        src/sys/arch/sparc64/include [netbsd-5-0]: userret.h
        src/sys/arch/sparc64/sparc64 [netbsd-5-0]: trap.c

Log Message:
Pull up the following revisions(s) (requested by nakayama in ticket #1103):
        sys/arch/sparc64/include/userret.h:     revision 1.9
        sys/arch/sparc64/sparc64/trap.c:        revision 1.158

Merge want_ast check in userret() into trap handler, and repeat preempt()
call while want_resched is true.  While there remove unnecessary #if 1. This
should fix a performance degradation of disk I/O on heavy load.
