free list problem. Also, the vnode age flag is no longer used by the
vnode pager. (It is actually incorrect to use then.) Constructive
feedback welcome -- just be kind.
pause before attempting to reset the sequencer address. Remove the
loop checking to see if the address has gone to zero since it is
unnecessary
Adjust the abort SCB timeouts back up to 2 seconds where they should
be.
Fix an oversight in the removal of the bus reset settle code where
we might not run the queue of completed commands.
Remove an unecessary call to ahc_run_done_queue in ahc_reset_current_bus.

Made NEW_STRATEGY default.
Removed misc. old cruft.
Centralized simple locks into mp_machdep.c
Centralized simple lock macros into param.h
More cleanup in the direction of making splxx()/cpl MP-safe.
I have no way of testing this one, first SMP/cy user please let me know...
It is my belief that sio and cy are the only FAST_INTR() ISRs. If this
is a bad assumption please educate me.
Several new fine-grained locks.
New FAST_INTR() methods:
- separate simplelock for FAST_INTR, no more giant lock.
- FAST_INTR()s no longer checks ipending on way out of ISR.
sio made MP-safe (I hope).
2.3.0 -> 2.3.1 changes, but I seem to recall that there are certain
"issues" with 2.3.1 (I'm not sure if it's just pppd or the whole lot, I
am not quite that far). The present pppd seems to work with it just fine
for the time being.
Among the changes are that zlib (aka LZ77 aka deflate aka gzip) compression
is implemented as well as the original compress(1) LZW style.
same syscall number as NetBSD/OpenBSD. The getpgid() came from NetBSD
(I think) originally, but it's basically cut/paste/edit from the other
simple get*() syscalls.
VM systems usage of the kernel lock (lockmgr) code. This is a first
pass implementation, and is expected to evolve as needed. The API
for the lock manager code has not changed, but the underlying implementation
has changed significantly. This change should not materially affect
our current SMP or UP code without non-standard parameters being used.
