Add middleware support for LIO ALUA HA
Wire up the middleware side of LIO ALUA high-availability: load
lio_ha.ko with per-node addresses on service start, manage ALUA
state across failover events, clean up STANDBY configfs on pool
export, and add pre-flight validation that targets have static
initiator ACLs before ALUA can be enabled.
For each target, create a portal-less phantom TPG carrying the peer
node's controller group so that a single RTPG response from any
connected port lists both ALUA groups. Write tpgt_N/rtpi explicitly
before enable so that relative target port IDs in RTPG match the
tag formula (portal.tag on Node A, portal.tag + 32000 on Node B)
rather than being auto-assigned sequentially by the kernel.
ALUA group states are driven by role and ha_state:
MASTER + synced local=OPTIMIZED remote=NONOPTIMIZED
MASTER + connected local=OPTIMIZED remote=TRANSITIONING

[X86][APX] Use EVEX BLSI/BLSMSK for i8 patterns with EGPR (#226796)
This is a follow-up to #204746 and #205093, which added the i8 BLSI and
BLSMSK patterns.
The i8 BLSI/BLSMSK patterns were defined outside of Bls_Pats and always
selected the VEX forms, so with EGPR the register allocator could not
assign r16-r31 to their operands. Move them into Bls_Pats so that the
_EVEX variants are selected when EGPR is available.

[InstCombine] Declare command line options in TableGen (#227948)
Follow-up to the framework #226087:
Move the cl::opts into InstCombineCLOptions.td, with `prefix =
"instcombine-"`: -instcombine-max-num-phis sets CLOpts.max_num_phis.
CLOpts also replaces InstCombiner::MaxArraySizeForCombine.
Options that were not cl::Hidden are now listed by -help-hidden only,
and -instcombine-lower-dbg-declare is now a bool.

[mlir][xegpu] Distribute extract_strided_slice over multiple dims (#227478)
SgToLaneVectorExtractStridedSlice only handled a single distributed
dimension, and this PR handles distributing multiple dimensions. It
scales each distributed dim by its own lane_layout entry. Both the size
and the offset along a dim shrink by the number of lanes that split it.
A dim the lanes do not split keeps its offset untouched, and may still
carry non-unit lane_data as before.

[IDF] Use BitVectors indexed by DFS number for visited sets (NFC). (#227832)
IDFCalculatorBase::calculate tracks visited dominator tree nodes in two
SmallPtrSets. The DFS numbers computed at the start of calculate are
unique and dense in [0, number of nodes), with the DFS out-number of the
root being the number of nodes, so use them to index BitVectors instead.
This reduces hashing overhead and improves compile-time, depending on
configuration/workload:
stage1-O3: -0.04%
stage1-ReleaseThinLTO: -0.05%
stage1-ReleaseLTO-g: -0.22%
stage1-aarch64-O3: -0.06%

[mlir][vector] Add an eliminate-vector-masks pass (#226517)
`eliminateVectorMasks` had no in-tree caller other than a test pass, so
no pipeline could use it. This exposes it as an opt-in
`-eliminate-vector-masks` pass and drops the test pass.
The pass rewrites `vector.create_mask` ops that can be proven all-true
into `vector.constant_mask`; canonicalization then folds those away, so
a masked transfer becomes an unmasked one. Mask sizes are bounded with
`ValueBoundsOpInterface`, so a loop-derived size like `%dim - %iv` can
be proven.
Scalable dimensions need a `vscale` range, given by
`vscale-min`/`vscale-max`. Leaving them unset means fixed-size reasoning
only; a half-specified or inverted range is rejected rather than
silently ignored.
`eliminate-masks.mlir` keeps its checks and only switches its two RUN
lines, which shows the pass behaves as the test pass did.

math/py-numpy-stl: update to 4.0.1
numpy-stl 4.0.1
Fixed
Resolved all mypy and basedpyright findings; malformed # type:
ignore[ty:...] suppressions replaced by typing.cast or restructured code.
Replaced argparse.FileType (deprecated since Python 3.14) in the CLI
with path arguments opened after parsing; stdin/stdout - semantics unchanged.
This also fixes a latent bug where the output file was truncated at
argument-parsing time, before the input was validated.
The optional speedups were silently disabled with speedups>=2.1.0,
which moved ascii_read/ascii_write to the speedups.stl submodule.
The import now targets that submodule and the fast extra requires
speedups>=2.1.0.
Changed
CI now enforces all four type checkers (pyrefly, mypy, basedpyright, ty).
[SPIRV] Fix crash when two functions share an alias scope (#225017)
When two functions referenced the same alias scope metadata, they were
incorrectly sharing a virtual register. This caused either a crash or
broken SPIR-V output with undefined references. The fix ensures each
function creates its own virtual register for alias scope metadata

[NFCI][llvm-profdata] Propagate Error in loadInput and mergeWriterContexts
Propagate Error from loadInput and mergeWriterContexts in mergeInstrProfile,
supplementInstrProfile, and overlapInstrProfile. In mergeInstrProfile's
ThreadPool, catch errors from worker threads, stop scheduling new jobs,
and return the first encountered fatal error.
Ensure ~WriterContext() consumes any pending unhandled errors in
WriterContext::Errors upon destruction.
Not NFC as destructors are run on the stack and ThreadPool workers exit
earlier on error.
