Log Message:
Since cpu_switch (aka Swtch) is now called at splsched() with sched_lock
locked, cpu_exit needs to do that too.  Since in the lock debug case we
have to use a CALLS which wipes out R0-R6, change the convention for Swtch
so that the proc is passed in R6 and that R6 is clobbered.  This is so
Swtch itself doesn't have to save/restore the proc pointer explicitly.
