Pull power management fixes from Rafael Wysocki:
"These fix two cpufreq issues, one in the core and one in the
conservative governor, and two issues related to system sleep:
- Restore the cpufreq core behavior changed inadvertently during the
6.19 development cycle to call cpufreq_frequency_table_cpuinfo()
for cpufreq policies getting re-initialized which ensures that
policy->max and policy->cpuinfo_max_freq will be valid going
forward (Viresh Kumar)
- Adjust the cached requested frequency in the conservative cpufreq
governor on policy limits changes to prevent it from becoming stale
in some cases (Viresh Kumar)
- Prevent pm_restore_gfp_mask() from triggering a WARN_ON() in some
code paths in which it is legitimately called without invoking
pm_restrict_gfp_mask() previously (Youngjun Park)

[scudo] Add Last entry to ReleaseToOS enum. (#188645)
This allows static asserts to be set in tracing code that might use the
ReleaseToOS values as indexes.
This would have caused a compile failure instead of a runtime crash when
I added the use of a new ReleaseToOS value.

ftp/curl: Fix build on FreeBSD 13
- Update OPTIONS_DEFAULT:
- Change from OPENSSL to OPENSSL
- Remove LIBSSH2 and TLS_SRP (depends on OPENSSL)
ftp/curl uses OpenSSL by default. However, curl 8.18.0 drops OpenSSL 1.x support
which is used in FreeBSD 13 base system. Therefore, we change the defaults to
wolfSSL instead. This commit can be reverted after FreeBSD 13 EoL (expected Apr
30, 2026).
[InstCombine] Fold `fcmp (C - [su]itofp X), C` to integer compares (#185826)
Recognize `fcmp pred (C - [su]itofp X), C` in InstCombine and fold it to
`fcmp swap(pred) [su]itofp X, 0` for certain constant `C` (to make sure
`C - Y` nevers rounds back to `C`), then the new pattern further can be
folded by `foldFCmpIntToFPConst` to integer compares.
Fixes #185561

alive2 with constant constraints (needs local alive2 build):
https://alive2.llvm.org/ce/z/wDs9Tj
I tried generalizing the pattern to any `fcmp pred, (C - Y), C` but
alive2 says no: https://alive2.llvm.org/ce/z/qMLGah. So I will try to
find more constraints on C and Y to make this rewrite hold in future
PRs.
[libc++] Add another const_cast to support hash_map copy assignment
There was one more const_cast needed after #183223 without which
copy assignment of hash_map was broken. Add it, together with a copy

[VPlan] Expose cloneFrom and mergeBlocksIntoPredecessors. (NFC) (#188818)
Move cloneFrom from a file-static function in VPlan.cpp to a public
static method VPBlockUtils::cloneFrom, and move
mergeBlocksIntoPredecessors from a file-static function in
VPlanTransforms.cpp to a public static method
VPlanTransforms::mergeBlocksIntoPredecessors.
This is in preparation for dissolving replicate regions which needs both

[VPlan] Extract addLaneToStartIndex helper from cloneForLane. (NFC) (#188819)

x86: Handle when MPERF/APERF MSRs aren't writable
For performance and/or correct reasons some hypervisors allow
MPERF/APERF MSRs to be read but not written to. This change
modifies the handling of these MSRs to not rely on writes.

In the case where the record in an Init List expression is a prvalue
create an xvalue so member accesses will be xvalues. This is in line
with the C++ specification. The Clang code which generates the member
field access however does not create an xvalue if the record is a
prvalue, so we make the record an xvalue here.

[libc++] Fix negate and bit_xor in C++03 frozen headers (#187573)
An unintended change in #134045 gave them a default template argument,
which is supposed to be from C++14 onwards.
I considered adding a test for this but it is really awkward to test
that we don't support passing no template argument in C++03 mode and
that provides little value, so I decided against it.
[flang][cuda] Use walk instead of getOps to process nested cuf.shared_memory ops (#188812)
The CUFComputeSharedMemoryOffsetsAndSize pass used getOps to find
cuf.shared_memory operations, which only searches direct children of
gpu.func. When cuf.shared_memory ops are nested inside scf.parallel
(e.g. from reduction lowering), they are missed and never receive
offset/isStatic attributes, causing a "cuf.shared_memory must have an
offset for code gen" assertion later. Switch to walk to find
cuf.shared_memory ops at any nesting depth.
