mounted at /sys/kernel/tracing).
For example:
[root@f32 ~]# cd /sys/kernel/tracing/
[root@f32 tracing]# echo timerlat > current_tracer
It is possible to follow the trace by reading the trace trace file:
[root@f32 tracing]# cat trace
# tracer: timerlat

# / _----=> need-resched
# | / _---=> hardirq/softirq
# || / _--=> preempt-depth

<idle>-0 [001] dNh1 54.029346: #1 context irq timer_latency 2833 ns
<...>-868 [001] .... 54.029353: #1 context thread timer_latency 9820 ns
<idle>-0 [000] d.h1 54.030328: #2 context irq timer_latency 769 ns
<...>-867 [000] .... 54.030330: #2 context thread timer_latency 3070 ns
<idle>-0 [001] d.h1 54.030344: #2 context irq timer_latency 935 ns
<...>-868 [001] .... 54.030347: #2 context thread timer_latency 4351 ns
The tracer creates a per-cpu kernel thread with real-time priority that
prints two lines at every activation. The first is the *timer latency*
observed at the *hardirq* context before the activation of the thread.
The second is the *timer latency* observed by the thread, which is the
same level that cyclictest reports. The ACTIVATION ID field
serves to relate the *irq* execution to its respective *thread* execution.
The irq/thread splitting is important to clarify at which context
the unexpected high value is coming from. The *irq* context can be
delayed by hardware related actions, such as SMIs, NMIs, IRQs
or by a thread masking interrupts. Once the timer happens, the delay
can also be influenced by blocking caused by threads. For example, by
postponing the scheduler execution via preempt_disable(), by the
scheduler execution, or by masking interrupts. Threads can
also be delayed by the interference from other threads and IRQs.
The timerlat can also take advantage of the osnoise: traceevents.
For example:
[root@f32 ~]# cd /sys/kernel/tracing/
[root@f32 tracing]# echo timerlat > current_tracer
[root@f32 tracing]# echo osnoise > set_event
[root@f32 tracing]# echo 25 > osnoise/stop_tracing_total_us

trace: Add osnoise tracer
In the context of high-performance computing (HPC), the Operating System
Noise (*osnoise*) refers to the interference experienced by an application
due to activities inside the operating system. In the context of Linux,
NMIs, IRQs, SoftIRQs, and any other system thread can cause noise to the
system. Moreover, hardware-related jobs can also cause noise, for example,
via SMIs.
The osnoise tracer leverages the hwlat_detector by running a similar
loop with preemption, SoftIRQs and IRQs enabled, thus allowing all
the sources of *osnoise* during its execution. Using the same approach
of hwlat, osnoise takes note of the entry and exit point of any
source of interferences, increasing a per-cpu interference counter. The
osnoise tracer also saves an interference counter for each source of
interference. The interference counter for NMI, IRQs, SoftIRQs, and
threads is increased anytime the tool observes these interferences' entry
events. When a noise happens without any interference from the operating
system level, the hardware noise counter increases, pointing to a
hardware-related noise. In this way, osnoise can account for any
source of interference. At the end of the period, the osnoise tracer
prints the sum of all noise, the max single noise, the percentage of CPU
available for the thread, and the counters for the noise sources.
Usage
Write the ASCII text "osnoise" into the current_tracer file of the
tracing system (generally mounted at /sys/kernel/tracing).
For example::
[root@f32 ~]# cd /sys/kernel/tracing/
[root@f32 tracing]# echo osnoise > current_tracer
It is possible to follow the trace by reading the trace trace file::
[root@f32 tracing]# cat trace

