- Replace overly-complicated (and buggy) -a logic with a much simpler
version: -a causes all interrupts to be displayed, otherwise only
those that have occurred are displayed. This removes the need for
any MD code.
- Instead of just making sure intrcnt is large enough, figure out the
exact size it needs to be. We derive nintr from this number, and we
don't want to risk printing garbage. Note that on sparc64, we end up
printing garbage anyway because the names of non-existent interrupts
are left uninitialized by the kernel.
Tested on: alpha, i386, sparc64
only turned up when running mac_test side by side with a transitioning
policy such as SEBSD. Make the NULL testing match
mac_test_execve_will_transition(), which already tested the vnode
label pointer for NULL.

- Move loader relocation up to 0x1C00000. This is in line with OSX bootx,
and allows more space for boot-time modules/ramdisks without conflicting
with OpenFirmware's use of RAM
- OpenFirmware returns overlapping memory regions. Use a simple
brute force algorithm to merge these into non-overlapping
regions. This fixes bugs in reporting of available memory
and also prevents pages from being added twice in the VM system.
such that 'ispcvt' can build. Unforunately 'ispcvt' is needed in order for
/etc/rc.d/syscons to run. This fixes the bug where I could not get my
keymap effective at boot.
likely to be non-zero. When leaving the cancellation point, check
the return value against -1 to see if cancellation should be
checked. While I'm here, make the same change to connect() just
to be consisitent.

turnstile_unpend(). A racing thread that does not have TDI_LOCK set may
either be running on another CPU or it may be sitting on a run queue if it
was preempted during the very small window in turnstile_wait() between
unlocking the turnstile chain lock and locking sched_lock.
case of a turnstile having no threads is just one instance of the more
general case where the thread we are examining has been partially awakened
already in that it has been removed from the turnstile's blocked list but
still has TDI_LOCK set. We detect that case by checking to see if the
thread has already had a turnstile reassigned to it.
