Pull power management updates from Rafael Wysocki:
 "These are mostly cpufreq updates, including a significant intel-pstate
  driver update and several amd-pstate improvements plus some updates of
  ARM cpufreq drivers, general fixes and cleanups.

  Also included are changes related to system sleep, power capping
  updates adding support for a new platform and a new hardware feature
  (among other things), a Samsung exynos-asv driver update allowing it
  to change its Energy Model after adjusting voltage, minor cpuidle and
  devfreq updates and a small documentation cleanup.

  Specifics:

   - Rework the handling of disabled turbo in the intel_pstate driver
     and make it update the maximum CPU frequency consistently
     regardless of the reason on top of a number of cleanups (Rafael
     Wysocki)

   - Add missing checks for NULL .exit() cpufreq driver callback to the
     cpufreq core (Viresh Kumar)

   - Prevent pulicy-&gt;max from going above the frequency QoS maximum
     value when cpufreq_frequency_table_verify() is used (Xuewen Yan)

   - Prevent a negative CPU number or frequency value from being printed
     if they are really large (Joshua Yeong)

   - Update MAINTAINERS entry for amd-pstate to add two new
     submaintainers and a designated reviewer (Huang Rui)

   - Clean up the amd-pstate driver and update its documentation
     (Gautham Shenoy)

   - Fix the highest frequency issue in the amd-pstate driver which
     limits performance (Perry Yuan)

   - Enable CPPC v2 for certain processors in the family 17H, as
     requested by TR40 processor users who expect improved performance
     and lower system temperature (Perry Yuan)

   - Change latency and delay values to be read from platform firmware
     firstly for more accurate timing (Perry Yuan)

   - A new quirk is introduced for supporting amd-pstate on legacy
     processors which either lack CPPC capability, or only only have
     CPPC v2 capability (Perry Yuan)

   - Sun50i cpufreq: Add support for opp_supported_hw, H616 platform and
     general cleanups (Andre Przywara, Martin Botka, Brandon Cheo Fusi,
     Dan Carpenter, Viresh Kumar)

   - CPPC cpufreq: Fix possible null pointer dereference (Aleksandr
     Mishin)

   - Eliminate uses of of_node_put() from cpufreq (Javier Carrasco,
     Shivani Gupta)

   - brcmstb-avs: ISO C90 forbids mixed declarations (Portia Stephens)

   - mediatek cpufreq: Add support for MT7988A (Sam Shih)

   - cpufreq-qcom-hw: Add SM4450 compatibles in DT bindings (Tengfei
     Fan)

   - Fix struct cpudata::epp_cached kernel-doc in the intel_pstate
     cpufreq driver (Jeff Johnson)

   - Fix kerneldoc description of ladder_do_selection() (Jeff Johnson)

   - Convert the cpuidle kirkwood driver to platform remove callback
     returning void (Yangtao Li)

   - Replace deprecated strncpy() with strscpy() in the hibernation core
     code (Justin Stitt)

   - Use %ps to simplify debug output in the core system-wide suspend
     and resume code (Len Brown)

   - Remove unnecessary else from device_init_wakeup() and make
     device_wakeup_disable() return void (Dhruva Gole)

   - Enable PMU support in the Intel TPMI RAPL driver (Zhang Rui)

   - Add support for ArrowLake-H platform to the Intel RAPL driver
     (Zhang Rui)

   - Avoid explicit cpumask allocation on stack in DTPM (Dawei Li)

   - Make the Samsung exynos-asv driver update the Energy Model after
     adjusting voltage on top of some preliminary changes of the OPP and
     Enery Model generic code (Lukasz Luba)

   - Remove a reference to a function that has been dropped from the
     power management documentation (Bjorn Helgaas)

   - Convert the platfrom remove callback to .remove_new for the
     exyno-nocp, exynos-ppmu, mtk-cci-devfreq, sun8i-a33-mbus, and
     rk3399_dmc devfreq drivers (Uwe Kleine-König)

   - Use DEFINE_SIMPLE_PM_OPS for exyno-bus.c driver (Anand Moon)"

In general it's preferable to avoid placing cpumasks on the stack, as
for large values of NR_CPUS these can consume significant amounts of
stack space and make stack overflows more likely.

Use cpumask_first_and_and() and cpumask_weight_and() to avoid the need
for a temporary cpumask on the stack.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Clients like regulators, interconnects and clocks depend on rpmh-rsc to
vote on resources and rpmh-rsc depends on psci power-domains to complete
probe. All of them are in core_initcall().

Change psci domain init level to core_initcall() to avoid probe defer from

To support ACPI Low Power Idle (LPI), few functions are required which
are currently static functions in the DT based cpuidle driver. Hence,
move them under arch/riscv so that ACPI driver also can use them. Since
they are no longer static functions, append "riscv_" prefix to the
function name.

Pull MM updates from Andrew Morton:

 - Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
   from hotplugged memory rather than only from main memory. Series
   "implement "memmap on memory" feature on s390".

 - More folio conversions from Matthew Wilcox in the series

	"Convert memcontrol charge moving to use folios"
	"mm: convert mm counter to take a folio"

 - Chengming Zhou has optimized zswap's rbtree locking, providing
   significant reductions in system time and modest but measurable
   reductions in overall runtimes. The series is "mm/zswap: optimize the
   scalability of zswap rb-tree".

