iov_iter: Kunit tests for page extraction
Add some kunit tests for page extraction for ITER_BVEC, ITER_KVEC and ITER_XARRAY type iterators. ITER_UBUF and ITER_IOVEC aren't dealt with as they require userspace VM interaction. ITER_DISCARD isn't dealt with either as that can't be extracted.

iov_iter: Kunit tests for copying to/from an iterator
Add some kunit tests for page extraction for ITER_BVEC, ITER_KVEC and ITER_XARRAY type iterators. ITER_UBUF and ITER_IOVEC aren't dealt with as they require userspace VM interaction.

iov_iter: Fix iov_iter_extract_pages() with zero-sized entries
iov_iter_extract_pages() doesn't correctly handle skipping over initial
zero-length entries in ITER_KVEC and ITER_BVEC-type iterators.
The problem is that it accidentally reduces maxsize to 0 when it
skipping and thus runs to the end of the array and returns 0.
Fix this by sticking the calculated size-to-copy in a new variable
rather than back in maxsize.

raid6: Add LoongArch SIMD recovery implementation
Similar to the syndrome calculation, the recovery algorithms also work on 64 bytes at a time to align with the L1 cache line size of current and future LoongArch cores (that we care about). Which means unrolled-by-4 LSX and unrolled-by-2 LASX code. The assembly is originally based on the x86 SSSE3/AVX2 ports, but register allocation has been redone to take advantage of LSX/LASX's 32 vector registers, and instruction sequence has been optimized to suit (e.g. LoongArch can perform per-byte srl and andi on vectors, but x86 cannot). Performance numbers measured by instrumenting the raid6test code, on a 3A5000 system clocked at 2.5GHz: > lasx 2data: 354.987 MiB/s > lasx datap: 350.430 MiB/s > lsx 2data: 340.026 MiB/s > lsx datap: 337.318 MiB/s > intx1 2data: 164.280 MiB/s > intx1 datap: 187.966 MiB/s Because recovery algorithms are chosen solely based on priority and availability, lasx is marked as priority 2 and lsx priority 1. At least for the current generation of LoongArch micro-architectures, LASX should always be faster than LSX whenever supported, and have similar power consumption characteristics (because the only known LASX-capable uarch, the LA464, always compute the full 256-bit result for vector ops).

raid6: Add LoongArch SIMD syndrome calculation
The algorithms work on 64 bytes at a time, which is the L1 cache line size of all current and future LoongArch cores (that we care about), as confirmed by Huacai. The code is based on the generic int.uc algorithm, unrolled 4 times for LSX and 2 times for LASX. Further unrolling does not meaningfully improve the performance according to experiments.

xarray: Document necessary flag in alloc functions
Adds a new line to the docstrings of functions wrapping __xa_alloc() and __xa_alloc_cyclic(), informing about the necessity of flag XA_FLAGS_ALLOC being set previously. The documentation so far says that functions wrapping __xa_alloc() and __xa_alloc_cyclic() are supposed to return either -ENOMEM or -EBUSY in case of an error. If the xarray has been initialized without the flag XA_FLAGS_ALLOC, however, they fail with a different, undocumented error code. As hinted at in Documentation/core-api/xarray.rst, wrappers around these functions should only be invoked when the flag has been set. The functions' documentation should reflect that as well.

percpu: changes for v6.6
percpu * A couple cleanups by Baoquan He and Bibo Mao. The only behavior change is to start printing messages if we're under the warn limit for failed atomic allocations. percpu_counter * Shakeel introduced percpu counters into mm_struct which caused percpu allocations be on the hot path [1]. Originally I spent some time trying to improve the percpu allocator, but instead preferred what Mateusz Guzik proposed grouping at the allocation site, percpu_counter_init_many(). This allows a single percpu allocation to be shared by the counters. I like this approach because it creates a shared lifetime by the allocations. Additionally, I believe many inits have higher level synchronization requirements, like percpu_counter does against HOTPLUG_CPU. Therefore we can group these optimizations together.

lib/Kconfig.debug: Restrict DEBUG_INFO_SPLIT for RISC-V
When building for ARCH=riscv using LLVM < 14, there is an error with CONFIG_DEBUG_INFO_SPLIT=y: error: A dwo section may not contain relocations This was worked around in LLVM 15 by disallowing '-gsplit-dwarf' with '-mrelax' (the default), so CONFIG_DEBUG_INFO_SPLIT is not selectable with newer versions of LLVM: $ clang --target=riscv64-linux-gnu -gsplit-dwarf -c -o /dev/null -x c /dev/null clang: error: -gsplit-dwarf is unsupported with RISC-V linker relaxation (-mrelax) GCC silently had a similar issue that was resolved with GCC 12.x. Restrict CONFIG_DEBUG_INFO_SPLIT for RISC-V when using LLVM or GCC < 12.x to avoid these known issues.

riscv: enable DEBUG_FORCE_FUNCTION_ALIGN_64B
Allow to force all function address 64B aligned as it is possible for
other architectures. This may be useful when verify if performance
bump is caused by function alignment changes.

