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.

when get_pv_entry() calls reclaim_pv_chunk().

across in_gif_output() and in6_gif_output() anyway, and once it is held
across those it might as well be held for the entire loop. This simplifies
the code and removes the need for the custom IFF_GIF_WANTED flag (which
belonged in the softc and not as an IFF_* flag anyway).

and allows 'allscreens_flags="-T cons25 80x30"' in /etc/rc.conf too.

According to the AMD manual the whole range from 0x09 to 0x1f are NOPs.
Intel manual mentions only 0x1f. Use only Intel one for now, it seems
to be the one actually generated by compilers.
Use gdb mnemonic for the operation: "nopw".

relative to the start address (unless the start address is 0, which is
not the case).
This is currently not a problem because all powerpc architectures are
using loader(8) which passes metadata to the kernel including the
correct `endkernel' address. If we don't use loader(8), register 4
and 5 will have the size of the kernel ELF file, not its end address.
We fix that simply by adding `kernel_text' to `end' to compute
`endkernel'.
