arm64: Fix and rename midr_check_var_part_range()
At the lowest and highest variants in the specified range,
midr_check_var_part_range() was comparing the part number, rather than
the revision, against the bounds. In other words, the "Y" in "rXpY"
should be compared to CPU_REV() instead of CPU_PART(). Apply this
correction, and rename the function to midr_check_var_rev_range() to
better reflect the field that we are checking.

bhyve: Fix virtio-input event array resizing
Use the new array size when calling realloc(). Note that this queue
stores events read from a host evdev device, i.e., it is not
guest-controlled.
While here, use the cdefs.h __unused macro and use them correctly, i.e.,
don't mark "arg" as unused when it isn't.

inotify: Open target the directory when adding a watch
When an application uses inotify to watch a directory,
vn_inotify_add_watch() reads the directory entries and does a name
lookup so as to induce the filesystem to create namecache entries.
Some filesystems expect the directory to be opened before VOP_READDIR
can be called, so do that.

makefs/zfs: count "." in the link count and size of dataset roots
The root directory of a dataset is populated from an fsnode that is the
"." entry of the staging directory, and its children are the siblings of
that node, so the loop that computes the link count and the size of the
directory (which expects "." among the children, as the nodes of the
other directories have) never counts it. The link count of the root of
every dataset is one less than it should be (1 for an empty dataset
instead of 2, 19 instead of 20 for a root with 18 subdirectories), and
so is its size.
fts(3) trusts the link count of the directories of ZFS when called with
FTS_NOSTAT and FTS_PHYSICAL: it stops looking for subdirectories once it
has seen as many as the link count says, and does not descend into the
ones it did not look at. As a result find(1), and rm(1) when it does
not need to stat the entries, silently skip directories of a pool made
by makefs. On a root filesystem made by makefs, find / does not list
/etc at all.

sound examples: trigger dsp devices via syncgroup
Triggering is only needed if device is in mmap mode, and in mmap example
the device is triggered as part of syncgroup. For non-mmap mode,
triggering is not needed at all. Triggering mmap'ed device too early
would start the IPTR/OPTR counters and that would cause those pointers
to be out of sync, so let syncgroup do the triggering once the device is
fully configured and ready for capture and playback.

Add loongarch64 as an optional boot-test.sh arch
D59889 brings up a FreeBSD/loongarch64 EFI loader, none of it in
this tree yet. Add a disabled config entry (excluded from -A, usable
via -a once the port lands) using the confirmed QEMU virt/la464
recipe; hw/loongarch/virt.c defaults to virtio-blk/net, so the
existing generic EFI+GPT builder needs no arch-specific QEMU code.
loongarch64 has never had a FreeBSD release, so
install_minimal_userland's ISO extraction can never find one. Split
it into ISO and installworld-cross-build paths, selected by a new
no_release capability, so archs without a release can still get a
minimal userland.

nvmecontrol: Use admin device for admin-passthru
When we're doing admin-passhtru, we need to use the admin device, not

translate that to nvmeY for this command for the admin-passthru command,
but not the io-passthru command. Note namespace nuance in man page.

nvmecontrol: select format by sector size
Add automatic selection of lbaf value based on a single sector size. The
lbas (the data sector size) is selected based on the power of 2 in the
sector size, and the metadata size is selected by the remainder. If an
lbaf matches these values is used, otherwise we exit with an error.
When there's a tie, we prefer the higher performance.
Manual selection of these values remains as well for times when we
select incorrectly.
