bwrite(). VFS needs to know about EFAULT from uiomove() and does not
care much that partially filled block writeback after EFAULT was
successfull. Early return without error causes short write to be
reported to usermode.

Asus laptops. It is alike to acpi_asus(4), but uses WMI interface instead
of separate ACPI device.
On Asus EeePC T101MT netbook it allows to handle hotkeys and on/off WLAN,
Bluetooth, LCD backlight, camera, cardreader and touchpad.
On Asus UX31A ultrabook it allows to handle hotkeys, on/off WLAN, Bluetooth,
Wireless LED, control keyboard backlight brightness, monitor temperature
and fan speed. LCD brightness control doesn't work now for unknown reason,
possibly requiring some video card initialization.

important for those that use -DNO_CLEAN routinely, since it will prevent
installing stale stuff, and even more important when the port is upgraded
to a newer version. When the user doesn't use -DNO_CLEAN, this will create
an infinitesimal amount of extra work, but won't hurt anything.
This is necessary because the ports tree has flags that prevent the ususal
'update the build if newer source files exist' logic from doing what it
would do in the base.
as an EDMA check function.
For the AR9003 and later NICs, different TX/RX DMA and descriptor handling
code will be conditional on the EDMA check.

The function isascii_l() is not in POSIX even though isascii() is,
probably because isascii() is marked as obsolete. The other functions,
like digittoint_l() and ishexnumber_l(), are FreeBSD-specific just like
their non-_l versions.
we need to pass BIO_DELETE requests down to providers that support
it. Also, we need to announce our support for BIO_DELETE to upper
consumer. This requires:
- In g_mirror_start() return true for "GEOM::candelete" request.
- In g_mirror_init_disk() probe below provider for "GEOM::candelete"
attribute, and mark disk with a flag if it does support BIO_DELETE.
- In g_mirror_register_request() distribute BIO_DELETE requests only
to those disks, that do support it.
Note that we announce "GEOM::candelete" as true unconditionally of
whether we have TRIM-capable media down below or not. This is made
intentionally, because upper consumer (usually UFS) requests the
attribite only once at mount time. And if user ever migrates his
mirror from HDDs to SSDs, then he/she would get TRIM working without
remounting filesystem.

running with multiple SoCs compiled in very well anyway, so this just
wastes space. As more and more SoCs arrive in the tree, it is better
to edit one master file that builds them all than many board files.
* Add a new ANI variable, for AR9003 and later chips;
* The AR9003 and later series chips support two RX queues now, so start
down the road of supporting that;
* Add some new TX queue types - uAPSD is possible on earlier chips,
but PAPRD is relevant to AR9003 and later.

Now that we have an illumos vendor area, import the llquantize
test files directly from there to make it easier to track the
code provenance.
Special thanks to Martin Matuska for populating the illumos
vendor area.

living process as a zombie and refuses to kill it. The cause is that
the code masks ki_stat with SZOMB to compare with SZOMB, but ki_stat
is not a mask.
