268e6cc2d8 Oops, this should have been in last commit.
Adds variable cil: current INTerrupt level.  This is part of the new
MP-safe spl algorithm.

50236db533 Made PEND_INTS default.
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.

4cabeed7a2 Attempt to make cy.c 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.

2c414e3eff Preperation for moving cpl into critical region access.
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).

8d1042dd0d To handle scsi RESERVATION CONFLICT properly in ahc driver.
Could somebody please update other drivers so that SCSI_RSVD (0x18)
to be handled just like SCSI_BUSY(0x08)?

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

4542c1cf5d Fix all areas of the system (or at least all those in LINT) to avoid storing
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.

79155dd871 The promised "better fix" for "Trap 9 When Boot SMP" problem.
We now tsleep() in kthread_init() between start_init()
and prepare_usermode() while waiting for ALL the idle_loop()
processes to come online.

6bb904da80 Add a spin lock that prevents the sequencer from attempting to add an
entry to the QOUTFIFO when it is full.  This should eliminate the
"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.
