[AArch64] Support TLS variables in debug info (#146572)
This adds an implementation of getDebugThreadLocalSymbol for AArch64 by
using AArch::S_DTPREL.
Fixes #83466
[LLD][AArch64] Handle R_AARCH64_TLS_DTPREL64 in non-alloc sections (#183962)
Clang plan to emit R_AARCH64_TLS_DTPREL64 in .debug_info (see PR
#146572). LLD currently fails to recognize this relocation.
This prevent the debugger from correctly locating TLS variables when
using the DWARF DW_OP_GNU_push_tls_address or DW_AT_location with DTPREL
offsets.
This patch adds support for R_AARCH64_TLS_DTPREL64, adds its mapping to
R_DTPREL.

vmgenc.4: Add VM Generation ID Counter manual
Document the vmgenc(4) ACPI driver which detects virtual machine
cloning and snapshot restoration via the VM Generation ID
specification. The driver reseeds the kernel entropy pool when
a generation change is detected.

[X86][APX] Remove NF entries in X86CompressEVEXTable (#189308)
NF (No-Flags) instructions should not compress to non-NF instructions,
as this would incorrectly modify flags behavior. The compression table
is only intended for encoding optimizations that preserve semantics.
This removes the incorrect NF entries that could have led to
miscompilation if the compression logic were applied.
nfs_nfsdserv.c: Fix handling of archive flag for mkdir
An NFSv4.1/4.2 client can set/clear the archive, hidden
and system flags when creating non-regular files, such
as directories.
Without this patch, the setting of va_flags causes an
EPERM failure, since they are specified for VOP_MKDIR(),
VOP_MKNOD() and VOP_SYMLINK().
This patch sets va_flags == VNOVAL for the above VOP_xxx()
calls and then sets/clears the flags after creation,
which fixes the problem.
This bug only affects the Windows NFSv4.1/4.2 client.

[CodeGenPrepare][NFC] Reland: Update the dominator tree instead of rebuilding it (#179040)
The original differential revision is https://reviews.llvm.org/D153638
Reverted in
https://github.com/llvm/llvm-project/commit/f5b5a30858f32e237636acd296b6d0f87c1dfe97
because of causing a clang crash.
This patch relands it with the crash fixed. Call `DTU->flush()` in each
iteration of `while (MadeChange)`
loop, flush all awaiting BasicBlocks deletion, and prevent iterator
invalidation.
[RISCV] Check hasVInstructions() rather than hasStdExtZbb() for UMAX/UMIN/SMAX/SMIN combines. (#189506)
The combines are related to combining min/max with vector reductions. I
don't think it matters if Zbb is enabled.
I did not merge this with other hasVInstructions() because I have a P
extension patch coming after this that will need to separate them.
[lldb] Fix copy-paste error in SetPrivateRunLockToRunning (#189322)
SetPrivateRunLockToRunning incorrectly delegated to
SetPrivateRunLockToStopped instead of SetPrivateRunLockToRunning,
causing the private run lock to never transition to the running state on
process resume.

zfs-set.8: document the received column and -o all option
The received column was missing from the list of columns displayed
by zfs get. Document it and note that it is not shown by default.
Also document the "all" keyword for the -o option, which selects
all five columns, and list the supported field names.

[CodeGen] Add additional params to `TargetLoweringBase::getTruncStoreAction` (#187422)
The truncating store analogue of #181104.
Adds `Alignment` and `AddrSpace` parameters to
`TargetLoweringBase::getTruncStoreAction` and dependents, and introduces
a `getCustomTruncStoreAction` hook for targets to customize legalization
behavior using this new information.
This change is fully backwards compatible from the target's point of
view, with `setTruncStoreAction` having identical functionality. The
change is purely additive.
Linux 7.0: ensure LSMs get to process mount options
Normally, kernel gives any LSM registering a `sb_eat_lsm_opts` hook a
first look at mount options coming in from a userspace mount request.
The LSM may process and/or remove any options. Whatever is left is
passed to the filesystem.
This is how the dataset properties `context`, `fscontext`, `defcontext`
and `rootcontext` are used to configure ZFS mounts for SELinux. libzfs
will fetch those properties from the dataset, then add them to the mount
options.
In 0f608aa6ca (#18216) we added our own mount shims to cover the loss of
the kernel-provided ones. It turns out that if a filesystem provides a
`.parse_monolithic callback`, it is expected to do _all_ mount option
parameter processing - the kernel will not get involved at all. Because
of that, LSMs are never given a chance to process mount options. The
`context` properties are never seen by SELinux, nor are any other
options targetting other LSMs.
