[AArch64][PAC] Rework the expansion of AUT/AUTPAC pseudos (#169699)
Refactor `AArch64AsmPrinter::emitPtrauthAuthResign` to improve
readability and tune the conditions when `emitPtrauthDiscriminator` is
allowed to clobber address discriminator operands.
When resigning, do not clobber address discriminator register used for
authentication if it is also used for signing. Such clobbering would
prevent passing raw, 64-bit value as the new discriminator. Clarify
other corner cases of clobbering address discriminator operands.
Reuse `enum PtrauthCheckMode` instead of separate `ShouldCheck` and
`ShouldTrap` flags and drop its `Default` enumerator.
[mlir][bufferization] Avoid invalid memref.cast in to_buffer folding (#208973)
Fixes #202782
When folding bufferization.to_buffer(bufferization.to_tensor(...)), only
create a memref.cast if the source and destination memref types are
cast-compatible.
This avoids asserting on unranked memrefs with different memory spaces
and leaves the original bufferization ops in place instead.

[lldb] Fix TestSBValueSetTypeSyntheticOverride with libstdc++ (#210495)
My test added in #209056 assumed that a `CXXSyntheticChildren`
implementation for `std::vector` is readily available on all platforms,
that is not the case.
Do the simplest thing and remove this part of the test for now.
Fixes: https://lab.llvm.org/buildbot/#/builders/59/builds/35839

net-mgmt/monitoring-plugins: Update to 3.0.1
*) Security: fix a potential local privilege escalation in check_icmp,
which might be possible if check_icmp runs with setuid (the default)
*) Change: check_nt, check_ntp, check_nwstat and check_overcr were
removed upstream; check_ntp is replaced by check_ntp_time and
check_ntp_peer
*) Change: check_http is deprecated in favor of check_curl
*) Change: check_snmp now uses net-snmp natively instead of executing
snmpget
*) Change: generalized, mostly multi-line output for many plugins
*) Fix: check_curl now populates the DNS cache when the hostname is
resolved locally
Release Notes:

sys/powerpc64: encode PTCR PATS correctly
The PTCR PATS field stores log2(partition table size) - 12. Since
PATMEMSZ is a power of two, ffs(PATMEMSZ) is log2(PATMEMSZ) + 1; the
old expression wrote 5 for the 64 KiB table, describing 128 KiB to
Book3S v3 hardware.
Use ffs(PATMEMSZ) - 1 - 12 to express the intended log2 calculation
and encode the 64 KiB partition table as PATS == 4.

Import tzdata2026c from locally built tzdata2026cgtz.tar.gz
The real tzdata2026cgtz.tar.gz is not yet available (Europe in July!)
so I made a version which I think should be it. If there happen to
be any material differences when the real one appears, I will do an
update. Any irrelevant differences can just wait until next time.
Summary of changes in tzdata2026c (2026-07-08 10:23:58 -0700):
* Alberta’s 2026-03-08 spring forward was its last foreseeable clock
change, as it moved to permanent -06 thereafter.
* Although another TZDB release will likely be needed soon because
Northwest Territories will likely follow Alberta, the legal
formalities have not yet taken place.
* Morocco plans to move back to permanent UTC, without daylight
saving time transitions, on 2026-09-20 at 02:00.
* Changes to commentary.
[mlir][IR] Add SymbolUserTypeInterface (#198435)
This change adds SymbolUserTypeInterface, analogous to
SymbolUserAttrInterface, and extends SymbolTable verification to check
participating types.
Verification visits the types owned by an operation, (operand/result
types, block argument types, attribute-contained types, nested type
parameters) and checks each distinct type at most once, interrupting on
the first failure. Deduplication spans the whole symbol-table walk, so a
type used by multiple operations is checked only once.
Attribute (SymbolUserAttrInterface) verification also gets deduped the
same way.

properly handle qwx VIF DMA map allocation failures at attach time
qwx_attach() runs as a config_mountroot hook, which means errors returned
from this function will be ignored. Since returning errors is pointless,
change this function's return value type to void.
There is a theoretical risk that allocating the virtual interface's DMA
maps will fail. Allocate these maps earlier and avoid attaching the driver
if the maps cannot be allocated.
