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.

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

There's no need for extra state, so we use XS_BUSY for SCSI_RSVD too.

socket addresses in mbufs. (Socket buffers are the one exception.) A number
of kernel APIs needed to get fixed in order to make this happen. Also,
fix three protocol families which kept PCBs in mbufs to not malloc them
instead. Delete some old compatibility cruft while we're at it, and add
some new routines in the in_cksum family.

mod makes sure that the Natoma chipset is set into the correct mode. In
the case of my P6DNF, when booting a UP kernel, I see a substantial improvement
in the latency of certain operations. It appears that the cache hit
latency is curiously improved the most, per lat_mem_rd.
We now tsleep() in kthread_init() between start_init()

"Timed out while idle" problems that many have reported.
In truth, this is somewhat of a hack. Although are interrupt latency is
low enough that we should be able to always service the queue in time,
since each entry must be passed up to the higher SCSI layer for what can
be a large amount of processing (perhaps even resulting in a new command
being queued) with interrupts disabled, we need this mechanism to avoid
overflow. In the future, these additional tasks will be offloaded to a
software interrupt handler which should make this hack unnecessary.
uerror == 0 && lerror == EACCES, lowervp == NULLVP and union_allocvp
doesn't find existing union node and new union node is created.
Sicne it is dificult to cover all the case, union_lookup always
returns when union_lookup1() returns EACCES.
