SVN rev 214739 on 2010-11-03 15:15:48Z by nwhitehorn
Clean up the user segment handling code a little more. Now that
set_user_sr() itself caches the user segment VSID, there is no need for
cpu_switch() to do it again. This change also unifies the 32 and 64-bit
code paths for kernel faults on user pages and remaps the user SLB slot
on 64-bit systems when taking a syscall to avoid some unnecessary segment
exception traps.
