mm/memory_hotplug: add missing mem_hotplug_lock
From Documentation/core-api/memory-hotplug.rst: When adding/removing/onlining/offlining memory or adding/removing heterogeneous/device memory, we should always hold the mem_hotplug_lock in write mode to serialise memory hotplug (e.g. access to global/zone variables). mhp_(de)init_memmap_on_memory() functions can change zone stats and struct page content, but they are currently called w/o the mem_hotplug_lock. When memory block is being offlined and when kmemleak goes through each populated zone, the following theoretical race conditions could occur: CPU 0: | CPU 1: memory_offline() | -> offline_pages() | -> mem_hotplug_begin() | ... | -> mem_hotplug_done() | | kmemleak_scan() | -> get_online_mems() | ... -> mhp_deinit_memmap_on_memory() | [not protected by mem_hotplug_begin/done()]| Marks memory section as offline, | Retrieves zone_start_pfn poisons vmemmap struct pages and updates | and struct page members. the zone related data | | ... | -> put_online_mems() Fix this by ensuring mem_hotplug_lock is taken before performing mhp_init_memmap_on_memory(). Also ensure that mhp_deinit_memmap_on_memory() holds the lock. online/offline_pages() are currently only called from memory_block_online/offline(), so it is safe to move the locking there.

regmap: fix bogus error on regcache_sync success
Since commit 0ec7731655de ("regmap: Ensure range selector registers
are updated after cache sync") opening pcm512x based soundcards fail
with EINVAL and dmesg shows sync cache and pm_runtime_get errors:
[ 228.794676] pcm512x 1-004c: Failed to sync cache: -22
[ 228.794740] pcm512x 1-004c: ASoC: error at snd_soc_pcm_component_pm_runtime_get on pcm512x.1-004c: -22
This is caused by the cache check result leaking out into the
regcache_sync return value.
Fix this by making the check local-only, as the comment above the
regcache_read call states a non-zero return value means there's
nothing to do so the return value should not be altered.

devcoredump: Send uevent once devcd is ready
dev_coredumpm() creates a devcoredump device and adds it
to the core kernel framework which eventually end up
sending uevent to the user space and later creates a
symbolic link to the failed device. An application
running in userspace may be interested in this symbolic
link to get the name of the failed device.
In a issue scenario, once uevent sent to the user space
it start reading '/sys/class/devcoredump/devcdX/failing_device'
to get the actual name of the device which might not been
created and it is in its path of creation.
To fix this, suppress sending uevent till the failing device
symbolic link gets created and send uevent once symbolic
link is created successfully.

sysctl-6.7-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size
penalty sysctl has been changed to allow us to not require the sentinel, the
final empty element on the sysctl array. Joel Granados has been doing all this
work. On the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove
the sentinel. Both arch and driver changes have been on linux-next for a bit
less than a month. It is worth re-iterating the value:
- this helps reduce the overall build time size of the kernel and run time
memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move sysctls
out from kernel/sysctl.c to their own files
For v6.8-rc1 expect removal of all the sentinels and also then the unneeded
check for procname == NULL.
The last 2 patches are fixes recently merged by Krister Johansen which allow
us again to use softlockup_panic early on boot. This used to work but the
alias work broke it. This is useful for folks who want to detect softlockups
super early rather than wait and spend money on cloud solutions with nothing
but an eventual hung kernel. Although this hadn't gone through linux-next it's
also a stable fix, so we might as well roll through the fixes now.

The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware drivers.
- Arm FF-A firmware support gains support for v1.1 specification features,
in particular notification and memory transaction descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper.

regmap: prevent noinc writes from clobbering cache
Currently, noinc writes are cached as if they were standard incrementing
writes, overwriting unrelated register values in the cache. Instead, we
want to cache the last value written to the register, as is done in the
accelerated noinc handler (regmap_noinc_readwrite).

firmware_loader: Abort all upcoming firmware load request once reboot triggered
There could be following scenario where there is a ongoing reboot
is going from processA which tries to call all the reboot notifier
callback and one of them is firmware reboot call which tries to
abort all the ongoing firmware userspace request under fw_lock but
there could be another processB which tries to do request firmware,
which came just after abort done from ProcessA and ask for userspace
to load the firmware and this can stop the ongoing reboot ProcessA
to stall for next 60s(default timeout) which may not be expected
behaviour everyone like to see, instead we should abort any firmware
load request which came once firmware knows about the reboot through
notification.

