32ad9cb531 Fix a few bugs with NFS and mmap caused by NFS' use of b_validoff
and b_validend.  The changes to vfs_bio.c are a bit ugly but hopefully
can be tidied up later by a slight redesign.

cb934d56d1 Don't keep addresses in mbuf chains. This should simplify the next round

00780cef44 Define our own version of DIRBLKSIZ instead of (ab)using ufs's value.
Use the same value of 512 (ufs actually uses DEV_BSIZE).  There are
too many versions of DIRBLKSIZ, one for ufs, one for ext2fs, one for
nfs, one for ibcs2, one for linux, one for applications, ... I think
nfs's DIRBLKSIZ needs to be a divisor of the directory blocks sizes
of all supported file systems.  There is also NFS_DIRBLKSIZ, which is
different from nfs's DIRBLKSIZ but is sometimes confused with it in
comments.

Removed a bogus #ifdef KERNEL that hid the tunable constants for nfs.
This came in undocumented with the Lite2 merge although it isn't in
Lite2.  It required more-bogus #define KERNEL's in fstat and pstat
to make the constants visible.

Restored a spelling fix from rev.1.17.

Removed duplicate #defines of all the the NFS mount option flags.

ports. This option will be automatically set/cleraed when mount is run
without/with the -n option.

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.

f438ae02f5 Improve the queuing algorithms used by NFS' asynchronous i/o. The
existing mechanism uses a global queue for some buffers and the
vp->b_dirtyblkhd queue for others.  This turns sequential writes into
randomly ordered writes to the server, affecting both read and write
performance.  The existing mechanism also copes badly with hung
servers, tending to block accesses to other servers when all the iods
are waiting for a hung server.

The new mechanism uses a queue for each mount point.  All asynchronous
i/o goes through this queue which preserves the ordering of requests.
A simple mechanism ensures that the iods are shared out fairly between
active mount points.  This removes the sysctl variable vfs.nfs.dwrite
since the new queueing mechanism removes the old delayed write code
completely.

This should go into the 2.2 branch.

6476c0d204 Even though this looks like it, this is not a complex code change.
The interface into the "VMIO" system has changed to be more consistant
and robust.  Essentially, it is now no longer necessary to call vn_open
to get merged VM/Buffer cache operation, and exceptional conditions
such as merged operation of VBLK devices is simpler and more correct.

This code corrects a potentially large set of problems including the
problems with ktrace output and loaded systems, file create/deletes,
etc.

Most of the changes to NFS are cosmetic and name changes, eliminating
a layer of subroutine calls.  The direct calls to vput/vrele have
been re-instituted for better cross platform compatibility.

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.