<...>-865 [006] .... 81.638302: 1000000 109 99.98910 21 3 0 1006 18 1
<...>-866 [007] .... 81.638326: 1000000 7816 99.21840 107 8 0 1016 39 19
In addition to the regular trace fields (from TASK-PID to TIMESTAMP), the
tracer prints a message at the end of each period for each CPU that is
running an osnoise/CPU thread. The osnoise specific fields report:
- The RUNTIME IN USE reports the amount of time in microseconds that
the osnoise thread kept looping reading the time.
- The NOISE IN US reports the sum of noise in microseconds observed
by the osnoise tracer during the associated runtime.
- The % OF CPU AVAILABLE reports the percentage of CPU available for
the osnoise thread during the runtime window.
- The MAX SINGLE NOISE IN US reports the maximum single noise observed
during the runtime window.
- The Interference counters display how many each of the respective
interference happened during the runtime window.
Note that the example above shows a high number of HW noise samples.
The reason being is that this sample was taken on a virtual machine,
and the host interference is detected as a hardware interference.
Tracer options
The tracer has a set of options inside the osnoise directory, they are:
- osnoise/cpus: CPUs at which a osnoise thread will execute.
- osnoise/period_us: the period of the osnoise thread.
- osnoise/runtime_us: how long an osnoise thread will look for noise.
- osnoise/stop_tracing_us: stop the system tracing if a single noise
higher than the configured value happens. Writing 0 disables this
option.
- osnoise/stop_tracing_total_us: stop the system tracing if total noise
higher than the configured value happens. Writing 0 disables this
option.
- tracing_threshold: the minimum delta between two time() reads to be
considered as noise, in us. When set to 0, the default value will
be used, which is currently 5 us.
Additional Tracing
In addition to the tracer, a set of tracepoints were added to
facilitate the identification of the osnoise source.
- osnoise:sample_threshold: printed anytime a noise is higher than
the configurable tolerance_ns.
- osnoise:nmi_noise: noise from NMI, including the duration.
- osnoise:irq_noise: noise from an IRQ, including the duration.
- osnoise:softirq_noise: noise from a SoftIRQ, including the
duration.
- osnoise:thread_noise: noise from a thread, including the duration.
Note that all the values are *net values*. For example, if while osnoise
is running, another thread preempts the osnoise thread, it will start a
thread_noise duration at the start. Then, an IRQ takes place, preempting
the thread_noise, starting a irq_noise. When the IRQ ends its execution,
it will compute its duration, and this duration will be subtracted from
the thread_noise, in such a way as to avoid the double accounting of the
IRQ execution. This logic is valid for all sources of noise.
Here is one example of the usage of these tracepoints::
osnoise/8-961 [008] d.h. 5789.857532: irq_noise: local_timer:236 start 5789.857529929 duration 1845 ns
osnoise/8-961 [008] dNh. 5789.858408: irq_noise: local_timer:236 start 5789.858404871 duration 2848 ns
migration/8-54 [008] d... 5789.858413: thread_noise: migration/8:54 start 5789.858409300 duration 3068 ns
osnoise/8-961 [008] .... 5789.858413: sample_threshold: start 5789.858404555 duration 8723 ns interferences 2
In this example, a noise sample of 8 microseconds was reported in the last
line, pointing to two interferences. Looking backward in the trace, the
two previous entries were about the migration thread running after a
timer IRQ execution. The first event is not part of the noise because
it took place one millisecond before.
It is worth noticing that the sum of the duration reported in the
tracepoints is smaller than eight us reported in the sample_threshold.
The reason roots in the overhead of the entry and exit code that happens
before and after any interference execution. This justifies the dual
approach: measuring thread and tracing.

powerpc/papr_scm: Make 'perf_stats' invisible if perf-stats unavailable
In case performance stats for an nvdimm are not available, reading the
'perf_stats' sysfs file returns an -ENOENT error. A better approach is
to make the 'perf_stats' file entirely invisible to indicate that
performance stats for an nvdimm are unavailable.
So this patch updates 'papr_nd_attribute_group' to add a 'is_visible'
callback implemented as newly introduced 'papr_nd_attribute_visible()'
that returns an appropriate mode in case performance stats aren't
supported in a given nvdimm.
Also the initialization of 'papr_scm_priv.stat_buffer_len' is moved
from papr_scm_nvdimm_init() to papr_scm_probe() so that it value is
available when 'papr_nd_attribute_visible()' is called during nvdimm
initialization.
Even though 'perf_stats' attribute is available since v5.9, there are
no known user-space tools/scripts that are dependent on presence of its
sysfs file. Hence I dont expect any user-space breakage with this
patch.
Fixes:

