tracing: tell git to ignore the generated 'undefsyms_base.c' file
This odd file was added to automatically figure out tool-generated
symbols.
Honestly, it *should* have been just a real honest-to-goodness regular
file in git, instead of having strange code to generate it in the
Makefile, but that is not how that silly thing works. So now we need to
ignore it explicitly.

[clang][riscv] Add tests for __builtin_reduce_X support [NFC] (#193082)
It turns out we already support use of the __builtin_reduce_ family of
builtins on the builtin RVV types, but we have no test coverage which
demonstrates this.
Note that __builtin_reduce_mul is a bit of a cornercase as currently the
clang part works just fine, but the lowering will crash since we don't
have a vredprod-esq instruction. (See
https://github.com/llvm/llvm-project/pull/193094 for the lowering fix.)
[offload] Remove unnecessary extra allocations in kernel replay tool (#193108)
The tool had two extra allocations holding the device memory and
globals. Apparently, the AMDGPU plugin failed in the past to transfer
data from the file memory mapping, and required these extra buffers.
After testing it on MI300A and MI250X, this issue is not present
anymore. Thus, we are removing them for now.

"The main 'feature' is a workaround for C1-Pro erratum 4193714
requiring IPIs during TLB maintenance if a process is running in user
space with SME enabled.
The hardware acknowledges the DVMSync messages before completing
in-flight SME accesses, with security implications. The workaround
makes use of the mm_cpumask() to track the cores that need
interrupting (arm64 hasn't used this mask before).
The rest are fixes for MPAM, CCA and generated header that turned up
during the merging window or shortly before.

[SLP] Normalize copyable operand order to group loads for better vectorization
When building operands for entries with copyable elements, non-copyable
lanes may have inconsistent operand order (e.g., some lanes have
load,add while others have add,load for commutative ops). This prevents
VLOperands::reorder() from grouping consecutive loads on one side,
degrading downstream vectorization.
Normalize in two steps during buildOperands:
1) Majority voting: swap lanes that are the exact inverse of the
majority operand-type pattern.
2) Load preference: if the majority pattern has loads at OpIdx 1
(strict majority), swap to put loads at OpIdx 0, enabling
vector load + copyable patterns.

Merge tag 'sh-for-v7.1-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux
Pull sh updates from John Paul Adrian Glaubitz:
"Two patches from Thomas Zimmermann, one by Tim Bird and one by Thomas
Weißschuh.
The first patch by Thomas Zimmermann adds a missing include in dac.h
for SH-3 which became necessary after 243ce64b2b37 ("backlight: Do not
include <linux/fb.h> in header file") which made __raw_readb() and
__raw_writeb() inaccessible in dac.h.
Thomas' second patch drops CONFIG_FIRMWARE_EDID for SH as it depends
on X86 or EFI_GENERIC_STUB which are not defined on SH for obvious
reasons.
The patch by Tim Bird fixes just a small typo in two SPDX ID lines
which he stumbled over by accident.
And, least but not last, the patch by Thomas Weißschuh removes the

[CodeGen] Add MachineBlockHashInfoAnalysis for the new pass manager (#193107)
This patch introduces MachineBlockHashInfoAnalysis and its corresponding

This allows running -passes="print<machine-block-hash>" via llc.
Can't merge before #192826, and don't want to mix test patch with
determinism fix in #192826.
This is #192911 which was accidentally merged into spr/users branch.

[SLP] Improve cost model for i1 select-as-or/and patterns
Model `select i1 %c, i1 true, i1 %d` as `or` and
`select i1 %c, i1 %d, i1 false` as `and` in the SLP cost model, since
these are the operations the backend will lower them to. The previous
select cost overestimated the vector cost of these patterns, preventing
profitable vectorization of i1 condition chains.