This pull request is full of clk driver changes. In fact, there aren't any
changes to the clk framework this time around. That's probably because everyone
was on vacation (yours truly included). We did lose a couple clk drivers this
time around because nobody was using those devices. That skews the diffstat a
bit, but either way, nothing looks out of the ordinary here. The usual suspects
are chugging along adding support for more SoCs and fixing bugs.
If I had to choose, I'd say the theme for the past few months has been
"polish". There's quite a few patches that migrate to
devm_platform_ioremap_resource() in here. And there's more than a handful of
patches that move the NR_CLKS define from the DT binding header to the driver.
There's even patches that migrate drivers to use clk_parent_data and clk_hw to
describe clk tree topology. It seems that the spring (summer?) cleaning bug got
some folks, or the semiconductor shortage finally hit the software side.
New Drivers:
- StarFive JH7110 SoC clock drivers
- Qualcomm IPQ5018 Global Clock Controller driver
- Versa3 clk generator to support 48KHz playback/record with audio codec on
RZ/G2L SMARC EVK
Removed Drivers:
- Remove non-OF mmp clk drivers
- Remove OXNAS clk driver
Updates:
- Add __counted_by to struct clk_hw_onecell_data and struct spmi_pmic_div_clk_cc
- Move defines for numbers of clks (NR_CLKS) from DT headers to drivers
- Introduce kstrdup_and_replace() and use it
- Add PLL rates for Rockchip rk3568
- Add the display clock tree for Rockchip rv1126
- Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and RZ/G2 SoCs
- Convert sun9i-mmc clock to use devm_platform_get_and_ioremap_resource()
- Fix function name in a comment in ccu_mmc_timing.c
- Parameter name correction for ccu_nkm_round_rate()
- Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e. consider alternative
parent rates when determining clock rates
- Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
- Support finding closest (as opposed to closest but not higher) clock rate
for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0
- Prefer current parent rate if able to generate ideal clock rate for Allwinner NKM clocks
- Clean up Qualcomm SMD RPM driver, with interconnect bus clocks moved out to
the interconnect drivers
- Fix various PM runtime bugs across many Qualcomm clk drivers
- Migrate Qualcomm MDM9615 is to parent_hw and parent_data
- Add network related resets on Qualcomm IPQ4019
- Add a couple missing USB related clocks to Qualcomm IPQ9574
- Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock controller
- In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs, and GPLL1 are
added, while PCIe pipe clock, SDCC rcg ops are corrected
- Add missing GDSCs to and correct GDSCs for the SC8280XP global clock controller driver
- Support retention for the Qualcomm SC8280XP display clock controller GDSCs.
- Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE to fix
issues with missing parent clocks across sc7180, sm7150, sm6350 and sm8250,
while sm8450 is corrected to use floor ops
- Correct Qualcomm SM6350 GPU clock controller's clock supplies
- Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver
- Add missing OXILICX GDSC to Qualcomm MSM8226 GCC
- Change the delay in the Qualcomm reset controller to fsleep() for correctness
- Extend the Qualcomm SM83550 Video clock controller to support SC8280XP
- Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and R-Car H3,
M3-W, and M3-N SoCs
- Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M
- Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five
- Add the PDM IPC clock for i.MX93
- Add 519.75MHz frequency support for i.MX9 PLL
- Simplify the .determine_rate() implementation for i.MX GPR mux
- Make the i.MX8QXP LPCG clock use devm_platform_ioremap_resource()
- Add the audio mux clock to i.MX8
- Fix the SPLL2 MULT range for PLLv4
- Update the SPLL2 type in i.MX8ULP
- Fix the SAI4 clock on i.MX8MP
- Add silicon revision print for i.MX25 on clocks init
- Drop the return value from __mx25_clocks_init()
- Fix the clock pauses on no-op set_rate for i.MX8M composite clock
- Drop restrictions for i.MX PLL14xx and fix its max prediv value
- Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to allow
glitch free switching

