Reject recursive permissions changes on S3 bucket mountpoints
filesystem.chown, filesystem.setperm and filesystem.setacl now refuse
a recursive change whose path is the mountpoint of a dataset consumed
by an S3 bucket, or that would traverse into one from above. The error
points the caller at the bucket's s3data directory instead, since a
recursive change over the whole bucket may have undefined behavior and
expose security risks.
[LLVMABI] Handle Atomic types in the LLVM ABI library (#221367)
The LLVM ABI library's type system had no way to represent atomic types,
so Clang's QualTypeMapper was just mapping them directly to the
underlying value type. This resulted in mis-classification of some
function signatures involving atomic types.
This change adds AtomicType to the ABI type system and QualTypeMapper.
The actual classification didn't require any updates. Simply having the
atomic type as a distinct type was sufficient for it to produce the
expected results.

Respect target boundaries during OpenMP variant lowering
Stop collecting construct traits at the innermost TARGET so lowering
agrees with semantic analysis when selecting metadirective replacements
and DECLARE VARIANT callees.
[lldb][debugserver][NFC] Share the expedited-memory type and emitters (#222911)
Expedited memory had two representations:
- The frame pointer backchain used `StackMemory`, a fixed
`uint8_t[2 * sizeof(nub_addr_t)]` plus a length, held in a `std::map`
keyed
by frame address.
- Frame 0's window used `ExpeditedMemory`, which owns a
`std::vector<uint8_t>`.
Three call sites then open-coded the same emit loop, twice into a JSON
array
and once into a stop reply.
Keep `ExpeditedMemory` for both and emit through
`AppendExpeditedMemoryToJSON`
and `AppendExpeditedMemoryToStopReply`. `ReadFrameZeroStackMemory`'s
local
`read_range` lambda becomes `AppendExpeditedMemory`. `ReadStackMemory`

[libc] Implement pthread_attr_[gs]etscope (#222956)
This patch implements pthread_attr_getscope and pthread_attr_setscope.
Same as other libraries, we only support the system contention scope
(PTHREAD_SCOPE_SYSTEM). Process contention scope (PTHREAD_SCOPE_PROCESS)
is not supported, and would basically require a userspace N:M threading
implementation. Since this value cannot be checked in the kernel, I
reject it directly during the attribute set operation, and don't even
bother storing it in the attribute object.

[SCEV] Init BE vars to CouldNotCompute in howManyLT (NFC) (#222892)
This avoids the risk of initializing ExitLimit with nullptr BE
variables, and cast-asserts on nullptr. This makes the null-BE check
unnecessary, and it can be handled by the common code that follows.
[CIR][OpenCL] Lower OpenCL language version metadata to LLVM dialect

fix: Supply the HIP SPIR-V version only for metadata emission
Fix the assertion exposed by PR #214246 under the version invariant from PR #219687. Supply OpenCL 2.0 in classic CodeGen and CIRGen without changing HIP language options or enabling OpenCL-only Sema restrictions.

[CIR][OpenCL] Emit OpenCL language version metadata in CIR

[CIR][OpenCL] Add OpenCL language version module attributes

[lldb-dap] Report the compile unit of a stack frame (#222512)
Add StackFrame.compileUnitId, an id that names the frame's compile unit
within the module already reported as StackFrame.moduleId. Clients
resolve it through the compileUnits request, which now reports the same
id on each CompileUnit and takes an optional compileUnitIds filter to
ask for individual compile units instead of the module's full list.
CompileUnitsRequestHandler declared its arguments optional but
dereferenced them unconditionally, so a compileUnits request carrying no
arguments crashed the adapter. Drop the optional and let the request
framework reject the request instead.
LinuxKPI: Run irq_work callbacks under RCU protection
Linux executes irq_work callbacks from an interrupt context that
provides implicit RCU read-side protection. LinuxKPI dispatches these
callbacks through a taskqueue, so provide equivalent protection
explicitly.
This prevents an RCU grace period from completing while an irq_work
callback is still using an RCU-protected object.
