Make sure the stack is aligned when delivering signals.
Fixes the t_signal_and_sp:misaligned_sp_and_signal and
t_signal_and_sp:signalsp_sigaltstack test cases on m68k.
virtio(4): combine virtio and virtio_mmio man pages.
While here, add missing VirtIO devices and improve grammar and text.
virtio_mmio.4 was present in the source tree but never installed.
mount_lfs: Build fix: s/unreachable()/__unreachable()/
<stddef.h> only declares unreachable() for C23 or later.
Here, as <sys/cdefs.h> is already being included, just
use one of its definitions directly, rather than attempting
to do so indirectly via <stddef.h>
This can be changed to anything else that works of course.
mount_lfs(8): Add unreachable() to fix clang build.
dependall ===> sbin/mount_lfs
/home/source/ab/HEAD-llvm/src/sbin/mount_lfs/mount_lfs.c:319:1: error: function declared 'noreturn' should not return [-Werror,-Winvalid-noreturn]
The only two cases in invoke_cleaner are already handled, so the rest
should be unreachable.

New Features#
Disclose active Negative Trust Anchors with Extended DNS Error 33.
A Negative Trust Anchor (RFC 7646) turns off DNSSEC validation for a
domain, so a name that would normally fail validation resolves instead. named
now marks such answers with Extended DNS Error code 33, "Negative Trust
Anchor", so operators can see at a glance when a response came back only
because an NTA was in effect. [GL #6268]
Feature Changes#
Speed up RPZ policy zone updates.
RPZ updates used to be applied one small step at a time, adding overhead on
large policy zones. Updates are now applied as a single batch, improving
update performance for large RPZ zones, at the cost of no longer overlapping
with concurrent updates. [GL #5787] [GL #6270]
Bug Fixes#
Ensure NSEC authority does not cross zonecut boundary.

ptrace(2): Fix compat32 register set types in previous.
Not always `struct reg32' or `struct fpreg32', notably on arm32 --
make sure to say `process_reg32'/`process_fpreg32'/`process_dbreg32'.

Mark inode modified in lfs_putpages, when there are dirty pages.
This ensures the inode is written after the pages, avoiding a situation

Sort the list of segments entered with -s so they appear in the output in

execve(2): Set p_stackbase in execve_runproc, not execve_loadvm.
execve_loadvm must not have side effects on the running process for
two reasons:
1. If execve(2) fails, it has to be able to back out and return to
the calling process. For example, the shell will execute the
first of a series of candidate paths that works when it searches
$PATH, and if one fails, it has to be able to move on to try the
next.
2. The caller may be the _parent_ process -- this is the case when
we're in posix_spawn.
Instead, it must be set in execve_runproc, after we're committed to
the exec and can't back out -- and we're definitely operating on the
process that is executing a new image, not on its parent!
