[LV] Add tests for wide induction wrap flags (NFC). (#226715)
Add tests for:
* inductions where the lane offsets may signed-overflow, even if the
scalar induction values do not,
* inductions whose increment does not directly update the phi, where the
increment's wrap flags do not apply to the induction,
* narrow inductions where the VF may exceed the signed maximum of the
induction type.

Pull PCI fixes from Bjorn Helgaas:
- Make BAR resize work even for devices where no upstream bridge is
visible to the OS, which fixes an amdgpu regression on SolidRun
HoneyComb, which doesn't expose Root Ports to the OS (Liz Fong-Jones)
- Omit bus properties in dynamic OF nodes when a bridge has no
subordinate bus, which fixes early boot hangs caused by NULL pointer
dereferences with CONFIG_PCI_DYNAMIC_OF_NODES enabled (Angel J)
- Disable enhanced atomics on AMD NBIO 7.7 and 7.11 to avoid silent
data corruption on 64-bit DMAs (Mario Limonciello)

[WebKit Checkers] Add built-in recognition for standard view types (#226350)
libc++ doesn't fully annotate `[[clang::lifetimebound]]` for all view
types. This results in false negatives in borrow checking.
Ultimately we need to fix this in libc++, but for now we can work around
the most common / most important false negatives. For example, borrow
checking can now check
for (auto& x : vector | std::views::reverse) { ... }

[libc++] Add static_assert diagnostics for LWG3133 named requirements (#212360)
Add a static_assert to both std::complex<T> and std::valarray<T>
requiring that T be a cv-unqualified object type that satisfies the
Cpp17DefaultConstructible, Cpp17CopyConstructible, Cpp17CopyAssignable,
and Cpp17Destructible named requirements, per the revised wording in
[numeric.requirements]. This mirrors the existing pattern already used
by std::optional<T>.
Non-_v (class-style) trait forms are used throughout so that the
assertion is well-formed even when <complex>/<valarray> are included in
C++03/11/14 mode.
Test coverage:
- A .verify.cpp for complex<T> and one for valarray<T>, each covering
six failure modes: cv-qualified types, and one type violating each of
the four named requirements individually.

[VPlan] Mark default value or ExtractLastActive as only first lane used. (#226153)
The default value (operand 0) of ExtractLastActive is the scalar value
of @llvm.experimental.vector.extract.last.active. Only the first lane is
used, mark accordingly.

[lld][LoongArch] Prevent relaxation oscillation for PCHi20 and CALL
Relaxation of pcalau12i+addi (relaxPCHi20Lo12, isInt<22>) and
call36/call30 (relaxMediumCall, isInt<28>) can oscillate: shrinking
one section moves a symbol, which flips isInt<N> for other sites and
changes bytesDropped again. In large programs (e.g. Rust) the PC of
a site can stabilize while Dest jitter near the range limit, so
remove keeps alternating between 0 and 4 and relaxOnce never settles.
Follow the same approach as RISCV::relaxCall: after a few passes, do
not allow remove to increase beyond the previous pass's value
(cur - delta). Pass that cap as prevRemove into the two helpers;
range checks may still clear remove (0) when the target goes out of
range.
No reduced in-tree stress test: the failure is layout- and
input-order-sensitive and was validated against a fixed response-file
reproduction in the bug issue.
arm64 pmap: Eliminate redundant icache synchronization
Creating an executable user-space mapping to write-back memory
synchronizes the icache with the page's contents, whether or not those
contents have changed since the previous synchronization. Use the pmap
private page flag PGA_ICACHE_SYNCED to record that the icache has been
synchronized with a managed page's contents and that the page has no
writable mappings. When the flag is set, the creation of another
executable mapping to the page can skip the synchronization. The flag
is cleared when a writable mapping to the page is created, using a
single atomic operation that keeps PGA_WRITEABLE and PGA_ICACHE_SYNCED
from ever being simultaneously set, and when the page's last mapping is
destroyed.

vm_page: Replace PGA_EXECUTABLE with PGA_PMAP_PRIV1
At present, PGA_EXECUTABLE is only used by the powerpc mmu_oea64 pmap.
The MI layer only accesses this flag to assert that it is clear when a
managed page is freed. Soon, we will need a similar, but not identical,
machine-dependent flag in the arm64 pmap. So, we rename this flag to
PGA_PMAP_PRIV1, simply saying that it is reserved for use by the pmap.
Each pmap can then define a name that best reflects its own meaning.
However, we still assert that this flag is clear when a managed page is
freed.
No functional change.

Pull probe fixes from Masami Hiramatsu:
- kprobes: Fix permanent hang when flushing the kprobe optimizer
Fix a deadlock when disabling kprobe optimization via sysctl or
debugfs where flushers hung waiting for optimizer_completion.
Replaced the completion with an optimizer_passes counter and
wait_var_event_mutex() under kprobe_mutex so concurrent flushers can
wait and wake up safely.
- fprobe: Terminate the fgraph_data list when the reservation is not
filled
Fix an issue where unused shadow stack data left uninitialized by
fprobe_fgraph_entry() was misparsed as stale fprobe headers on
return. Explicitly write a zero word to terminate the list and update
read_fprobe_header() to handle the zeroed slot properly.
