[lldb][Platform] Handle LoadScriptFromSymFile per-module FileSpec (#189696)
This patch changes the `Platform::LocateXXX` to return a map from
`FileSpec` to `LoadScriptFromSymFile` enum.
This is needed for https://github.com/llvm/llvm-project/pull/188722,
where I intend to set `LoadScriptFromSymFile` per-module.
By default the `Platform::LocateXXX` set the value to whatever the
target's current `target.load-script-from-symbol-file` is set to. In
https://github.com/llvm/llvm-project/pull/188722 we'll allow overriding
this per-target setting on a per-module basis.
Drive-by:
* Added logging when we fail to load a script.
[TargetLowering] Replace always true if with an assert. NFC (#189750)
We already returned for UADDSAT/USUBSAT leaving SADDSAT/SSUBSAT as the
only opcodes that can get here.
dbufstat: add man page
Add a manual page for the dbufstat(1) utility which displays
statistics about the DMU buffer cache. Document all options,
fields, and include sample output from a live FreeBSD system.
Also add dbufstat.1 to Makefile.am and Debian packaging.

[compiler-rt][asan] Forward fix for free_aligned_sized_mismatch.cpp (#189760)

seem to support aligned_alloc.
NAS-140428 / 27.0.0-BETA.1 / Fix apps container UI shell (#18606)
## Problem
Opening a shell for a Docker app container (`app_name` + `container_id`)
failed because the `container_id` block ran unconditionally before the
`app_name` check — passing a Docker container name (string) to
`container.nsenter`, which expects an integer incus/libvirt container
ID.
## Solution
Made the `container_id`/`nsenter` path an `elif` under the `app_name`
check,
so it only runs for standalone incus/libvirt containers.
[RISCV][P-ext] Rename simm8_unsigned/simm10_unsigned used PLUI/PLI. NFC (#188808)
Replace unsigned with plui or pli_b to better indicate their usage.
Templatize the render function and rename it addSExtImm instead of
addSImm*Unsigned.
[mlir][MemRef] Migrate memref dialect alias op folding to interface (#187168)
This PR adds code to FoldMemRefAliasOps / --fold-memref-alias-ops to use
the new IndexedMemoryAccessOpInterface and
IndexedMemCopyOpInterface and implement those operations for relevant
operations in the memref dialect.
This is a reordering of the changes planned in #177014 and #177016 to
make them more testable.
There are no behavior changes expected for how memref.load and
memref.store behave within the alias ops folding pass, though support
for new operations, like memref.prefetch, has been added.
Some error messages have been updated because certain laws of
memref.load/memref.store have been moved to IndexedAccessOpInterface.

sysutils/sylve: update to v0.2.3
Pet port while here:
- include bsd.port.options.mk to support ARCH, as make -V PORTVERSION
will fail without this.
- switch to USES=samba:run so that alternate samba versions can be
selected if required.

Pull sched_ext fixes from Tejun Heo:
- Fix SCX_KICK_WAIT deadlock where multiple CPUs waiting for each other
in hardirq context form a cycle. Move the wait to a balance callback
which can drop the rq lock and process IPIs.
- Fix inconsistent NUMA node lookup in scx_select_cpu_dfl() where
the waker_node used cpu_to_node() while prev_cpu used
scx_cpu_node_if_enabled(), leading to undefined behavior when
per-node idle tracking is disabled.

Bridge speculative and prescient prefetchers
There are cases when we need to read large objects sequentially.
Prescient prefetcher may be limited by size, trying to prefetch
it all at once. Speculative prefetcher can do it nicer for ARC,
but needs a ramp-up period at the beginning.
To cover this gap, introduce dmu_prefetch_stream(), priming the
speculative prefetcher to either go full speed on first demand
request, or even start some prefetch immediately, but continue
following the demand later.

[LLDB] Add allow_var_updates to DIL and CanUpdateVar to SetValueFromInteger (#186421)
In preparation for updating DIL to handle assignments, this adds a
member variable to the DIL Interpreter indicating whether or not
updating program variables is allowed. For invocations from the LLDB
command prompt (through "frame variable") we want to allow it, but from
other places we might not. Therefore we also add new StackFrame
ExpressionPathOption, eExpressionPathOptionsAllowVarUpdates, which we
add to calls from CommandObjectFrame, and which is checked in
GetValueForVariableExpressionPath. Finally, we also add a parameter,
can_update_vars, with a default value of true, to
ValueObject::SetValueFromInteger, as that will be the main function used
to by assignment in DIL.

Pull cgroup fixes from Tejun Heo:
- Fix cgroup rmdir racing with dying tasks.
Deferred task cgroup unlink introduced a window where cgroup.procs
is empty but the cgroup is still populated, causing rmdir to fail
with -EBUSY and selftest failures.
Make rmdir wait for dying tasks to fully leave and fix selftests to
not depend on synchronous populated updates.
- Fix cpuset v1 task migration failure from empty cpusets under strict
security policies.
When CPU hotplug removes the last CPU from a v1 cpuset, tasks must be
migrated to an ancestor without a security_task_setscheduler() check
that would block the migration.
