[mlir][reducer] Change mlir-reducer apply pattern logic (#195997)
This PR aligns the pattern application logic with the operation deletion
strategy, It indirectly achieves the separation of operation deletion
and pattern application. It also fixes a bug where trivially dead ops
within `opsInRange` was being incorrectly deleted when apply patterns.
While `opsNotInRange` grows from zero (via binary search), `opsInRange
`shrinks from the entire module down to zero. This fixes a crash where
patterns were initially applied to the whole module. If the module in
the current iteration is 'uninteresting', it gets erased. Consequently,
when the iterator increments, it fails to clone the parent iteration's
module, leading to a crash.

[MLIR][XeGPU] Fix layout inference issues blocking MXFP_GEMM test (#196243)
This branch fixes layout inference issues in XeGPU passes that were
blocking MXFP (microscaled floating point) GEMM workloads:
- Fix bitcast layout adjustment to use result shape instead of source
shape. The setupBitCastResultLayout function were incorrectly bounding
the layout adjustment loop against the source shape. Added tests.
- Fix blocking pass to drop inst_data from anchor operations. Operations
whose shape already matches inst_data don't get unrolled, so their
layout attributes retained stale inst_data that broke downstream passes.
Now inst_data is unconditionally stripped from all op attributes after
blocking.
- Propagate layout to both results of vector.deinterleave. The layout
recovery pass was only setting the layout on result 0, leaving result 1
without a layout.

Merge tag 'selinux-pr-20260507' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux fixes from Paul Moore:
- Allow for multiple opens of /sys/fs/selinux/policy
Prevent a single process from blocking others from reading the
SELinux policy loaded in the kernel. This does have the side effect
of potentially allowing userspace to trigger additional kernel memory
allocations as part of the open/read operation, but this is mitigated
by requiring the SELinux security/read_policy permission.
- Reduce the critical sections where the SELinux policy mutex is held
This includes the patch to the policy loader code where we move the
permission checks and an allocation outside the mutex as well as the
the patch to checkreqprot which drops the code/lock entirely.
While the checkreqprot code had effectively been dropped in an

[NFC][AMDGPU] Use a worklist and remember results in AMDGPUAttributor
This was a recursive function with a Map to cache things that was never filled.
Now it's a worklist and the map is actually used.

[CodeGen][RISCV] Inline stack probes immediately after `allocateStack` in `eliminateCallFramePseudoInstr` (#195456)
This PR adds a call to `inlineStackProbe` immediately after
`allocateStack` in `eliminateCallFramePseudoInstr`. This allows code
generation for stack probe pseudoinstructions in non-entry BBs.
Fixes #195454.
[SLP]Bail out on non-schedulable expanded binop with stale operand deps
In tryScheduleBundle's DoesNotRequireScheduling path, an expanded binop
(shl X, 1 modeled as add X, X) doubles the dependency count of the
duplicated operand. If the operand has a
single IR use yet its ScheduleData already has Dependencies populated
by an earlier calculation that did not see the expanded duplicate use,
double decrement still exceeds calculateDependencies' single increment
and UnscheduledDeps goes negative.
Fixes #196281.
