[OFFLOAD] Add olIterateCompatibleDevices API (#226441)
Add a new API that iterates through all devices. For devices compatible
with the image (and their platform too) it calls the Callback.

[Clang][Sema] Create LocalScope for Variable Template (#228280)
A variable template should create its own LocalScope, as it should be
opaque to other instantiations. This can occur when there are multiple
instantiations in the same lexical scope. The correct behavior is that
these instantiations should not be chained together.

[Clang] Properly parse enumeration declarations with fixed underlying type in generic associations (#210353)
added a new `ParsingGenericAssociationType` flag that is managed by
`GenericAssociationTypeRAIIObject`. If that flag is true, when
encountering a `:` after enum name, try to parse next token as a type,
if successful, then that's the underlying type, if failed, then that is
the end of the enum declaration, and the colon will be parsed as the
generic association.
to check if the next tokens are a type, I added a new function
`isNextCXXTypeId`, which works the same as `isCXXTypeId`, but starts the
check one token ahead.
Fixed #207357

llvm-exegesis: Set the module triple and ABI-aware DataLayout
The module used to assemble snippets only had a DataLayout set, which
was computed without the target ABI. Set the target triple on the
module, synthesize the "target-abi" module flag from the
TargetMachine's ABI option, and compute the DataLayout from it.
Without the ABI, a TargetMachine with a non-default ABI would hit the
incompatible DataLayout error when creating the MachineFunction.

sched_ule: fix invalid tdq_slice() and sched_slice_min
sched_slice_min should always to be greater than zero. When modifying
sched_slice through sysctl, if the new value is less than
SCHED_SLICE_MIN_DIVISOR, sched_slice_min is computed to zero. Add
imax(1, ...) to prevent this.
tdq_slice() should not return a value less than sched_slice_min since
that will cause integer underflow of ts2->ts_slice in
sched_ule_fork_thread. SCHED_SLICE_MIN_DIVISOR is currently set to 6 so
when load is 5 and sched_slice is 4, the two if conditions in
tdq_slice() will pass and the function will return zero. Thus use imax()
so tdq_slice returns sched_slice_min at minimum.

sched_4bsd: fix vague comment
The comment "was incremented in schedcpu()" doesn't give enough
background for decrementing ts_slptime by 1 (thus ignoring decay_cpu()
for 1 ts_slptime). More accurately, ts_slptime is decremented by 1
because decay_cpu() has already executed once in schedcpu() when
ts_slptime was 1.

[TableGen] Generate library option structs with llvm-min-tblgen (#228338)
-gen-opt-parser-defs lives in llvm-tblgen, so a library whose options
are declared in TableGen (CGData, InstCombine, MC) waits for llvm-tblgen
to build before any of its sources compile, while it otherwise needs
only llvm-min-tblgen.
Move OptionParserEmitter and OptEmitter into TableGen/Basic, which
llvm-min-tblgen consists of, and generate those structs with
llvm-min-tblgen.

too. code-server now runs on Node.js 24 instead of Node.js 22.

NAS-143382 / 25.10.8 / Fix rsync extra arguments quoting (by themylogin) (#19917)
https://github.com/truenas/middleware/pull/19496 introduced a
regression: the user had `--rsync-path="sudo rsync"` in their `extra`
args, and the argument value was used literally, causing `bash: line 1:
sudo rsync: command not found` error (it tried to launch `sudo rsync`
binary which didn't exist).
This is a 25.10.7 bug that didn't exist in 25.10.6, so, if we're ever
publishing 25.10.8, it should be backported there.

sched_4bsd: remove obsolete comment
In old Unix, the whole process address space including scheduler-related
data was paged out to disk. We now allocate thread-related data with UMA
on wired memory which never page out. Thus this comment is now obsolete.

two CPU-bound threads with different nice values can have the same

Add static assertion on NICE_WEIGHT to ensure that there is always
enough room for nice values in the both end of the timeshare priority

[llvm-objcopy] Handle SHF_ALLOC relocation sections in relocatable files (#227204)
llvm-objcopy treats every SHF_ALLOC relocation section as dynamic and
requires its sh_link to refer to .dynsym. Linux livepatch modules
(ET_REL) contain SHF_ALLOC .klp.rela.* sections linked to .symtab
(SHF_ALLOC keeps them in module memory until the patched module loads),
so llvm-objcopy rejects them:
```
error: Link field value 4 in section .klp.rela.vmlinux.text is not a symbol table
```
A relocatable file has no dynamic symbol table, so treat all of its
relocation sections as static, as BFD does. Their symbol indexes are
then updated when the symbol table changes. Since SHF_ALLOC no longer
distinguishes RelocationSection from DynamicRelocationSection, record
the kind in RelocationSectionBase.

[mlir][MathToLLVM] Fix math.fpowi incorrectly being mapped to llvm.powi (#226089)
`math.fpowi` allows vector exponents, while `llvm.intr.powi` only takes
scalar exponents. This led to vector `math.fpowi` ops being lowered to
invalid IR.
This PR adds support for constant splat exponents, and leaves other
vector cases unconverted.
