Re-introduce kern.sched.topology_spec
Move it back from kern.sched.ule.topology_spec.
Make it scheduler-agnostic.
Provide trivial report for UP kernels.
Apparently the MIB is used by some third-party software. Obviously it
did not worked on UP or 4BSD configs.

readfirstlane can be moved across control flow for uniform inputs.
The MachineInstr::NoConvergent attribute allows hoisting
which is otherwise prohibited for a convergent instruction.

[AMDGPU] Return two MMOs for load-to-lds and store-from-lds intrinsics
Accurately represent both the load and the store part of those
intrinsics.
The test changes seem to be mostly fairly insignificant changes caused by
subtly different scheduler behavior.

[AMDGPU] Add scheduling DAG mutation for hazard latencies (#170075)
Improve waitcnt merging in ML kernel loops by increasing latencies on
VALU writes to SGPRs.
Specifically this helps with the case of V_CMP output feeding V_CNDMASK
instructions.
acpi: add Darwin OSI quirk for Apple Mac hardware
Mac firmware hides the Intel integrated GPU (iGPU) on dual GPU x86
systems, i.e., with AMD/NVIDIA dGPUs, when the Darwin OSI is not
installed via ACPI.
Prior to this change, FreeBSD always used the dGPU. This is fine in
practice, but consumed more power than when the iGPU is used,
resulting in reduced battery life.
Linux handles this in `drivers/acpi/osi.c` by detecting Apple
hardware via DMI, disabling all Windows OSI strings, and
by explicitly installing the Darwin OSI ACPI handler. This change
applies equivalent logic to the acpi(4) driver on FreeBSD.
This feature can be enabled/disabled using the
`hw.acpi.apple_darwin_osi` tunable. Setting this tunable to `0`
restores the previous behavior by explicitly disabling the added
support.

[CodeGen] Refactor targets to override the new getTgtMemIntrinsic overload (NFC) (#175844)
This is a fairly mechanical change. Instead of returning true/false,
we either keep the Infos vector empty or push one entry.

[compiler-rt][common] Don't unmap stacks not mapped by the runtime
When the sanitizer hasn't mapped the alternate signal stack, but the
host program has (like LLVM), the runtime still tries to unilaterally
unmap the alternate stack. Instead, the runtime should just check if
it's actually mmaped the alternate stack, and only unmap it if it has.
workflows/commit-access-review: Use a GitHub App access token instead of llvmbot
This replaces the use of an access token associated with the llvmbot
account with one that is generated by a GitHub App. This is slightly
better, because it eliminates the need to periodically rotate the
llvmbot tokens, which is difficult to do, since it requires sharing
a password and 2fa code among all the admins.
The tokens generated by the app automatically expire after an hour, and
the private key that is used to request it can be easily rotated by
an LLVM Organization owner. Also, since a single private key can
be used to generate many tokens, there is only one secret to rotate
instead of many.
[InstCombine] Preserve fdiv metadata on fneg folds (#179157)
Copy metadata from the original fdiv when folding fneg into fdiv or
hoisting fneg above fdiv. This keeps !fpmath (and other metadata)
intact, preventing !fpmath loss seen in libclc tanpi function. fneg only
flips sign bit, so it does not affect precision.
[clang-tidy][NFC] Fix incorrect `list.rst` modification by `add_new_check.py` (#179297)
We have observed unexpected and extensive modifications to `list.rst` in
a few Pull Requests. After some investigation I found that
`add_new_check.py` was misclassifying existing checks, leading to
instability in the generated documentation list.
More specifically:
- The script relies on `http-equiv=refresh` meta tags to identify alias
checks, which is missing in several existing checks, causing them to be
incorrectly listed as regular checks.
- The script fails to detect fix-its in checks that use CamelCase helper
methods.
With this patch, running `add_new_check.py` now generates a stable and
correct `list.rst` consistent with the actual codebase state.
