async callbacks. Note that ia64 callbacks might not be MPSAFE at the
moment. Note that powerpc doesn't seem to do async callbacks due to
the implementation being incomplete.

o Hook libpthread to the build on ia64. This is slightly out of
order, because the kernel still doesn't have all the support,
but that's not a problem in this case.
functions are derived from the swapctx() and restorectx() (resp)
from sys/ia64/ia64/context.s. The code is expected to be 99%
correct, but has not yet been tested.
Note that with these functions operating on mcontext_t, we also
created the foundation upon which we can implement getcontext(2)
and setcontext(2) replacements. It's not guaranteed that the use
of these syscalls and _ia64_{save|restore}_context() on the same
uicontext_t is actually going to work. Replacing the syscalls is
now trivially achieved.
This commit completes the ia64 port of libpthread itself (modulo
testing and bugfixes).
succeeds. There is a difference between how OLDCARD and NEWCARD deal
with their resources, and this code exposes that difference. I'm not
sure which behavior is correct, and will need to look into that in
more detail. However, it appears that we go ahead and allocate the
right thing in both cases that I have access to (CF cards, CDROM, and
external ata enclosures), so go ahead and ignore the failure to get
the resource for the other rid. There's already another check to make
sure that the actual allocation works correctly, and that should be
sufficient to catch cases that don't work.

o add back rx monitor support
o make WI_RID_SCAN_RES DTRT
o fix a bug handling zero-length RID requests (used by dstumbler to set
a zero-length SSID)
o make RID_SCAN_REQ DTRT
o add back WI_RID_OWN_SSID
o fix wi_scan_ap to take a channel mask and txrate (for prism cards)
These changes fix dstumbler -o (monitor mode). A minor change to dstumbler
is needed to get normal AP scanning mode to work right; this is preferred to
modifying the driver.

flag'ed INTR_MPSAFE. In ep_if_start(), use the IF_DEQUEUE macro to
grab the next mbuf to send, and use IF_PREPEND if the card is busy
and we actually can't handle it right now.
The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either. It was later assuming that IF_DEQUEUE would
give him this same mbuf.

This commit has two pieces. One half is the watchdog kernel code which lives
primarily in hardclock() in sys/kern/kern_clock.c. The other half is a userland
daemon which, when run, will keep the watchdog from firing while the userland

While here, provide empty, non-working, stubs for the context functions

least compile libkse from CVS sources. Real implementations will follow
soon.
minimize the amount and complexity of assembly code that needs to be
written. This way the core functionality is spread over 3 elementary
functions that don't have to do anything that can more easily and
more safely be done in C. As such, assembly code will only have to
know about the definition of mcontext_t.
The runtime cost of not having these functions being inlined is less
important than the cleanliness and maintainability of the code at
this stage of the implementation.