kvm: x86: Allow userspace to handle emulation errors
Add a fallback mechanism to the in-kernel instruction emulator that allows userspace the opportunity to process an instruction the emulator was unable to. When the in-kernel instruction emulator fails to process an instruction it will either inject a #UD into the guest or exit to userspace with exit reason KVM_INTERNAL_ERROR. This is because it does not know how to proceed in an appropriate manner. This feature lets userspace get involved to see if it can figure out a better path forward.

KVM: x86/mmu: Rename "nxe" role bit to "efer_nx" for macro shenanigans
Rename "nxe" to "efer_nx" so that future macro magic can use the pattern <reg>_<bit> for all CR0, CR4, and EFER bits that included in the role. Using "efer_nx" also makes it clear that the role bit reflects EFER.NX, not the NX bit in the corresponding PTE.

KVM: x86: Alert userspace that KVM_SET_CPUID{,2} after KVM_RUN is broken
Warn userspace that KVM_SET_CPUID{,2} after KVM_RUN "may" cause guest
instability. Initialize last_vmentry_cpu to -1 and use it to detect if
the vCPU has been run at least once when its CPUID model is changed.
KVM does not correctly handle changes to paging related settings in the
guest's vCPU model after KVM_RUN, e.g. MAXPHYADDR, GBPAGES, etc... KVM
could theoretically zap all shadow pages, but actually making that happen
is a mess due to lock inversion (vcpu->mutex is held). And even then,
updating paging settings on the fly would only work if all vCPUs are
stopped, updated in concert with identical settings, then restarted.
To support running vCPUs with different vCPU models (that affect paging),
KVM would need to track all relevant information in kvm_mmu_page_role.
Note, that's the _page_ role, not the full mmu_role. Updating mmu_role
isn't sufficient as a vCPU can reuse a shadow page translation that was
created by a vCPU with different settings and thus completely skip the
reserved bit checks (that are tied to CPUID).
Tracking CPUID state in kvm_mmu_page_role is _extremely_ undesirable as
it would require doubling gfn_track from a u16 to a u32, i.e. would
increase KVM's memory footprint by 2 bytes for every 4kb of guest memory.
E.g. MAXPHYADDR (6 bits), GBPAGES, AMD vs. INTEL = 1 bit, and SEV C-BIT
would all need to be tracked.
In practice, there is no remotely sane use case for changing any paging
related CPUID entries on the fly, so just sweep it under the rug (after
yelling at userspace).

KVM: stats: Add documentation for binary statistics interface
This new API provides a file descriptor for every VM and VCPU to read KVM statistics data in binary format. It is meant to provide a lightweight, flexible, scalable and efficient lock-free solution for user space telemetry applications to pull the statistics data periodically for large scale systems. The pulling frequency could be as high as a few times per second. The statistics descriptors are defined by KVM in kernel and can be by userspace to discover VM/VCPU statistics during the one-time setup stage. The statistics data itself could be read out by userspace telemetry periodically without any extra parsing or setup effort. There are a few existed interface protocols and definitions, but no one can fulfil all the requirements this interface implemented as below: 1. During high frequency periodic stats reading, there should be no extra efforts except the stats data read itself. 2. Support stats annotation, like type (cumulative, instantaneous, peak, histogram, etc) and unit (counter, time, size, cycles, etc). 3. The stats data reading should be free of lock/synchronization. We don't care about the consistency between all the stats data. All stats data can not be read out at exactly the same time. We really care about the change or trend of the stats data. The lock-free solution is not just for efficiency and scalability, also for the stats data accuracy and usability. For example, in the situation that all the stats data readings are protected by a global lock, if one VCPU died somehow with that lock held, then all stats data reading would be blocked, then we have no way from stats data that which VCPU has died. 4. The stats data reading workload can be handed over to other unprivileged process.
