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.

mkstemps() has been brought into 3-STABLE, so this isn't needed here

Optimize two cases in the MP locking code. First, it is not necessary
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.

Remove the non-functional "swap device" userland front-end to the
multiplexed underlying swap devices (/dev/drum). The only thing it did
was to allow root to open /dev/drum, but not do anything with it.
Various utilities used to grovel around in here, but Matt has written
a much nicer (and clean) front-end to this for libkvm, and nothing uses
the old system any more.
The VM system was calling VOP_STRATEGY() on the vp of the first underlying
swap device (not the /dev/drum one, the first real device), and using
the VOP system to indirectly (and only) call swstrategy() to choose
an underlying device and enqueue it on that device. I have changed it
to avoid diverting through the VOP system and to call the only possible
target directly, saving a little bit of time and some complexity.
In all, nothing much changes, except some scaffolding to support the
roundabout way of calling swstrategy() is gone.
Matt gave me the ok to do this some time ago, and I apologize for taking
so long to get around to it.
