This adds support for controlling the PRU and R5F clusters on the TI
AM64x, the remote processor in i.MX7ULP, i.MX8MN/P and i.MX8ULP NXP and
the audio, compute and modem remoteprocs in the Qualcomm SC8180x
platform.
It fixes improper ordering of cdev and device creation of the remoteproc
control interface and it fixes resource leaks in the error handling path
of rproc_add() and the Qualcomm modem and wifi remoteproc drivers.
Lastly it fixes a few build warnings and replace the dummy parameter
passed in the mailbox api of the stm32 driver to something not living on
the stack.

A power domain should not be modelled as a regulator, not even for the
simplest case as recent discussions have concluded around the existing
regulator-fixed-domain DT binding.
Fortunately, there is only one user of the binding that was recently added.
Therefore, let's mark the binding as deprecated to prevent it from being
further used.

Pull gpio updates from Bartosz Golaszewski:
"One new driver, support for new models in existing ones, dt-bindings
conversions for several modules and improvements all over the place.
Summary:
- new driver for the IDT 79RC3243x GPIO controller
- device tree bindings coversion to YAML for the following drivers:
gpio-rk3328-grf, gpio-omap, gpio-davinci, gpio-zynq, gpio-stp,
gpio-pcf857x
- cleanup of probe functions in many drivers from Alexandru Ardelean,
mostly dropping unnecessary calls to platform_set_drvdata() and
removing error messages where none are needed (handled by the
subsystem already)
- several improvements to the core gpiolib and the sysfs interface
code from Andy Shevchenko
- conversion of the gpio-xilinx driver to using the bitmap API +
improvements of suspend/resume handling + minor tweaks
- convert the gpio-stmpe to using devres helpers exclusively in probe
for improved robustness
- updates for the generic gpio-regmap driver
- updates for the gpio-dwapb driver
- support for a new model in gpio-pca953x
- cleanups in gpio-tegra186, gpio-104-idio-16, gpio-mxs & gpio-xgene
- slight code refactoring of the gpio-zynq driver
- documentation fixes from Mauro Carvalho Chehab
- a bunch of minor tweaks and improvements all over the place"

Pull CXL (Compute Express Link) updates from Dan Williams:
"This subsystem is still in the build-out phase as the bulk of the
update is improvements to enumeration and fleshing out the device
model. In terms of new features, more mailbox commands have been added
to the allowed-list in support of persistent memory provisioning
support targeting v5.15.
The critical update from an enumeration perspective is support for the
CXL Fixed Memory Window Structure that indicates to Linux which system
physical address ranges decode to the CXL Host Bridges in the system.
This allows the driver to detect which address ranges have been mapped
by firmware and what address ranges are available for future hotplug.
So, again, mostly skeleton this round, with more meat targeting v5.15.
Summary:
- Add support for the CXL Fixed Memory Window Structure, a recent
extension of the ACPI CEDT (CXL Early Discovery Table)
- Add infrastructure for component registers
- Add HDM (Host-managed device memory) decoder definitions

- Added option for per CPU threads to the hwlat tracer
- Have hwlat tracer handle hotplug CPUs
- New tracer: osnoise, that detects latency caused by interrupts, softirqs
and scheduling of other tasks.
- Added timerlat tracer that creates a thread and measures in detail what
sources of latency it has for wake ups.
- Removed the "success" field of the sched_wakeup trace event.
This has been hardcoded as "1" since 2015, no tooling should be looking
at it now. If one exists, we can revert this commit, fix that tool and
try to remove it again in the future.
- tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.
- New boot command line option "tp_printk_stop", as tp_printk causes trace
events to write to console. When user space starts, this can easily live
lock the system. Having a boot option to stop just after boot up is
useful to prevent that from happening.
- Have ftrace_dump_on_oops boot command line option take numbers that match
the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.
- Bootconfig clean ups, fixes and enhancements.
- New ktest script that tests bootconfig options.
- Add tracepoint_probe_register_may_exist() to register a tracepoint
without triggering a WARN*() if it already exists. BPF has a path from
user space that can do this. All other paths are considered a bug.
- Small clean ups and fixes

As the diffstat scatters over the tree, we've got many tree-wide
small changes, but also got quite a few intrusive changes in the
core side. The only ABI-visible core change is the new rawmidi
framing mode support while others are kernel-internal, mostly code
refactoring and/or nice improvements.
Here are some highlights:
Core:
- A new framing access mode for rawmidi to get timestamps
- Cleanup / refactoring of buffer memory management helper code
- Support for automatic negotiation of ASoC DAI formats
- Revival of software suspend for PCM and control core, as a
preliminary work for PCI BAR rescan support
ASoC:
- Accessory detection support for several Qualcomm parts
- Support for IEC958 control with hdmi-codec
- Merging of Tegra machine drivers into a single driver
- Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP
i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm
Quinary MI2S, Texas Instruments TAS2505
USB-audio:
- Reduction of latency at playback start
- Code cleanup / fixes of usx2y driver
- Scarlett2 mixer code fixes and enhancements
- Quirks for Ozone and Denon devices
HD-audio:
- A few quirks for HP and ASUS machines
- Display power management fixes
Others:
- FireWire code refactoring and enhancements
- Tree-wide trivial coding-style fixes

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.

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,

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"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

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.

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.

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.

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.

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.

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.
We disable PMD mapping of vmemmap pages for x86-64 arch when this feature
is enabled. Because vmemmap_remap_free() depends on vmemmap being base
page mapped.

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.

an optional "metadata_only" feature that only promotes bios flagged

Commit e3c0623608 ("cpufreq: add cpufreq_driver_resolve_freq()")
introduced this callback, back in 2016, for drivers that provide the
->target() callback.
The kernel hasn't seen a single user of it in the past 5 years and
it is not likely to be used any time soon.
Remove it for now.

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"

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

- 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.

Merge tag 'printk-for-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Add %pt[RT]s modifier to vsprintf(). It overrides ISO 8601 separator
by using ' ' (space). It produces "YYYY-mm-dd HH:MM:SS" instead of
"YYYY-mm-ddTHH:MM:SS".
- Correctly parse long row of numbers by sscanf() when using the field
width. Add extensive sscanf() selftest.
- Generalize re-entrant CPU lock that has already been used to
serialize dump_stack() output. It is part of the ongoing printk
rework. It will allow to remove the obsoleted printk_safe buffers and
introduce atomic consoles.
- Some code clean up and sparse warning fixes.

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.
# grep -E "high:|batch" /proc/zoneinfo | tail -2
high: 649
batch: 63
# sysctl vm.percpu_pagelist_high_fraction=8
# grep -E "high:|batch" /proc/zoneinfo | tail -2

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.

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.

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.
