ACPI: RISC-V: Fix FFH_CPPC_CSR error handling
The cppc_ffh_csr_read() and cppc_ffh_csr_write() returns Linux error
code in "data->ret.error" so cpc_read_ffh() and cpc_write_ffh() must
not use sbi_err_map_linux_errno() for FFH_CPPC_CSR.

ACPI/IORT: Fix memory leak in iort_rmr_alloc_sids()
If krealloc_array() fails in iort_rmr_alloc_sids(), the function returns
NULL but does not free the original 'sids' allocation. This results in a
memory leak since the caller overwrites the original pointer with the
NULL return value.

ACPI: pfr_update: Fix the driver update version check
The security-version-number check should be used rather
than the runtime version check for driver updates.
Otherwise, the firmware update would fail when the update binary had
a lower runtime version number than the current one.

ACPI: APEI: EINJ: Fix resource leak by remove callback in .exit.text
The .remove() callback is also used during error handling in
faux_probe(). As einj_remove() was marked with __exit it's not linked
into the kernel if the driver is built-in, potentially resulting in
resource leaks.
Also remove the comment justifying the __exit annotation which doesn't
apply any more since the driver was converted to the faux device
interface.

ACPI: APEI: EINJ: fix potential NULL dereference in __einj_error_inject()
The __einj_error_inject() function allocates memory via kmalloc()
without checking for allocation failure, which could lead to a
NULL pointer dereference.
Return -ENOMEM in case allocation fails.

ACPI: APEI: EINJ: Check if user asked for EINJV2 injection
On an EINJV2 capable system, users may still use the old injection
interface but einj_get_parameter_address() takes the EINJV2 path to map
the parameter structure. This results in the address the user supplied
being stored to the wrong location and the BIOS injecting based on an
uninitialized field (0x0 in the reported case).
Check the version of the request when mapping the EINJ parameter
structure in BIOS reserved memory.

ACPI: EC: Relax sanity check of the ECDT ID string
It turns out that the ECDT table inside the ThinkBook 14 G7 IML
contains a valid EC description but an invalid ID string
("_SB.PC00.LPCB.EC0"). Ignoring this ECDT based on the invalid
ID string prevents the kernel from detecting the built-in touchpad,
so relax the sanity check of the ID string and only reject ECDTs
with empty ID strings.

Summary of significant series in this pull request:
- The 4 patch series "mm: ksm: prevent KSM from breaking merging of new

practical access monitoring" from SeongJae Park adds a new kernel module
which simplifies the setup and usage of DAMON in production
environments.

memset+mremap+munmap microbenchmark.
- The 5 patch series "Remove zero_user()" from Matthew Wilcox expunges
zero_user() in favor of the more modern memzero_page().
- The 3 patch series "mm/huge_memory: vmf_insert_folio_*() and
vmf_insert_pfn_pud() fixes" from David Hildenbrand addresses some warts
which David noticed in the huge page code. These were not known to be
causing any issues at this time.
- The 3 patch series "mm/damon: use alloc_migrate_target() for
DAMOS_MIGRATE_{HOT,COLD" from SeongJae Park provides some cleanup and
consolidation work in DAMON.

type" from Alistair Popple removes several now-unneeded PFN_* flags.
- The 5 patch series "mm/damon: decouple sysfs from core" from SeongJae
Park implememnts some cleanup and maintainability work in the DAMON
sysfs layer.

Previously these were lumped under the more general memory on/offline
notifier.
- The 6 patch series "Make MIGRATE_ISOLATE a standalone bit" from Zi Yan
cleans up the pageblock isolation code and fixes a potential issue which
doesn't seem to cause any problems in practice.
- The 5 patch series "selftests/damon: add python and drgn based DAMON
sysfs functionality tests" from SeongJae Park adds additional drgn- and
python-based DAMON selftests which are more comprehensive than the
existing selftest suite.
- The 5 patch series "Misc rework on hugetlb faulting path" from Oscar
Salvador fixes a rather obscure deadlock in the hugetlb fault code and
follows that fix with a series of cleanups.
- The 3 patch series "cma: factor out allocation logic from
__cma_declare_contiguous_nid" from Mike Rapoport rationalizes and cleans