sound updates for 6.6-rc1
We've received a fairly wide range of changes at this time, including
for ALSA and ASoC core, but all of them are rather small changes.
Here are some highlights:
ALSA / ASoC Core:
- Fixes of inconsistent locking around control API helpers
- A few new control API functions and cleanups
- Workarounds for potential UAFs by delayed kobj releases
- Unified PCM copy ops with iov_iter
- Continued efforts for ASoC API cleanups
ASoC:
- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes
- Create a library function for intlog10() and use it in the NAU8825
driver
- Convert drivers to use the more modern maple tree register cache
- Lots of work on the SOF framework, AMD and Intel drivers, including a
lot of cleanup and new device support
- Standardization of the presentation of jacks from drivers
- Provision of some generic sound card DT properties
- Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
platforms including AVS machines with ES8336 and RT5663, Mediatek
MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
Others:
- New test coverage including ASoC and topology tests in KUnit;
this also involves enabling UML builds of ALSA since that's the
default KUnit test environment which pulls in the addition of some
stubs to the driver
- More enhancement of pcmtest driver
- A few fixes / enhancements of MIDI 2.0 UMP core
- Using PCI definitions in allover HD-audio code
- Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs
- CS35L41 HD-audio sub-codec improvements
- Continued emu10k1 improvements

Networking changes for 6.6.
Core
----
- Increase size limits for to-be-sent skb frag allocations. This
allows tun, tap devices and packet sockets to better cope with large
writes operations.
- Store netdevs in an xarray, to simplify iterating over netdevs.
- Refactor nexthop selection for multipath routes.
- Improve sched class lifetime handling.
- Add backup nexthop ID support for bridge.
- Implement drop reasons support in openvswitch.
- Several data races annotations and fixes.
- Constify the sk parameter of routing functions.
- Prepend kernel version to netconsole message.
Protocols
---------
- Implement support for TCP probing the peer being under memory
pressure.
- Remove hard coded limitation on IPv6 specific info placement
inside the socket struct.
- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
per socket scaling factor.
- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes.
- In-kernel support for the TLS alert protocol.
- Better support for UDP reuseport with connected sockets.
- Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
header size.
- Get rid of additional ancillary per MPTCP connection struct socket.
- Implement support for BPF-based MPTCP packet schedulers.
- Format MPTCP subtests selftests results in TAP.
- Several new SMC 2.1 features including unique experimental options,
max connections per lgr negotiation, max links per lgr negotiation.
BPF
---
- Multi-buffer support in AF_XDP.
- Add multi uprobe BPF links for attaching multiple uprobes
and usdt probes, which is significantly faster and saves extra fds.
- Implement an fd-based tc BPF attach API (TCX) and BPF link support on
top of it.
- Add SO_REUSEPORT support for TC bpf_sk_assign.
- Support new instructions from cpu v4 to simplify the generated code and
feature completeness, for x86, arm64, riscv64.
- Support defragmenting IPv(4|6) packets in BPF.
- Teach verifier actual bounds of bpf_get_smp_processor_id()
and fix perf+libbpf issue related to custom section handling.
- Introduce bpf map element count and enable it for all program types.
- Add a BPF hook in sys_socket() to change the protocol ID
from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
- Add uprobe support for the bpf_get_func_ip helper.
- Check skb ownership against full socket.
- Support for up to 12 arguments in BPF trampoline.
- Extend link_info for kprobe_multi and perf_event links.
Netfilter
---------
- Speed-up process exit by aborting ruleset validation if a
fatal signal is pending.
- Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
Driver API
----------
- Page pool optimizations, to improve data locality and cache usage.
- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
for raw ioctl() handling in drivers.
- Simplify genetlink dump operations (doit/dumpit) providing them
the common information already populated in struct genl_info.
- Extend and use the yaml devlink specs to [re]generate the split ops.
- Introduce devlink selective dumps, to allow SF filtering SF based on
handle and other attributes.
- Add yaml netlink spec for netlink-raw families, allow route, link and
address related queries via the ynl tool.
- Remove phylink legacy mode support.
- Support offload LED blinking to phy.
- Add devlink port function attributes for IPsec.

New code for 6.6:
* Make large writes to the page cache fill sparse parts of the cache
with large folios, then use large memcpy calls for the large folio.
* Track the per-block dirty state of each large folio so that a
buffered write to a single byte on a large folio does not result in a
(potentially) multi-megabyte writeback IO.
* Allow some directio completions to be performed in the initiating
task's context instead of punting through a workqueue. This will
reduce latency for some io_uring requests.

