[mlir][ODS] Share operation interface methods with raw-op bodies (NFC) (#226317)
Allow an operation interface method to use a shared callback when its
body only needs the raw Operation. Use it for OpenMP block-argument
indexing and slicing methods, avoiding per-operation wrappers while
preserving the existing fallback and external model paths.
Reduces the size of the OpenMP dialect text section by 1.68%.

[bazel] Download linux UAPI headers when no local dir is set (#216868)
This PR defines a hermetic source for `@linux_api//:linux_uapi_headers`
that will be used in CI. If no `LINUX_UAPI_INCLUDE_DIR` value is
specified, then Bazel will download the linux-libc-dev debian package
and use its headers.
I originally wanted to pull from https://github.com/torvalds/linux and
build UAPI headers from source as it gives more control, but the repo is
rather large and took ~20s to download and ~10s to build. Using the
debian package's headers is closer to what the LLVM-libc fullbuild CI
[currently
does](https://github.com/llvm/llvm-project/blob/007551bacb899a409218574908d96b0633d52018/.github/workflows/containers/libc/Dockerfile#L38)
and is very fast.
[LLVM] Use complete runtime dependency list for multilibs (#226580)
Summary:
The current handling makes the multilib job depend on the base runtimes
job. This means that we will potentially depend on things that don't
necessarily need to be built to fulfil the multilibs job. Instead, just
depend on the individual targets for that multilib.
nvme: collapse the per-counter qpair statistic sysctl handlers

nvmf: factor out the pending request abort loop
The routine is entered with the namespace lock held and drops it before

sysvshm: Fix locking in shm_prison_set()
We were not acquiring the global sysvshm lock when handling cleanup of
sysvshm segments. Acquire the lock in shm_prison_cleanup() instead, to
be consistent with the sysv semaphore code.

[TBAA] Recover !tbaa for a memcpy of struct with same type fields (#214116)
When InstCombine widens a small same-typed aggregate copy into an
integer load/store, it derives no !tbaa, and !tbaa.struct is nulled out,
so the load/store are left untyped. An untyped access may-alias every
typed access and blocks optimization:
struct Coord { int x, y; };
void copy_if_inbounds(Coord *dst, const Coord *src, const long *bound,
int n) {
for (int i = 0; i < n; ++i)
if (i < *bound)
dst[i] = *src; // {int,int} copy -> memcpy + !tbaa.struct
}
compare this to field-by-field copy, which has typed field access
void copy_fields_if_inbounds(Coord *dst, const Coord *src, const long
*bound, int n) {
for (int i = 0; i < n; ++i)

multimedia/jellyfin-ffmpeg: opencl needed for Jellyfin's HDR tone mapping
Jellyfin does AMD VAAPI HDR tone mapping with libplacebo, not OpenCL. However,
EncodingHelper.GetVaapiVidFilterChain() has an early-exit guard before it ever
selects the AMD branch
It need 2 patches:
- OpenCL (Jellyfin's IsOpenclFullSupported gate)
- overlay_vulkan framesync patch (Jellyfin's IsVulkanFullSupported gate)

[Clang] Enforce the same size limits for `vector_size` and `ext_vector_type` (#226375)
Fixes #165458
A `bool` vector declared with `ext_vector_type` isn't lowered as an LLVM
vector in memory: `ConvertTypeForMem` packs it into a single integer
with one bit per element. `BuildExtVectorType` only checked that the
element count fits in 32 bits, though, so a vector of 187,553,262 bools
got through Sema and the first consumer that needed its memory type (the
zero initializer of a tentative definition here) asked
`IntegerType::get` for far more than the 2^23 bits it supports. The
count matters for every element type, not just `bool`, because Sema also
forms bool vectors out of other vectors (`c ? true : false` with a
`char` vector condition), and `vector_size` was no better off with its
limits of 2^32 elements and 2^61 bytes.
Both attributes now go through the same two limits when the type is
built, reusing the existing "vector size too large" error: at most
`llvm::IntegerType::MAX_INT_BITS` (2^23) elements, and at most 2^28
