[MCA] Make `ResourceSizeMask` const (#189453)
This patch marks the already effectively constant `ResourceSizeMask` as
`const`. It adds a helper `computeResourceSizeMask()` to initialize it
in the member initializer list.
Add a target triple to clang/test/Modules/pr189415.cppm (#189937)
Not all targets support thread_local, so in some environments the test
would fail with:
tools/clang/test/Modules/Output/pr189415.cppm.tmp/counter.cppm:6:1:
error: thread-local storage is not supported for the current target

ip6_mroute: Fix the type name in sysctl_mfctable()
No functional change since apparently it's fine to compute the size of
a pointer type when the base type is undefined.

vmm: Restore the ability to create VMs as root in a jail
The new PRIV_VMM_CREATE and DESTROY permissions should be allowed by
jails, so need to be added to the list in prison_priv_check(). Then,
modify vmmdev_create() to verify that the jail was created with the
allow.vmm flag. This is already verified when opening /dev/vmmctl, but
checking again doesn't hurt and ensures that one can't pass the
allow.vmm policy by passing a vmmctl fd along a unix domain socket from
outside the jail.
Rename vmm_priv_check() to vmm_jail_priv_check() to make the function's
purpose more clear.

pmap: Do not use PMAP_LOCK_INIT with kernel_pmap
The kernel_pmap lock is a bit special: it does not need the DUPOK flag,
and it really belongs to a different lock class. If it belongs to the
same class as regular pmap locks, then witness may report warnings when
performing UMA allocations under a regular pmap lock, if the allocation
triggers a pmap_growkernel() call.
Replace instances of PMAP_LOCK_INIT(kernel_pmap) with inline mtx_init()
calls to silence some witness warnings for harmless behaviour I see with
some uncommitted test programs.

[RISCV] Remove codegen for VP float rounding intrinsics (#189896)
Part of the work to remove trivial VP intrinsics from the RISC-V
backend, see
https://discourse.llvm.org/t/rfc-remove-codegen-support-for-trivial-vp-intrinsics-in-the-risc-v-backend/87999
This splits off seven intrinsics from #179622.
We now generate vfcvt.rtz for llvm.vp.roundtozero. It looks like we
should have been using the codegen for llvm.trunc for it, but we somehow
missed that.

[AArch64][GlobalISel] Selet SQDMLSLv1i64_indexed when vector_extract present
Like SQDMLALv1i64_indexed, selecting this intrinsic reduces the number of instructions generated by 1, as it performs both the vector extract and the sqdmlal in one instruction.
This only works when the vector to extract from is v4i32, not v2i32. This is due to some issues GlobalISel has selecting intrinsics using v2i32.

## 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

[AArch64][GlobalISel] Add test for v4i32 vector extract sqdmlal/sqdmlsl
1. Tests only test v4i32 versions of the intrinsic, as v2i32 currently doesn't work.
2. GlobalISel currently generates poor code in the sqdmlsl case. To fix, the sqdmlalvi64_indexed pattern needs to be copied over for sqdmlsl.
[MLIR][Affine] Fix dead store elimination for vector stores with different types (#189248)
affine-scalrep's findUnusedStore incorrectly classified an
affine.vector_store as dead when a subsequent store wrote to the same
base index but with a smaller vector type. A vector<1xi64> store at
[0,0] does not fully overwrite a vector<5xi64> store at [0,0], so the
first store must be preserved.
The loadCSE function in the same file already had the correct
type-equality check for loads; this patch adds the analogous check for
stores in findUnusedStore.
Fixes #113687

[AArch64][GlobalISel] Select lane index sqdmlal when vector_extract of v4i32 present
SQDMLALv1i64_indexed takes in an index of a vector as its final operand, meaning it doesn't need to extract the element in a separate instruction.
This only works when the vector to extract from is a v4i32. Currently, extracting from a v2i32 doesn't work, and I'm unsure why.
[AArch64][llvm] Gate some `tlbip` insns with either +tlbid or +d128 (#178913)
Change the gating of `tlbip` instructions (`sysp` aliases) containing
`*E1IS*`, `*E1OS*`, `*E2IS*` or `*E2OS*` to be used with `+tlbid` or
`+d128`. This is because the 2025 Armv9.7-A MemSys specification says:
```
All TLBIP *E1IS*, TLBIP *E1OS*, TLBIP *E2IS* and TLBIP *E2OS*
instructions that are currently dependent on FEAT_D128 are updated
to be dependent on FEAT_D128 or FEAT_TLBID
```
See also change #178912 where the gating of `+d128` for `sysp` was
removed.

Target specific flags (Notably `-mimplict=always` for ARM) are not
