[sanitizer_common] Implement address sanitizer on AIX: platform specific support (#131866)
Add recognition of AIX and some platform specific changes. This lays the
groundwork to implement AIX in sanitizer_common/asan.

[LifetimeSafety] Warn on implicit this lifetimebound violations (#196926)
With this change we report `[[clang::lifetimebound]]` violations on the
implicit `this` parameter.
It also adds a helper to retrieve the `[[clang::lifetimebound]]`
attribute on method declarations, so diagnostics can point directly at
the attribute location.
[CIR] Global-TLS variable 'call' rewriting- (#197026)
This is a followup to my previous patch to handle global/namespace
thread local variables. This patch handles the
re-writing/lowering-prepare of the `get-global` for these variables.
Each call to one of these is required to go to a 'wrapper' function,
which optionally calls the initializer. This patch does not handle the
initializer call (so each wrapper call is a very simple 'return the
variable'), as that will be handled in a followup.
Also, variables without initialization don't use a wrapper in Classic
Codegen, however this patch does. The followup patch that will call the
initializer will skip the call to the initializer, but leave the wrapper
in place. This is a necessity due to how we handle global ops/get-global
ops: we won't know whether there is a required ctor/dtor that needs an
initializer at the time of wrapper-write-replacement.
Fix "author" handling in GitHub PR Greeter (#197140)
This is a follow-up to #194307 and fixes the issue reported in:
* https://github.com/llvm/llvm-project/pull/194307#issuecomment-4426270256
Use the same author-detection logic in `PRGreeter` as in
`PRBuildbotInformation`, so both components handle PR authors
consistently.
[libclc] Consolidate `amdgpu` and `amdgcn` architectures consistently (#197233)
Summary:
Currently we did not pass all checks with amdgpu triple as we did with
amdgcn. SPIR-V set this pattern so let's make it consistent.
Merge tag 'probes-fixes-v7.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull probes fixes from Masami Hiramatsu:
- kprobes: skip non-symbol addresses in kprobe_add_ksym_blacklist()
Since the ftrace adds its NOPs at .kprobes.text section (which stores
an array), a wrong entry is added when loading a module which uses
"__kprobes" attribute.
To solve this, add "notrace" to __kprobes functions
- test_kprobes: clear kprobes between test runs
Clear all kprobes in the test program after running a test set,
because Kunit test can run several times
- fprobe: Fix unregister_fprobe() to wait for RCU grace period

[llvm][tools] Use temp dir for offload-binary unbundling test (#197234)
Certain environments will leave some of the test dirs read-only for
immutability purposes. Create a new temporary directory so that
llvm-offload-binary has a writable directory to unbundle the image into.
With this method we can also delete the temporary directory preventing
breakage of the failure from still passing tests due to leftover files.
Delete top level mops-instructions.s file (#197244)

Hyper-V: hn: just call vf's ioctl when changing mtu
When changing mtu, if a vf is attached to the netvsc interface, just
calling its ioctl to change vf's mtu is good enough.

arm64: VM/PMAP changes for CCA guest support
When in a realm:
- Mappings with mode VM_MEMATTR_DEVICE and VM_MEMATTR_DEVICE_NP are
unprotected
- Imported busdma buffers in protected memory are always bounced
- If EARLY_PRINTK is in use, the UART physical address must be in the
unprotected address space

arm64: Load SOCDEV_PA as a literal rather than an immediate
When EARLY_PRINTK is used in a realm environment, the UART physical
address must be in the unprotected address space. The resulting
physical address will not generally fit in an immediate, so use a
literal instead.

physmem: Add a way to read all memory
In Arm CCA we need to find all memory to protect it. This needs to find
all memory, ignoring any excluded memory to protect it from the host.
Add physmem_all that reads all physical memory regions.

[AMDGPU][MIRFormatter] Human-readable mask for S_WAITCNT_soft (#197075)
This patch reuses the S_WAITCNT mask printer and parser for
S_WAITCNT_soft. It prints the mask in a human-readable format, showing
the counter values like `Vmcnt_<NUM>_Expcnt_<NUM>_Lgkmcnt_<NUM>`.
[clang-tidy] Add `llvm-formatv-string` (#195974)
Adds a clang-tidy check to perform some validation on `llvm::formatv`
calls. Similar to the built in support Clang has for checking printf
calls.
The validations are:
- The number of unique format indices matches the number of arguments.
- Every argument is used by the format string.
- Automatic and explicit indices are not mixed.
This includes a config option (`AdditionalFunctions`) to perform the
same validation checks on other functions which take formatv inputs.

[AsmParser] Use cantFail for FloatLiteral string conversion (#197064)
With assertions disabled but `LLVM_ABI_BREAKING_CHECKS=FORCE_ON`, the
`assert` was elided, the Expected stayed unchecked, and the subsequent
`*Except` tripped `fatalUncheckedError`. Fix this by switching to
`cantFail`.
