implementation. I took the NetBSD man page, and hacked it to, I hope,
to reflect the preliminary version of the bus space that Justin Gibbs
committed as part of the CAM integration in FreeBSD 3.0.
This isn't perfect, but it is better than we have now (which is, ahem,
nothing). Please coordinate changes to the file through me through
the 6.0 release.

function pointer to the vga render dispatch table and initialized it with
vga_nop. The problem is that vga_nop() is a varargs function, and the
table declares a non-varargs function pointer. On amd64 (and I think ppc),
mixing varargs and non-varargs function pointers is fatal.
Change vga_nop() and gfb_nop() from varargs to non-varargs do-nothing
functions. This stops the stack corruption that only happened on amd64.

used to ensure that we weren't exiting the syscall with a lock still
held. This wasn't safe, however, because we'd already executed a vput()
and on a loaded system the vnode may have been free'd by the time we
assert. This functionality is also handled by the td_locks assert in
userret, which doesn't tell you what the syscall was, but will at least
panic before you deadlock.

anyway and it's not used outside of vfs_subr.c.
- Change vgonel() to accept a parameter which determines whether or not
we'll put the vnode on the free list when we're done.
- Use the new vgonel() parameter rather than VI_DOOMED to signal our
intentions in vtryrecycle().
- In vgonel() return if VI_DOOMED is already set, this vnode has already
been reclaimed.

this is happening at the moment and sometimes causing panics later on the
package cluster when we bremfree() a buf whose delayed bremfree() did not
previously happen.

most of the code to deal with them has been dead for sometime. Simplify
the code by doing an insert sort hinted by the current head position.

on an IPv4 packet as these variables are uninitialized if not. This used to
allow arbitrary IPv6 packets depending on the value in the uninitialized
variables.
Some opcodes (most noteably O_REJECT) do not support IPv6 at all right now.

I introduce a very small race here (some file system can be mounted or
unmounted between 'count' calculation and file systems list creation),
but it is harmless.

Move detaching the ifnet from the ifindex_table into if_free so we can

MFC note: When MFC'd, don't MFC mention of work not yet MFC'd.
It can be used to panic the kernel by giving too big value.
Fix it by moving allocation and size verification into kern_getfsstat().
This even simplifies kern_getfsstat() consumers, but destroys symmetry -
memory is allocated inside kern_getfsstat(), but has to be freed by the
caller.
