Update of /a/cvsroot/src/sys/arch/alpha/alpha
In directory pain.lcs.mit.edu:/a/tmp/cvs-serv3837/alpha

Modified Files:
	locore.s machdep.c process_machdep.c trap.c vm_machdep.c 
Log Message:
don't save and set the USP at every trap entry and exit.  It's
unnecessary, and given that there's no reason to waste time and
add complexity in trap handlers.  This means that code which sets and
uses the USP has to be a bit more careful, but that doesn't happen much.
