[ELF] .note.gnu.property: Require padding for the last piece (#240238)
parseGnuPropertyNote skips pr_datasz rounded up to the alignment but
checks only pr_datasz, reading out of bounds when the padding is
missing. GNU ld reports such a note as corrupt.

[lldb] Skip TestScriptedFrameProvider expression test on non-x86 Linux (#240233)
`test_expression_at_frame_without_variables` still fails on aarch64
Linux after 58b0fd59e5fb with "Couldn't allocate space for materialized
struct".
The IR interpreter evaluates `1 + 1`, so no code runs in the inferior,
but LLDB still needs to allocate memory there for the expression's
arguments and result. On macOS, debugserver does that itself when it
gets the `_M` packet, using `mach_vm_allocate()`. On x86 Linux,
lldb-server does it by running the `mmap` syscall on the thread's real
registers. Neither path goes through LLDB's frames, so the scripted
frame 0 never matters there.
lldb-server doesn't implement `_M` on other Linux architectures, so on
aarch64 LLDB falls back to calling `mmap` in the inferior. Before making
that call, `Thread::CheckpointThreadState()` saves the registers of
frame 0, which is the scripted frame. Its `RegisterContextMemory` has no
backing address, so `ReadAllRegisterValues()` fails and the call is

devel/got: Cherry-pick patches for shared locking
When operating on a worktree, got locks the tree in order to avoid
problems with concurrent operations. Until now, got always used
exclusive locks, which caused problems when e.g. two separate parts
of the FreeBSD release build ran 'got tree' at once.
This has been fixed upstream but the 15.2 release cycle needs the
changes urgently and can't wait for the next got-portable release,
so cherry-pick those patches.

[SLP][NFC] Add tests for dependent seeds in rejected windows (#240208)
Precommit tests for the once-used seeds that depend on each other, such
as x * x and x * (x * x), whose window is rejected and whose users are
bypassed by the window walk.

[libc] Make a stream unbuffered when setvbuf is given a size of zero (#236517)
`setvbuf(f, nullptr, _IOFBF, 0)` and `setlinebuf(f)`, which is
`setvbuf(f, nullptr, _IOLBF, 0)`, take the branch that stores the
caller's buffer. That buffer is null, but the requested mode is kept, so
the stream is left fully or line buffered with no buffer. A buffer of no
size holds nothing, so this sets the mode to `_IONBF` to match.
Where it came from: with my libc `setlinebuf(stdout)` followed by
another write crashed `bluetoothctl --help` when stdout was a pipe,
through a null buffer in a line buffered stream. I could not reproduce
that crash in a unit test on current main, so the tests added here pass
with and without the change. They pin the behaviour a program can see: a
zero sized stream shows its writes without a flush, and a sized one
still waits for `fflush`. Nothing public reports the buffering mode, so
I can't test the mode directly.
AI disclosure: this patch was written with Claude Code. I reviewed the
change and ran the new tests.
