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.

that the code might be reused).

at the point that it calls get_pv_entry(). Thus, pmap_enter()'s PV list
lock pointer must be passed to get_pv_entry() for those rare occasions
when get_pv_entry() calls reclaim_pv_chunk().
Update some related comments.
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).

It allows things like 'vidcontrol -T cons25 80x30' works as supposed,
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'.
