992109b58e Get rid of DEVFS_ROOT 
it no longer has any effect.

SLICE is in some ways a replacement but is destined to also go away.

c0bab11dfe Make the devfs SLICE option a standard type option. 
(hopefully it will go away eventually anyhow)

3e425b968d Add changes and code to implement a functional DEVFS. 
This code will be turned on with the TWO options
DEVFS and SLICE. (see LINT)
Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes.

/dev will be automatically mounted by init (thanks phk)
on bootup. See /sys/dev/slice/slice.4 for more info.
All code should act the same without these options enabled.

Mike Smith, Poul Henning Kamp, Soeren, and a few dozen others

This code does not support the following:
bad144 handling.
Persistance. (My head is still hurting from the last time we discussed this)
ATAPI flopies are not handled by the SLICE code yet.

When this code is running, all major numbers are arbitrary and COULD
be dynamically assigned. (this is not done, for POLA only)
Minor numbers for disk slices ARE arbitray and dynamically assigned.

823833f19d Back out previous commit, obrien doesn't seem to be watching. The problem 
is that the previous commit spammed a hacked 2.2-stable onto -current,
deleting the DMA support etc.  (I guess that's one way of minimizing diffs
between -current and -stable.. :-] )

9c2fa4dbce In pre-devfs days, /dev/psm0 had always been a non-blocking 
device. But with devfs, currently, /dev/psm0 is the blocking device
and /dev/npsm0 is the non-blocking one.

DEVFS must stay consistent with the older behaviour.

17d925335f Minor typo in the wd driver. The manifestation of this bug 
is a tremendous perf decrease due to the disabling of advanced
features such as DMA, Ultra DMA, and 32bit mode.  This patch
might have been reported by someone else (I seem to remember
it.)