Pull iomap updates from Darrick Wong:
"We've got some big changes for this release -- I'm very happy to be
landing willy's work to enable large folios for the page cache for
general read and write IOs when the fs can make contiguous space
allocations, and Ritesh's work to track sub-folio dirty state to
eliminate the write amplification problems inherent in using large
folios.
As a bonus, io_uring can now process write completions in the caller's
context instead of bouncing through a workqueue, which should reduce
io latency dramatically. IOWs, XFS should see a nice performance bump
for both IO paths.
Summary:
- Make large writes to the page cache fill sparse parts of the cache

- Track the per-block dirty state of each large folio so that a
buffered write to a single byte on a large folio does not result in
a (potentially) multi-megabyte writeback IO.
- Allow some directio completions to be performed in the initiating

reduce latency for some io_uring requests"

lib/genalloc: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

lib/clz_ctz.c: Fix __clzdi2() and __ctzdi2() for 32-bit kernels
The gcc compiler translates on some architectures the 64-bit
__builtin_clzll() function to a call to the libgcc function __clzdi2(),
which should take a 64-bit parameter on 32- and 64-bit platforms.
But in the current kernel code, the built-in __clzdi2() function is
defined to operate (wrongly) on 32-bit parameters if BITS_PER_LONG ==
32, thus the return values on 32-bit kernels are in the range from
[0..31] instead of the expected [0..63] range.
This patch fixes the in-kernel functions __clzdi2() and __ctzdi2() to
take a 64-bit parameter on 32-bit kernels as well, thus it makes the
functions identical for 32- and 64-bit kernels.
This bug went unnoticed since kernel 3.11 for over 10 years, and here
are some possible reasons for that:
a) Some architectures have assembly instructions to count the bits and
which are used instead of calling __clzdi2(), e.g. on x86 the bsr
instruction and on ppc cntlz is used. On such architectures the
wrong __clzdi2() implementation isn't used and as such the bug has
no effect and won't be noticed.
b) Some architectures link to libgcc.a, and the in-kernel weak
functions get replaced by the correct 64-bit variants from libgcc.a.
c) __builtin_clzll() and __clzdi2() doesn't seem to be used in many
places in the kernel, and most likely only in uncritical functions,
e.g. when printing hex values via seq_put_hex_ll(). The wrong return
value will still print the correct number, but just in a wrong
formatting (e.g. with too many leading zeroes).
d) 32-bit kernels aren't used that much any longer, so they are less
tested.
A trivial testcase to verify if the currently running 32-bit kernel is
affected by the bug is to look at the output of /proc/self/maps:
Here the kernel uses a correct implementation of __clzdi2():
root@debian:~# cat /proc/self/maps
00010000-00019000 r-xp 00000000 08:05 787324 /usr/bin/cat
00019000-0001a000 rwxp 00009000 08:05 787324 /usr/bin/cat
0001a000-0003b000 rwxp 00000000 00:00 0 [heap]
f7551000-f770d000 r-xp 00000000 08:05 794765 /usr/lib/hppa-linux-gnu/libc.so.6
...
and this kernel uses the broken implementation of __clzdi2():
root@debian:~# cat /proc/self/maps
0000000010000-0000000019000 r-xp 00000000 000000008:000000005 787324 /usr/bin/cat

pcpcntr: add group allocation/free
Allocations and frees are globally serialized on the pcpu lock (and the CPU hotplug lock if enabled, which is the case on Debian). At least one frequent consumer allocates 4 back-to-back counters (and frees them in the same manner), exacerbating the problem. While this does not fully remedy scalability issues, it is a step towards that goal and provides immediate relief.

This is because all expected values were calculated for X86 which
is little endian. On big endian systems all precalculated 16 bits
halves must be byte swapped.
And this is confirmed by a huge amount of sparse errors when building
with C=2
So fix all sparse errors and it will naturally work on all endianness.

