receiving interface in the packet header of every mbuf.
The interface pointer should now be retrieved when necessary with
if_get(). If a NULL pointer is returned by if_get(), the interface
has probably been destroy/removed and the mbuf should be freed.
Such mechanism will simplify garbage collection of mbufs and limit
problems with dangling ifp pointers.
Tested by jmatthew@ and krw@, discussed with many.

atime and mtime are UTIME_OMIT (at least for ufs, tmpfs, and ext2fs), and
to correctly handle a timestamp of -1.

- rename uiomove() to uiomovei() and update all its users.
- introduce uiomove(), which is similar to uiomovei() but with a size_t.
- rewrite uiomovei() as an uiomove() wrapper.

purge the vnode from the namecache first. This prevents cache_purge()
from later getting confused and trying to cache_zap() a namecache entry
multiple times over, due to cache_zap() believing that the entry does not
need to be removed from the vnode destinations queue.

members to 64bit types. Assign new syscall numbers for (almost
all) the syscalls that involve the affected types, including anything
with time_t, timeval, itimerval, timespec, rusage, dirent, stat,
or kevent arguments. Add a d_off member to struct dirent and replace
getdirentries() with getdents(), thus immensely simplifying and
accelerating telldir/seekdir. Build perl with -DBIG_TIME.
Bump the major on every single base library: the compat bits included
here are only good enough to make the transition; the T32 compat
option will be burned as soon as we've reached the new world are
are happy with the snapshots for all architectures.
DANGER: ABI incompatibility. Updating to this kernel requires extra
work or you won't be able to login: install a snapshot instead.

vector setup that has questionable features (that have, as far as I can
tell never been used in practice, atleast not in OpenBSD), remove all
the gunk and favor a simple struct full of function pointers that get
set directly by each of the filesystems.
Removes gobs of ugly code and makes things simpler by a magnitude.
The only downside of this is that we loose the vnoperate feature so
the spec/fifo operations of the filesystems need to be kept in sync
with specfs and fifofs, this is no big deal as the API it self is pretty
static.
Many thanks to armani@ who pulled an earlier version of this diff to
current after c2k10 and Gabriel Kihlman on tech@ for testing.
Liked by many. "come on, find your balls" deraadt@.

sync a few comments to reality (or remove them), remove the cn_hash member
from struct componentname, spacing.

no binary change apart from nfsm_reqhead() which is clearly correct.

also make the rexmit timeout per nfsmount, and make sure to start/stop the
timer appropriately.
now the nfs_timer() only fires if there is work todo, not always at nfs_ticks
(it did, even if there where no nfsmounts in the system!).

each mount, and when work is "found", peg an aiod to that mount todo the
I/O. Make nfs_asyncio() a bit smarter when deciding when to do asyncio
and when to force it sync, this is done by keeping the aiod's one two lists,
an "idle" and an "all" list, so asyncio is only done when there are aiods
hanging around todo it for us or are already pegged to the mount.
Idea liked by at least beck@ (and I think art@).
Extensive testing done by myself and jasper and a few others on various
arch's.

but extensive performance benchmarking done by myself and jasper@
has shown that it doesn't help, at all - even on vaxens and in some
cases it makes things significantly slower.

to keep the data munging "state" into an nfsm_info structure. Each
function now has this structure on its stack, and it and its members
are now passed around so that the macros/functions can work there magic.
this will make removing the nfsm_* macros way easier.
Idea/code picked up from DragonflyBSD.
Tested by krw@, jacekm@ and myself.
OK blambert@.

OK blambert@

which is exactly what the macro does.
Macro's that are nothing more then:
#define FUNCTION(arg) function(arg)
are almost always pointless and should go away.

Agreed by many.

mtime, gives us better granularity, helps with cache consistency.

requires well-formed mbuf chains to work. Existing function name is now
a wrapper to this interface. Much, much more work to follow which will
build on this.
Truly change we can believe in.
ok thib@, who would have preferred this in two commits, but I'm impatient :)
testing on multiple arches (i386, arm, amd64, and sparc64 at least) by many,
thanks to all who did so
