Modified Files:
syssrc/sys/arch/powerpc/powerpc: trap_subr.S
Log Message:
Reset segment registers 1-7 upon entry to kernel (via trap or interrupts)
so that the bat spill code won't run into spurious valid user pages and
treat them as kernel pages. Restore segment registers 1-7 upon return to
user mode from either a trap or interrupt. XXX eventually do all 16 SRs
