[VPlan] Skip VPInst where mask is only operand in chain in isUsed (NFC) (#206286)
Update isUsedByLoadStoreAddress o skip VPInstruction where the operand
in the use chain is only used as mask. Those do not contribute to the
load address, so should not force scalarization.
Fixes a regression with f2459f9e
(https://github.com/llvm/llvm-project/pull/196842).
Strip leading dots as we do trailing dots from domains
Seems some routers do this and this breaks unbound at least.
Based on a patch from Dag-Erling Smørgrav <des at FreeBSD.org>
[X86] Add target verifier
Add an X86 TargetVerify and register it by triple so the
TargetVerifierPass dispatches to it for X86 modules. It performs no
checks yet; the subtarget-dependent checks are added in a follow-up.
[Target] Add target-independent TargetVerifier dispatcher
Introduce a target-dependent IR verification framework that can be run
from target-independent locations.
TargetVerify is a base class each backend subclasses to check a function
for constructs that are invalid for a particular target. Backends
register a factory keyed by Triple::ArchType via registerTargetVerify(),
typically from their LLVMInitialize<Target>Target().
TargetVerifierPass (registered as "target-verifier") is the dispatcher:
it reads the module triple and, if a verifier is registered for that
architecture, runs the generic IR verifier followed by the target's
TargetVerify. It is a no-op for targets that have not registered a
verifier, so it is safe to schedule from generic, target-independent
pipelines (e.g. `opt -passes=target-verifier`).
zio_ddt_write: compute have_dvas after taking dde_io_lock
In zio_ddt_write(), have_dvas and is_ganged were computed before
dde_io_lock was taken. A concurrent zio_ddt_child_write_done() error
path calls ddt_phys_unextend() under dde_io_lock, which can zero
DVA[0] while another thread is between computing have_dvas and taking
dde_io_lock. That thread then uses the stale have_dvas=1 to call
ddt_bp_fill(), copying the zeroed DVA into the BP. A zero DVA resolves
as a hole, producing blocks that read back as zeros with no checksum
error (silent data corruption).
Fix by moving have_dvas and is_ganged computation to after dde_io_lock
is taken, so they always reflect the current state of dde->dde_phys.
Regression introduced by a41ef36858 ("DDT: Reduce global DDT lock
scope during writes").

Fix race between device removal completion and pool export
vdev_remove_complete() finalizes a device removal in two phases under
the spa lock framework. Between the two phases it called
spa_vdev_exit(), which drops both the config locks (SCL_ALL) and
spa_namespace_lock and blocks on a txg sync. By that point
vdev_remove_replace_with_indirect() has already set svr->svr_thread =
NULL, and that is the only thing the export path (spa_export_common()
-> spa_async_suspend() -> spa_vdev_remove_suspend()) waits on. Once the
namespace lock is dropped, a concurrent export or destroy can acquire
it and set spa->spa_export_thread. When the removal thread re-enters
for its second phase via spa_vdev_enter(), it trips the
ASSERT0P(spa->spa_export_thread) assertion.
Hold spa_namespace_lock across both phases instead of dropping and
re-taking it: the intermediate spa_vdev_exit() becomes
spa_vdev_config_exit(), which drops only SCL_ALL and syncs the txg
while keeping the namespace lock held, and the second spa_vdev_enter()
becomes spa_vdev_config_enter(). Because the namespace lock is never

lang/gcc1[2-6]: actually fix build on powerpc64le/CURRENT
Without this patch, gcc attempts to enable support for IBM long double,
when IEEE long double is enabled, which is wrong. Allow to only
specify IEEE long double.
The whole patchset for IEEE long double on FreeBSD/powerpc64le
is being upstreamed at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=126012.
CI: Increase default watchdog NMI timeout on Linux
When the watchdog driver is configured and enabled an NMI will be
generated when the watchdogd process fails to regularly reset the
watchdog timer. Given the heavily virtualized and potentially
over-subscribed nature of the CI environment increase the default
timeout to 120 seconds (normally defaults to 30 seconds).

Pull pwm fixes from Uwe Kleine-König:
"Two more fixes that I managed to put into the public branch merged
into next before my first pull request but missed to include them in
it.
The first change is a relevant change that fixes misconfigurations due
to a variable overflow. The second is only cosmetic but very obviously
an improvement"

t_mbstowcs: Mark UTF-8 test cases xfail.
mbrtowc fails to reject invalid (legacy 5/6-byte) UTF-8.
Need to split this test up into:
1. correctly decoding the valid inputs
2. correctly rejecting the invalid inputs
Also don't stop at the first failing test in t_mbrtowc; keep going to
test everything, for better diagnostics at the end in the test
report.
As with t_mbrtowc, this should be split into multiple parts, TBD.
