        src/sys/arch/sparc64/include: userret.h
        src/sys/arch/sparc64/sparc64: trap.c

Log Message:
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.