minmax: add in_range() macro
Patch series "New page table range API", v6.
This patchset changes the API used by the MM to set up page table entries.
The four APIs are:
set_ptes(mm, addr, ptep, pte, nr)
update_mmu_cache_range(vma, addr, ptep, nr)
flush_dcache_folio(folio)
flush_icache_pages(vma, page, nr)
flush_dcache_folio() isn't technically new, but no architecture
implemented it, so I've done that for them. The old APIs remain around
but are mostly implemented by calling the new interfaces.
The new APIs are based around setting up N page table entries at once.
The N entries belong to the same PMD, the same folio and the same VMA, so
ptep++ is a legitimate operation, and locking is taken care of for you.
Some architectures can do a better job of it than just a loop, but I have
hesitated to make too deep a change to architectures I don't understand
well.
One thing I have changed in every architecture is that PG_arch_1 is now a
per-folio bit instead of a per-page bit when used for dcache clean/dirty
tracking. This was something that would have to happen eventually, and it
makes sense to do it now rather than iterate over every page involved in a
cache flush and figure out if it needs to happen.
The point of all this is better performance, and Fengwei Yin has measured
improvement on x86. I suspect you'll see improvement on your architecture
too. Try the new will-it-scale test mentioned here:
https://lore.kernel.org/linux-mm/20230206140639.538867-5-fengwei.yin@intel.com/
You'll need to run it on an XFS filesystem and have
CONFIG_TRANSPARENT_HUGEPAGE set.
This patchset is the basis for much of the anonymous large folio work
being done by Ryan, so it's received quite a lot of testing over the last
few months.
This patch (of 38):
Determine if a value lies within a range more efficiently (subtraction +
comparison vs two comparisons and an AND). It also has useful (under some
circumstances) behaviour if the range exceeds the maximum value of the
type. Convert all the conflicting definitions of in_range() within the
kernel; some can use the generic definition while others need their own
definition.

maple_tree: disable mas_wr_append() when other readers are possible
The current implementation of append may cause duplicate data and/or
incorrect ranges to be returned to a reader during an update. Although
this has not been reported or seen, disable the append write operation
while the tree is in rcu mode out of an abundance of caution.
During the analysis of the mas_next_slot() the following was
artificially created by separating the writer and reader code:
Writer: reader:
mas_wr_append
set end pivot
updates end metata
Detects write to last slot
last slot write is to start of slot
store current contents in slot
overwrite old end pivot
mas_next_slot():
read end metadata
read old end pivot
return with incorrect range
store new value
Alternatively:
Writer: reader:
mas_wr_append
set end pivot
updates end metata
Detects write to last slot
last lost write to end of slot
store value
mas_next_slot():
read end metadata
read old end pivot
read new end pivot
return with incorrect range
set old end pivot
There may be other accesses that are not safe since we are now updating
both metadata and pointers, so disabling append if there could be rcu
readers is the safest action.

kstrtox: consistently use _tolower()
We already use _tolower() in other places, so convert the one which open codes it. Link: https://lkml.kernel.org/r/20230817145919.543251-1-andriy.shevchenko@linux.intel.com Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

lib/vsprintf: declare no_hash_pointers in sprintf.h
Sparse is not happy to see non-static variable without declaration: lib/vsprintf.c:61:6: warning: symbol 'no_hash_pointers' was not declared. Should it be static? Declare respective variable in the sprintf.h. With this, add a comment to discourage its use if no real need.

lib/vsprintf: split out sprintf() and friends
Patch series "lib/vsprintf: Rework header inclusions", v3. Some patches that reduce the mess with the header inclusions related to vsprintf.c module. Each patch has its own description, and has no dependencies to each other, except the collisions over modifications of the same places. Hence the series. This patch (of 2): kernel.h is being used as a dump for all kinds of stuff for a long time. sprintf() and friends are used in many drivers without need of the full kernel.h dependency train with it. Here is the attempt on cleaning it up by splitting out sprintf() and friends.

maple_tree: replace data before marking dead in split and spanning store
Reorder the operations for split and spanning stores so that new data is placed in the tree prior to marking the old data as dead. This will limit re-walks on dead data to just once instead of a retry loop. The order of operations is as follows: Create the new data, put the new data in place, mark the top node of the old data as dead. Then repair parent links in the reused nodes through all levels of the tree, following the new nodes downwards. Finally walk the top dead node looking for nodes that are no longer used, or subtrees that should be destroyed (marked dead throughout then freed), follow the partially used nodes downwards to discover other dead nodes and subtrees.

maple_tree: change mas_adopt_children() parent usage
All calls to mas_adopt_children() currently pass the parent as the node in the maple state. Allow for the parent pointer that is passed in to be used instead.

maple_tree: introduce mas_put_in_tree()
mas_replace() has a single user that takes a flag which is now always true. Replace this function with mas_put_in_tree() to better align with mas_replace_node().