SeongJae Park does that.
- The 6 patch series "mm/damon: misc cleanups" from SeongJae Park also
does what it claims.
- The 4 patch series "mm: folio_pte_batch() improvements" from David
Hildenbrand cleans up the large folio PTE batching code.
- The 13 patch series "mm/damon/vaddr: Allow interleaving in
migrate_{hot,cold} actions" from SeongJae Park facilitates dynamic
alteration of DAMON's inter-node allocation policy.
- The 3 patch series "Remove unmap_and_put_page()" from Vishal Moola
provides a couple of page->folio conversions.
- The 4 patch series "mm: per-node proactive reclaim" from Davidlohr
Bueso implements a per-node control of proactive reclaim - beyond the
current memcg-based implementation.
- The 14 patch series "mm/damon: remove damon_callback" from SeongJae
Park replaces the damon_callback interface with a more general and
powerful damon_call()+damos_walk() interface.
- The 10 patch series "mm/mremap: permit mremap() move of multiple VMAs"
from Lorenzo Stoakes implements a number of mremap cleanups (of course)
in preparation for adding new mremap() functionality: newly permit the
remapping of multiple VMAs when the user is specifying MREMAP_FIXED. It
still excludes some specialized situations where this cannot be
performed reliably.
- The 3 patch series "drop hugetlb_free_pgd_range()" from Anthony Yznaga
switches some sparc hugetlb code over to the generic version and removes
the thus-unneeded hugetlb_free_pgd_range().
- The 4 patch series "mm/damon/sysfs: support periodic and automated
stats update" from SeongJae Park augments the present
userspace-requested update of DAMON sysfs monitoring files. Automatic
update is now provided, along with a tunable to control the update
interval.
- The 4 patch series "Some randome fixes and cleanups to swapfile" from
Kemeng Shi does what is claims.
- The 4 patch series "mm: introduce snapshot_page" from Luiz Capitulino
and David Hildenbrand provides (and uses) a means by which debug-style
functions can grab a copy of a pageframe and inspect it locklessly
without tripping over the races inherent in operating on the live
pageframe directly.
- The 6 patch series "use per-vma locks for /proc/pid/maps reads" from
Suren Baghdasaryan addresses the large contention issues which can be
triggered by reads from that procfs file. Latencies are reduced by more
than half in some situations. The series also introduces several new
selftests for the /proc/pid/maps interface.
- The 6 patch series "__folio_split() clean up" from Zi Yan cleans up
__folio_split()!
- The 7 patch series "Optimize mprotect() for large folios" from Dev
Jain provides some quite large (>3x) speedups to mprotect() when dealing
with large folios.
- The 2 patch series "selftests/mm: reuse FORCE_READ to replace "asm
volatile("" : "+r" (XXX));" and some cleanup" from wang lian does some
cleanup work in the selftests code.
- The 3 patch series "tools/testing: expand mremap testing" from Lorenzo
Stoakes extends the mremap() selftest in several ways, including adding
more checking of Lorenzo's recently added "permit mremap() move of
multiple VMAs" feature.
- The 22 patch series "selftests/damon/sysfs.py: test all parameters"
from SeongJae Park extends the DAMON sysfs interface selftest so that it
tests all possible user-requested parameters. Rather than the present
minimal subset.

Pull power management updates from Rafael Wysocki:
"As is tradition, cpufreq is the part with the largest number of
updates that include core fixes and cleanups as well as updates of
several assorted drivers, but there are also quite a few updates
related to system sleep, mostly focused on asynchronous suspend and
resume of devices and on making the integration of system suspend
and resume with runtime PM easier.
Runtime PM is also updated to allow some code duplication in drivers
to be eliminated going forward and to work more consistently overall
in some cases.
Apart from that, there are some driver core updates related to PM
domains that should help to address ordering issues with devm_ cleanup
routines relying on PM domains, some assorted devfreq updates
including core fixes and cleanups, tooling updates, and documentation
and MAINTAINERS updates.

ACPI: processor: perflib: Fix initial _PPC limit application
If the BIOS sets a _PPC frequency limit upfront, it will fail to take
effect due to a call ordering issue. Namely, freq_qos_update_request()
is called before freq_qos_add_request() for the given request causing
the constraint update to be ignored. The call sequence in question is
as follows:
cpufreq_policy_online()
acpi_cpufreq_cpu_init()
acpi_processor_register_performance()
acpi_processor_get_performance_info()
acpi_processor_get_platform_limit()
freq_qos_update_request(&perflib_req) <- inactive QoS request
blocking_notifier_call_chain(&cpufreq_policy_notifier_list,
CPUFREQ_CREATE_POLICY)
acpi_processor_notifier()
acpi_processor_ppc_init()
freq_qos_add_request(&perflib_req) <- QoS request activation
Address this by adding an acpi_processor_get_platform_limit() call
to acpi_processor_ppc_init(), after the perflib_req activation via
freq_qos_add_request(), which causes the initial _PPC limit to be
picked up as appropriate. However, also ensure that the _PPC limit
will not be picked up in the cases when the cpufreq driver does not
call acpi_processor_register_performance() by adding a pr->performance
check to the related_cpus loop in acpi_processor_ppc_init().

ACPI: APEI: handle synchronous exceptions in task work
The memory uncorrected error could be signaled by asynchronous interrupt
(specifically, SPI in arm64 platform), e.g. when an error is detected by
a background scrubber, or signaled by synchronous exception
(specifically, data abort exception in arm64 platform), e.g. when a CPU
tries to access a poisoned cache line. Currently, both synchronous and
asynchronous errors use memory_failure_queue() to schedule
memory_failure() to exectute in a kworker context.
As a result, when a user-space process is accessing a poisoned data, a
data abort is taken and the memory_failure() is executed in the kworker
context, which:
- will send wrong si_code by SIGBUS signal in early_kill mode, and
- can not kill the user-space in some cases resulting a synchronous
error infinite loop
Issue 1: send wrong si_code in early_kill mode
Since commit

ACPI: APEI: send SIGBUS to current task if synchronous memory error not recovered
If a synchronous error is detected as a result of user-space process triggering a 2-bit uncorrected error, the CPU will take a synchronous error exception such as Synchronous External Abort (SEA) on Arm64. The kernel will queue a memory_failure() work which poisons the related page, unmaps the page, and then sends a SIGBUS to the process, so that a system wide panic can be avoided. However, no memory_failure() work will be queued when abnormal synchronous errors occur. These errors can include situations like invalid PA, unexpected severity, no memory failure config support, invalid GUID section, etc. In such a case, the user-space process will trigger SEA again. This loop can potentially exceed the platform firmware threshold or even trigger a kernel hard lockup, leading to a system reboot. Fix it by performing a force kill if no memory_failure() work is queued for synchronous errors.
