40cb9a942e Handle the "syncing VCHR vnode hang" problem a little differently; just
don't lock the vnode - it doesn't appear to ever be necessary for VCHR
vnode/inodes. This fixes a bug introduced in the previous commit that
caused tty timestamps to act strange (causing 'w' and 'finger' to show
the tty wasn't idle when it may have been for hours).

9f1fdb4af4 Tunnel driver is nmow capable of installing its own cdevsw[] entry,
with a little help from conf.c.  While e're at it, actually declare the
tunnel entry points to have the correct types.  This fixes PR #306.

4bd9e735a6 Correct name `cd9660' for MOUNT_CD9660 (but NB that this whole table

7d1fb8167a Part of Frank Durda IV's new matcd driver CD audio support.

e0949c1367 This is the new submission of the matcd driver. In addition to the
new driver code, there are diffs to several other existing files
on the system and a man page.

This version of matcd implements the rest of the key ioctls related to
playing audio CDs and reading table of contents information from any
type of disc.

This update also corrects several problems detected since the original
version 1(10) was released.  These include:
1.	Jordons report on the kernel -c string problem.
2.	A problem with the driver being confused by other types of
	devices located at addresses it probes.
3.	An old CD TOC wouldn't always be cleared after a disc change.
4.	Cleaned up code so -Wall yields no warnings on 2.0 and later.
5.	A problem with drive getting out of sync with the driver when
	changing between CD-Data and CD-DA.

There have only been two reports from the field relating to problems
so either the first release isn't really being used or doesn't have
many problems.

If there are any problems with this submission, please let me know.

a68a51bd80 Changes from John Dyson and myself:
Fixed remaining known bugs in the buffer IO and VM system.

vfs_bio.c:
Fixed some race conditions and locking bugs. Improved performance
by removing some (now) unnecessary code and fixing some broken
logic.
Fixed process accounting of # of FS outputs.
Properly handle NFS interrupts (B_EINTR).

(various)
Replaced calls to clrbuf() with calls to an optimized routine
called vfs_bio_clrbuf().

(various FS sync)
Sync out modified vnode_pager backed pages.

ffs_vnops.c:
Do two passes: Sync out file data first, then indirect blocks.

vm_fault.c:
Fixed deadly embrace caused by acquiring locks in the wrong order.

vnode_pager.c:
Changed to use buffer I/O system for writing out modified pages. This
should fix the problem with the modification date previous not getting
updated. Also dramatically simplifies the code. Note that this is
going to change in the future and be implemented via VOP_PUTPAGES().

vm_object.c:
Fixed a pile of bugs related to cleaning (vnode) objects. The performance
of vm_object_page_clean() is terrible when dealing with huge objects,
but this will change when we implement a binary tree to keep the object
pages sorted.

vm_pageout.c:
Fixed broken clustering of pageouts. Fixed race conditions and other
lockup style bugs in the scanning of pages. Improved performance.

36d79e32c9 Implement a simple hook (or hack?) to allow graphics device console
drivers to protect DDB from being invoked while the console is in
process-controlled (i.e., graphics) mode.

Implement the logic to use this hook from within pcvt.  (I'm sure
Søren will do the syscons part RSN).

I've still got one occasion where the system stalled, but my attempts
to trigger the situation artificially resulted int the expected
behaviour.  It's hard to track bugs without the console and DDB
available. :-/
