0d7d0fcf29 Convert a couple of large allocations to use zones rather than malloc
for better packing.  This means that we can choose better values for the
various hash entries without having to try and get it all to fit within
an artificial power of two limit for malloc's sake.

e4a57cb44a Add missing arg to vget().. Serves me right for committing a 2.2 patch to
-current without testing it there.. :-(

9733f8ee44 Hold a reference to the vnode during the sillyrename cleanup. If we block
in nfs_vinvalbuf() or the nfs_removeit(), we can have the nfsnode reallocated
from underneath us (eg: replaced by a ufs 'struct inode') which can cause
disk corruption ('freeing free block' when di_db[5] gets trashed).
This is not a cheap fix, but it'll do until the nfsnodes get reference
counting and/or locking.

Apparently NetBSD have a similar fix (apparently from BSDI).

I wish all PR's had this much useful detail. :-)

a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.
Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

99448ed11d Change the M_NAMEI allocations to use the zone allocator. This change
plus the previous changes to use the zone allocator decrease the useage
of malloc by half.  The Zone allocator will be upgradeable to be able
to use per CPU-pools, and has more intelligent usage of SPLs.  Additionally,
it has reasonable stats gathering capabilities, while making most calls
inline.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

2f9bae59d6 Moved the fsnode MALLOC to before the call to getnewvnode() so that the
process won't possibly block before filling in the fsnode pointer (v_data)
which might be dereferenced during a sync since the vnode is put on the
mnt_vnodelist by getnewvnode.

f5526ddb48 Implemented an nfs_node hash list lock, similar to what was implemented
in ffs_vget(), and for the same reason: to prevent a race condition that
results in duplicate vnodes/NFSnodes being allocated.

a62dc40654 Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount).  The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server.  It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs.  Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.

b5e8ce9f12 Add and move declarations to fix all of the warnings from `gcc -Wimplicit'
(except in netccitt, netiso and netns) and most of the warnings from
`gcc -Wnested-externs'.  Fix all the bugs found.  There were no serious
ones.

6ae324074a This is a bunch of changes from NetBSD. There are a couple of bug-fixes.
But mostly it is changes to use the list-maintenance macros instead of
doing the pointer-gymnastics by hand.

advlock mechanism, and not doing so results in random system crashes.
