openssh: Move back UseBlocklist to global config
Revert UseBlocklist from SSHCFG_ALL to SSHCFG_GLOBAL (with
SSHCFG_COPY_NONE), ensuring it can only be set globally in sshd_config
rather than within conditional Match blocks, matching historical
behavior.

libpmc: userland support and pmc.rapl.3 for the RAPL class
Register PMC_CLASS_RAPL in libpmc: event table, allocator, class-table
descriptor, and the event-name/class-listing lookups, all x86-guarded
and modeled on the TSC class. Energy events are read-only and
unqualified. The class prefix (RAPL-) supplies the friendly spelling, so
pmcstat -S rapl-energy-pkg resolves to the canonical ENERGY_PKG event.
Add a pmc.rapl.3 manual page documenting the events, counter scope, the
microjoule unit and wrap handling, and the NUMA/package domain mapping;
link it from pmc.3.

hwpmc: add RAPL energy-counter class (AMD + Intel)
Add hwpmc_rapl.c/.h implementing PMC_CLASS_RAPL, a read-only
system-scope class modeled on TSC and wired into x86 AMD and Intel MD
init. A per-vendor MSR table covers AMD/Hygon and Intel; energy is
reported in microjoules, with the Intel server 2^-16 J DRAM unit
handled and 32-bit wraps recovered into a 64-bit accumulator.
The overflow guard follows the PMC lifetime: armed on the first
allocated PMC, callout_drain()d on the last release, and each tick only
rendezvouses CPUs holding one. Per-CPU spin locks guard the accumulator
against torn reads on i386. PMC_CAP_DOMWIDE lets pmcstat(8) allocate
one counter per NUMA domain instead of per CPU.

x86: add AMD RAPL MSR definitions to specialreg.h
specialreg.h is the tree's MSR registry and already carries the Intel

Use the names Linux's msr-index.h gives these registers.

[libunwind][PPC64] Fix unw_getcontext corrupting callee-saved VSX registers on LE (#198371)
This is the first of two independent fixes for libunwind on ppc64le
(ELFv2 ABI, little-endian), where two separate bugs together cause
SIGSEGV during backtracing. This commit addresses the VSX register
corruption; the TOC-restore fault is handled in a follow-up. Both
were discovered while debugging lang/rust build failures with
RUST_BACKTRACE=1 on FreeBSD/powerpc64le (IBM POWER9).
On ppc64le, `unw_getcontext` saves each VS register with an in-place
`xxswapd n, n` followed by `stxvd2x`. The swap is needed because
`stxvd2x` stores doublewords in the wrong order on LE. However, the
macro never applies a second `xxswapd` to restore the register after
the store, so all 64 VS registers are permanently corrupted on return
from `unw_getcontext`.
This affects every callee-saved VSX register: f14-f31 (VSR14-VSR31)

arm64: Use the fault handler when one is provided
In align_abort() and tag_check_abort(), if we got a fault while in kernel,
do not panic if a fault handler has been provided. We may get such a fault
when trying to read or write userland data, it can at least happen with
_umtx_op() if an unaligned pointer is provided. Instead, just let the
fault handler deal with it.
