[AArch64] Add support for B and H loads/stores in LoadStoreOptimizer (#180535)
This means the load/store optimizer can generate pre and post increment
versions of these instructions.
lagg: Make lagg_link_active() static
It is declared as static. Make the definition consistent with the
declaration.
It was ever fixed by commit 52e53e2de0ec, but the commit was reverted,
leaving it unfixed.
No functional change intended.
MFC after: 3 days
ZTS: update the relevant mmp test cases
- mmp_concurrent_import: added test case to verify that concurrent
import correctness. The pool may only be imported once.
- mmp_exported_import: an activity check is now required for pools
which were cleanly exported if the system and pool hostids don't
match.
- mmp_inactive_import: an activity check is now required for any
pool which wasn't cleanly exported, even if the system and pool
hostids match.
- mmp_on_uberblocks: updated expected uberblocks to take in to account
the value MMP_INTERVAL_DEFAULT is set too.
- mmp_reset_interval: reduce the number of iterations from 10 to 3.
This is sufficient to verify functionality and significantly speeds
up the test.

zhack: add "action idle" subcommand
In order to reliably test the multihost protection we need two (or more)
systems attempting to import the pool at the same time. Historically, we've
used ztest running in userspace to simulate an active pool and attempted to
import the pool with the kernel modules. This works but ztest is a bit
unwieldy for this and if it crashes for unrelated reasons it can result
in false positives.
All we really need is the pool imported in userspace so the MMP thread is
active and writing out uberblocks. We can extend zhack which already knows
how to import the pool read/write and add an option to leave the pool open
and idle.

zhack: add -G option to dump debug buffer
Add a -G option to zhack to dump the internal debug buffer on exit.
We were able to use the same code from zdb for this which was nice.

mmp: claim sequence id before final import
As part of SPA_LOAD_IMPORT add an additional activity check to
detect simultaneous imports from different hosts. This check is
only required when the timing is such that there's no activity
for the the read-only tryimport check to detect. This extra
safety chceck operates as follows:
1. Repeats the following MMP check 10 times:
a. Write out an MMP uberblock with the best txg and a random
sequence id to all primary pool vdevs.
b. Verify a minimum number of good writes such that even if
the pool appears degraded on the remote host it will see
at least one of the updated MMP uberblocks.
c. Wait for the MMP interval this leaves a window for other
racing hosts to make similar modifications which can be
detected.
d. Call vdev_uberblock_load() to determine the best uberblock
to use, this should be the MMP uberblock just written.

mmp: add spa_load_name() for tryimport
Tryimport adds a unique prefix to the pool name to avoid name
collisions. This makes it awkward to log user-friendly info
during a tryimport. Add a spa_load_name() function which can
be used to report the unmodified pool name.

mmp: move "Starting import" log message
Move the "Starting import" log message in to the import block so
it's matched with the "Fiinshed importing" debug message.

ports.cgi: do not display links to other categories
A port may be listed in several categories. Just show the categories,
don't create clickable links to https://cgit.freebsd.org/ports/tree/<category>
because the category could be a virtual one and does not exists in our
ports git repo.
mmp: further restrict mmp exported pool check
For a cleanly exported pools there exists a small window where
both systems may determine it's safe to import the pool and skip
the activity check. Only allow the check to be skipped when the
last imported hostid matches the systems hostid and the pool was
cleanly exported.

arm64: Have get_kernel_reg return void
It now panics when it's unable to find the register, so doesn't need
to return a status.

arm64: Panic if the ID register isn't known
This will allow for callers to be simplified & not need to check the
return status.
Keep the return type for now so this can be MFCd without breaking the

workflows/release-task: Use less privileged token for uploading release notes (#180299)
We were using one token for both pushing to the llvmbot fork and for
creating a pull request against the www-releases repository, since the
fork and the repository have different owners, we were using a classic
access token which has very coarse-grained permissions. By using two
separate tokens, we limit the permissions to just what we need to do the
task.
Also, at the same time run the release-documentation job in an
environment, so we can limit the accessiblity to these secrets.