 - Chengming Zhou has also provided the series "mm/zswap: optimize zswap
   lru list" which provides measurable runtime benefits in some
   swap-intensive situations.

 - And Chengming Zhou further optimizes zswap in the series "mm/zswap:
   optimize for dynamic zswap_pools". Measured improvements are modest.

 - zswap cleanups and simplifications from Yosry Ahmed in the series
   "mm: zswap: simplify zswap_swapoff()".

 - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
   contributed several DAX cleanups as well as adding a sysfs tunable to
   control the memmap_on_memory setting when the dax device is
   hotplugged as system memory.

 - Johannes Weiner has added the large series "mm: zswap: cleanups",
   which does that.

 - More DAMON work from SeongJae Park in the series

	"mm/damon: make DAMON debugfs interface deprecation unignorable"
	"selftests/damon: add more tests for core functionalities and corner cases"
	"Docs/mm/damon: misc readability improvements"
	"mm/damon: let DAMOS feeds and tame/auto-tune itself"

 - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
   extension" Rakie Kim has developed a new mempolicy interleaving
   policy wherein we allocate memory across nodes in a weighted fashion
   rather than uniformly. This is beneficial in heterogeneous memory
   environments appearing with CXL.

 - Christophe Leroy has contributed some cleanup and consolidation work
   against the ARM pagetable dumping code in the series "mm: ptdump:
   Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".

 - Luis Chamberlain has added some additional xarray selftesting in the
   series "test_xarray: advanced API multi-index tests".

 - Muhammad Usama Anjum has reworked the selftest code to make its
   human-readable output conform to the TAP ("Test Anything Protocol")
   format. Amongst other things, this opens up the use of third-party
   tools to parse and process out selftesting results.

 - Ryan Roberts has added fork()-time PTE batching of THP ptes in the
   series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
   targeted at arm64, this significantly speeds up fork() when the
   process has a large number of pte-mapped folios.

 - David Hildenbrand also gets in on the THP pte batching game in his
   series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
   implements batching during munmap() and other pte teardown
   situations. The microbenchmark improvements are nice.

 - And in the series "Transparent Contiguous PTEs for User Mappings"
   Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte
   mappings"). Kernel build times on arm64 improved nicely. Ryan's
   series "Address some contpte nits" provides some followup work.

 - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
   fixed an obscure hugetlb race which was causing unnecessary page
   faults. He has also added a reproducer under the selftest code.

 - In the series "selftests/mm: Output cleanups for the compaction
   test", Mark Brown did what the title claims.

 - Kinsey Ho has added the series "mm/mglru: code cleanup and
   refactoring".

 - Even more zswap material from Nhat Pham. The series "fix and extend
   zswap kselftests" does as claimed.

 - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
   regression" Mathieu Desnoyers has cleaned up and fixed rather a mess
   in our handling of DAX on archiecctures which have virtually aliasing
   data caches. The arm architecture is the main beneficiary.

 - Lokesh Gidra's series "per-vma locks in userfaultfd" provides
   dramatic improvements in worst-case mmap_lock hold times during
   certain userfaultfd operations.

 - Some page_owner enhancements and maintenance work from Oscar Salvador
   in his series

	"page_owner: print stacks and their outstanding allocations"
	"page_owner: Fixup and cleanup"

 - Uladzislau Rezki has contributed some vmalloc scalability
   improvements in his series "Mitigate a vmap lock contention". It
   realizes a 12x improvement for a certain microbenchmark.

 - Some kexec/crash cleanup work from Baoquan He in the series "Split
   crash out from kexec and clean up related config items".

 - Some zsmalloc maintenance work from Chengming Zhou in the series

	"mm/zsmalloc: fix and optimize objects/page migration"
	"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"

 - Zi Yan has taught the MM to perform compaction on folios larger than
   order=0. This a step along the path to implementaton of the merging
   of large anonymous folios. The series is named "Enable &gt;0 order folio
   memory compaction".

 - Christoph Hellwig has done quite a lot of cleanup work in the
   pagecache writeback code in his series "convert write_cache_pages()
   to an iterator".

 - Some modest hugetlb cleanups and speedups in Vishal Moola's series
   "Handle hugetlb faults under the VMA lock".

 - Zi Yan has changed the page splitting code so we can split huge pages
   into sizes other than order-0 to better utilize large folios. The
   series is named "Split a folio to any lower order folios".

 - David Hildenbrand has contributed the series "mm: remove
   total_mapcount()", a cleanup.

 - Matthew Wilcox has sought to improve the performance of bulk memory
   freeing in his series "Rearrange batched folio freeing".

 - Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
   provides large improvements in bootup times on large machines which
   are configured to use large numbers of hugetlb pages.

 - Matthew Wilcox's series "PageFlags cleanups" does that.

 - Qi Zheng's series "minor fixes and supplement for ptdesc" does that
   also. S390 is affected.

 - Cleanups to our pagemap utility functions from Peter Xu in his series
   "mm/treewide: Replace pXd_large() with pXd_leaf()".

 - Nico Pache has fixed a few things with our hugepage selftests in his
   series "selftests/mm: Improve Hugepage Test Handling in MM
   Selftests".

 - Also, of course, many singleton patches to many things. Please see
   the individual changelogs for details.
