Split pyro_intr_establish() into a stub which locates the softc
from the pdb (used by pyro routines) and pyro_intr_establish_sc()
which does the work.
In pyro_softc, save a pointer to our pyro_intr_establish_sc().
This allows us to call the correct pyro_intr_establish_sc() from devices
that use pyro interrupts but are not (pci) children of pyro, i.e.
ebus @ mainbus and firei2c*.
kern: Nix SS_ISABORTING.
This was a vestige of an earlier revision of the .fo_restart
mechanism; it is never set by anything in the kernel, it has been
supplanted by SS_RESTARTSYS, and it serves no further purpose.
t_fdrestart: Test socket connect and accept too.
The logic for connect, it turns out, is missing .fo_restart tests.

Lost this in a round of refactoring, and it just kinda worked by
accident, oops!

return false always to keep it in procedures returns.
Unbreak build when KGDB is defined.
Add extern reference to kernel_pmap_
Remove mutex calls since no mutex is present in the pmap struct,
since pseg_get() has its own internal locking logic.
Import jemalloc 5.4.0 (previous was 5.3.1)
* 5.4.0 (Sep 17, 2026)
This release contains over 160 commits, focusing on the technical debts
cleaning including refactorings, bug fixes, test coverage improvement, and
option cleanups. The release also includes portability improvements per
upstream issues report.
New features:
- Add `EXTENT_ALLOC_FLAG_PINNED` so custom extent-allocation hooks can
mark non-reclaimable mappings, such as HugeTLB pages, for preferential
reuse outside the decay and purge pipeline. Add the mallctl interfaces
`stats.pinned`, `stats.arenas.<i>.pinned`,
`stats.arenas.<i>.extents.<j>.npinned`,
`stats.arenas.<i>.extents.<j>.pinned_bytes`, and
`stats.arenas.<i>.mutexes.extents_pinned.{counter}` to report
pinned-memory usage and mutex statistics. (@binliu19: be2de8cc)
- Allow resuming per-CPU arena selection via `thread.arena`.

mips: tag all the stub functions as __noubsan
When built with UBSAN the stub functions change to the point that the
mips_fixup_addr code doesn't understand the instructions involved.
Apply __nousbsan to avoid this.

t_mkfifo: Bump timeouts a little bit to exercise the race better.
Currently on the releng testbed, the parent's open() call is not
failing with _any_ EINTR, presumably because (a) the child is opening
the fifo before any itimer alarms fire and then (b) signal no longer
causes the parent's open() to fail once the child has opened the other
end of the fifo. So let's give the parent a bit more of a head start,
and run the race a little longer.

interruption
re(4): fix mangled TX queue on DMA map loading errors
Do not advance the TX queue producer index when bus_dmamap_load_mbuf()
fails.
The producer index must advance only after a packet has been
successfully committed to a TX queue entry. Advancing it on a
map loading error leaves a hole in re_txq[], while re_txq_free()
still counts only successfully queued packets.
re_txeof() assumes that all outstanding TX queue entries from
re_txq_considx are contiguous, so such a hole can make it process
an unused entry and corrupt the TX queue accounting.
This bug was introduced by my re_encap() -> re_start() refactoring
in rev. 1.59 back in 2006. Sorry it took ~20 years to notice it.
Should be pulled up to netbsd-11 and netbsd-10.
