[llvm][RISCV] Revise xsfmm intrinsic interface. (#201527)
This patch does 2 things:
1. Change matmul interface to use newly defined OFP8 RVV types.
2. change all of matmul overloaded interfaces to only keep only widen
information and eliminate types information.
[clang][RISCV] Handle VLS CC on unsupported primitive type in aggregate type (#203898)
We handled this for pure vector type before but missed the aggregate
types, this patch try to apply same mechanism on them where unsupported
vector types are converted to same size i8 vector types.
[lld-macho] Relax safe ICF's keepUnique for ld64-coalesced data sections (#193125)
#188400 regressed data-section folding under --icf=safe{,_thunks}:
no-addrsig fallback, and over-broad compiler-emitted addrsig entries
covering data symbols, both caused markSymAsAddrSig to set keepUnique on
data sections, after which foldIdenticalSections refused to fold them.
ld64 coalesces __cfstring, __objc_classrefs and __objc_selrefs
unconditionally regardless of addrsig, so ignore keepUnique for them as
a workaround for the imprecise addrsig payload.
[orc-rt]R Align scope-exit with LLVM (rename to scope_exit, use CTAD) (#205020)
This renames the orc_rt::detail::ScopeExitRunner class to
orc_rt::scope_exit and adds a class template argument deduction guide.
Hyper-V passes bootstrap entropy to guests via the ACPI OEM0 table. Use it.
We verify that the OEM0 table has the correct Microsoft IDs, skip the header,
feed the remaining contents to the kernel entropy pool, and wipe them in-place
to prevent later extraction via /dev/acpi (e.g. with acpidump). This interface
doesn't seem to be documented but we handle it the same way Microsoft's own
Linux driver does.

firewire: NULL check on malloc in fw_busreset()
fw_busreset() allocates newrom with M_NOWAIT from interrupt context.
If the allocation fails, crom_load() dereferences a NULL pointer.
Skip the config ROM comparison on allocation failure so the next bus
reset will retry.

raise the size of amd64 kernel virtual address space from 4G to 512G
This allows mapping all of VRAM on recent Radeon cards where the
PCI BAR size is the full (> 4G) size.
Reported by Petre Rodan, who has a Radeon RX 6800 with 16G of VRAM.

[AtomicExpand] Add bitcasts when expanding store atomic vector (#197862)
AtomicExpand fails for aligned `store atomic <n x T>` because it
does not find a compatible library call. This change adds appropriate
ptrtoint + bitcast so that the call can be lowered, mirroring the
load-side handling.
Store-side counterpart to #148900. Stacked on top of
https://github.com/llvm/llvm-project/pull/201566.
