Peter Dufault
f29b7a5d14 1. Change driver signatures to full signature for slice support. 
2. Add "pt" (processor type) driver.
3. Add "worm" (Write Once) driver for Jordan.

c79eac4c4c Weak symbol support from NetBSD. This should bring us in sync with the 
NetBSD ld code except for local changes for dlopen() and friends and
the hashing on the minor value of the shlibs.  We should be binary
compatible now with all their libraries.

Obtained from: NetBSD

9bd1697199 Added some more of John's "anti-chatter" fixes - set the page activation 
count to 0 after activating the page; the previous behavior biased the
pages too high in some cases.

Moved most handling of the compatibility slice to dsopen().

Report i/o errors.

2973a0eba4 Don't warn about missing labels for non-BSD slices. 
Don't print debugging messages by default.

Initialize the compatibility slice here and not in the machine-dependent
code.

Fix initialization of the label for the whole disk slice.

Make it clear that write protection of labels doesn't apply when there is
no label.

17fb427c08 Fake the geometry to be 32 sectors * 64 heads * (vn->sc_size / 2048) 
cylinders instead of vn->sc_size * 1 * 1.

af78195e00 Reduced loopback MTU to 16k to work around a miriad of problems with it 
set near or above 32k (likely caused by 16bit signed word overflow). 16k
actually (surprizingly) has higher performance than other values I tested.

252e349211 Reduce burst length to 4 DWORDs for now, since there seem to 
be 486 chip sets that can't tolerate bursts > cache line size.
This should really made dependent on the particular buggy
chip sets, but for now we'll play safe ...

37fda94006 Make 'config [kernel] swap generic' work again. It would seem that 
'matcd' has taken over the position and major number of 'pcd,' so
swapgeneric.c needs to be updated accordingly. (It was still looking
for pcd.h.)

e8dfeb8828 Some people have complained that they were unable to boot the 
Feb. 10th snapshot. The keyboard probe in the bootblock seems to
have been singled out as the cause of these problems, so I've beefed it
up alittle. This pushes us right up to the edge of the size limit:
the second stage boot is now 7152 bytes in size, just 8 bytes under
the wire. On the other hand, the new probe now does almost exactly
what syscons does, so hopefully this will do the trick. It seems
to work properly on my hardware, but then so did the old probe.

e902ae382a Remove unused variables, and move some inside of DEBUGDO to quite up 
compiler.
Be carefull about over usage of volatile, it really killed performance
in a few areas and there was a better place to make things volatile in
almost all cases.  The driver can now receive at full speed without RNR
errors.

f919ebde54 Various changes from John and myself that do the following: 
New functions create - vm_object_pip_wakeup and pagedaemon_wakeup that
are used to reduce the actual number of wakeups.
New function vm_page_protect which is used in conjuction with some new
page flags to reduce the number of calls to pmap_page_protect.
Minor changes to reduce unnecessary spl nesting.
Rewrote vm_page_alloc() to improve readability.
Various other mostly cosmetic changes.
