[mlir][arith] Fix crash in IntRangeOptimizations due to stale solver state (#186187)
When the IntRangeOptimizationsPass runs applyPatternsGreedily with
constant folding enabled, constant folding can restructure blocks — for
example by removing a block argument. The integer range solver, which
pre-computed range information for the original block arguments, is now
out of sync: subsequent range queries about the new (reused) argument
positions return stale information computed for the old arguments,
causing crashes.
Fix by passing enableConstantFolding(false) in GreedyRewriteConfig so
that the solver's state remains consistent with the IR throughout the
rewrite.
Fixes #122076

Fix TNC sync_interface_ips empty IPs and repeated concurrent calls
This commit fixes an issue where sync_interface_ips could send empty IPs to the
TNC account-service (causing 400 errors) and where concurrent netlink events
would each independently hit the TNC API with the same payload.
When the HTTP call failed due to empty IPs, the cache was never populated, so
every subsequent netlink event retried the same failing call — creating an
infinite retry storm. Additionally, a single DHCP renewal would fire 3-5 netlink
events, each scheduling a call_later(5), all passing the cache check
simultaneously, and all hitting the TNC API concurrently with identical payloads.
An asyncio.Lock serializes concurrent sync_interface_ips calls so only the first
performs the HTTP sync while subsequent calls hit the cache and return early. An
empty IP guard skips the HTTP call when no IPs are available (static + dynamic
combined) but still caches the result to prevent retry storms.

[mlir][affine] Fix crash in AffineParallelLowering for unsupported reductions (#186189)
When lowering affine.parallel with a reduction kind that has no identity
value (e.g. "assign"), getIdentityValueAttr() returns nullptr. The
caller getIdentityValue() then passed this null TypedAttr to
arith::ConstantOp::create(), triggering an LLVM_ERROR crash:
"Failed to infer result type(s): arith.constant"

[mlir][arith] Fix crash when constant-folding truncf of inf to FiniteOnly float type (#186191)
When arith.truncf constant-folding converts a value such as infinity to
a type with fltNonfiniteBehavior::FiniteOnly (e.g. f4E2M1FN),
APFloat::convert hits an llvm_unreachable("semantics don't support
inf\!").
The fix adds early-exit guards in convertFloatValue() to return
failure() before calling APFloat::convert() when the source value is
infinity or NaN and the target type cannot represent it. This makes the
fold a no-op for unrepresentable special values, matching the existing
behavior for lossy ordinary conversions.
Fixes #185351

[mlir][python] Avoid needless std::string copies in properties. NFC. (#186190)
MlirStringRef is copied into a Python str by nanobind's type_caster

HBSD: Make sure the kinfo_file struct always gets zeroed
Similar to FreeBSD commit 25cc459286a02b646751541ccde5a33319471c73,
apply a memset in one of the core functions used to fill the structure.
This ensures that all kinfo_file structure allocations are zeroed (at
least, at the point of calling shm_fill_kinfo_locked).

[LLVM] Fix assertion when dropping type tests with SelectInst users (#185523)
The `dropTypeTests` function assumes that after removing `llvm.assume`
users of `llvm.type.test` calls, any remaining users must be PHINodes
(from merged assumes). However, SimplifyCFG can also merge two
`assume(type.test(...))` sequences into `assume(select(cond,
type.test_1, type.test_2))`, leaving SelectInst users that trigger the
assertion.
Extend the assertion to also accept SelectInst. The
`replaceAllUsesWith(true)` call already handles all user types
correctly — only the assertion was too narrow.
Respect cert checkbox when creating a user. Fixes #16721
Also fixes a case where the form was not displaying properly when there were input errors. This likely needs more testing to confirm each action case is being handled properly with and without input errors in the submission.
[clang-tidy][NFC] Move std system headers to separate dir in tests (#185533)

sound: enforce MASTER volume mute during playback
MASTER mute (vol.mute) works while audio is playing. However, if a
stream is stopped and restarted (PCMTRIG_STOP -> PCMTRIG_START), the
audio will resume even though the mixer shows the MASTER volume as
muted. Other streams that are already playing remain silent. New streams
may also start playing audio regardless of the MASTER mute state.
The volume feeder now considers the MASTER mute when determining whether
a channel should be muted. This ensures MASTER mute is consistently
enforced for all streams and removes the dependency on trigger-driven
state propagation.
Tested with Creative Labs CA0132 card.