regmap: Ensure range selector registers are updated after cache sync
When we sync the register cache we do so with the cache bypassed in order to avoid overhead from writing the synced values back into the cache. If the regmap has ranges and the selector register for those ranges is in a register which is cached this has the unfortunate side effect of meaning that the physical and cached copies of the selector register can be out of sync after a cache sync. The cache will have whatever the selector was when the sync started and the hardware will have the selector for the register that was synced last. Fix this by rewriting all cached selector registers after every sync, ensuring that the hardware and cache have the same content. This will result in extra writes that wouldn't otherwise be needed but is simple so hopefully robust. We don't read from the hardware since not all devices have physical read support. Given that nobody noticed this until now it is likely that we are rarely if ever hitting this case.

regmap: kunit: Add test for cache sync interaction with ranges
Hector Martin reports that since when doing a cache sync we enable cache bypass if the selector register for a range is cached then we might leave the physical selector register pointing to a different value to that which we have in the cache. If we then try to write to the page that our cache tells us is selected we will not update the selector register and write to the wrong page. Add a test case covering this.

mm, pcp: reduce lock contention for draining high-order pages
In commit f26b3fa04611 ("mm/page_alloc: limit number of high-order pages
on PCP during bulk free"), the PCP (Per-CPU Pageset) will be drained when
PCP is mostly used for high-order pages freeing to improve the cache-hot
pages reusing between page allocating and freeing CPUs.
On system with small per-CPU data cache slice, pages shouldn't be cached
before draining to guarantee cache-hot. But on a system with large
per-CPU data cache slice, some pages can be cached before draining to
reduce zone lock contention.
So, in this patch, instead of draining without any caching, "pcp->batch"
pages will be cached in PCP before draining if the size of the per-CPU
data cache slice is more than "3 * batch".
In theory, if the size of per-CPU data cache slice is more than "2 *
batch", we can reuse cache-hot pages between CPUs. But considering the
other usage of cache (code, other data accessing, etc.), "3 * batch" is
used.
Note: "3 * batch" is chosen to make sure the optimization works on recent
x86_64 server CPUs. If you want to increase it, please check whether it
breaks the optimization.
On a 2-socket Intel server with 128 logical CPU, with the patch, the

cacheinfo: calculate size of per-CPU data cache slice
This can be used to estimate the size of the data cache slice that can be used by one CPU under ideal circumstances. Both DATA caches and UNIFIED caches are used in calculation. So, the users need to consider the impact of the code cache usage. Because the cache inclusive/non-inclusive information isn't available now, we just use the size of the per-CPU slice of LLC to make the result more predictable across architectures. This may be improved when more cache information is available in the future. A brute-force algorithm to iterate all online CPUs is used to avoid to allocate an extra cpumask, especially in offline callback.

The generic PM domain is currently the only PM domain variant that supports performance scaling. To allow performance scaling to be supported through a common interface, let's add an optional callback ->set_performance_state(), in the struct dev_pm_domain. Moreover, let's add a function, dev_pm_domain_set_performance_state(), that may be called by consumers to request a new performance state for a device through its PM domain. Note that, in most cases it's preferred that a consumer use the OPP library to request a new performance state for its device.

regmap: rbtree: Fix wrong register marked as in-cache when creating new node
When regcache_rbtree_write() creates a new rbtree_node it was passing the
wrong bit number to regcache_rbtree_set_register(). The bit number is the
offset __in number of registers__, but in the case of creating a new block
regcache_rbtree_write() was not dividing by the address stride to get the
number of registers.
Fix this by dividing by map->reg_stride.
Compare with regcache_rbtree_read() where the bit is checked.
This bug meant that the wrong register was marked as present. The register
that was written to the cache could not be read from the cache because it
was not marked as cached. But a nearby register could be marked as having
a cached value even if it was never written to the cache.

The commit d21fdd07cea4 ("driver core: Return proper error code when

-EINVAL might be rewritten and hence the error path can't be triggered
at some circumstances. To fix this, make sure that error variable is
set to -EINVAL when other conditionals are false.

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

- 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

Devicetree updates for v6.6:
DT core:
- Add support for generating DT nodes for PCI devices. This is the
groundwork for applying overlays to PCI devices containing
non-discoverable downstream devices.
- DT unittest additions to check reverted changesets, to test for
refcount issues, and to test unresolved symbols. Also, various
clean-ups of the unittest along the way.
- Refactor node and property manipulation functions to better share code
with old API and changeset API
- Refactor changeset print functions to a common implementation
- Move some platform_device specific functions into of_platform.c
Bindings:
- Treewide fixing of typos
- Treewide clean-up of SPDX tags to use 'OR' consistently
- Last chunk of dropping unnecessary quotes. With that, the check
for unnecessary quotes is enabled in yamllint.
- Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
bindings to DT schema format
- Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450 Inline
Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt controller,
Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings
- Fixes for Rockchip DWC PCI binding
- Ensure all properties are evaluated on USB connector schema
- Fix dt-check-compatible script to find of_device_id instances with
compiler annotations
