o Delete pcic1 from NEWCARD
o Add explicit resource hints to pcic0
o Get attach working with newbus, kinda (it does all the newbus stuff,
but doesn't try to attach the pccard yet, too many panics).
o Disable ie0 and le0 in NEWCARD config. There appears to be a bug in
the isa_compat code wrt memory conflicts with newbus drivers for
reasons unknown.
o Minor cleanups.
to use a locked cmpexg when unlocking a lock that we already hold, since
nobody else can touch the lock while we hold it. Second, it is not
necessary to use a locked cmpexg when locking a lock that we already
hold, for the same reason. These changes will allow MP locks to be used
recursively without impacting performance.
Modify two procedures that are called only by assembly and are already
NOPROF entries to pass a critical argument in %edx instead of on the
stack, removing a significant amount of code from the critical path
as a consequence.

linked list to store the callbak routines. The patch converts the
lists to queue(3) TAILQs, making the code slightly clearer and ensuring
that callbacks are executed in FIFO order.
Man page also updated as necesary.

Note that we are counting time spent in software interrupt handlers as
interrupt time, so this invalidates the i386 meaning of intr_nesting_level.

that breaks if you try and compile a kernel before building world, as
is presently required to get past the signal changes. I don't
particularly like doing this, but at least it will mean that a 'make world'
will activate the gcc 2.95.2-specific option in bsd.kern.mk.
