Change 28269 by marcel at marcel_nfs on 2003/04/05 15:17:36

	Adopt the new cpu_switch() where the old and new threads are
	being passed in. We will probably end up with a C version for
	cpu_switch() that will call swapctx(), where swapctx() will
	take pointers to PCBs. In combination with savectx() and
	restorectx() this mirrors the system calls we have and limits
	the amount of tedious assembly that has to be written and
	maintained.
