grehan d0fe48c3c0 Major overhaul of common trap code 
- remove unused 601 and tlb exception code
 - remove interrupt-time PTE spill code. The pmap code
   will now take care of pinning kernel PTEs, and there
   are no longer issues about physical mapping of PTE
   data structures
 - All segment registers are switched on kernel entry/exit,
   allowing the kernel to have more virtual space and for
   user virtual space to extend to 4G.
 - The temporary register save area has been shifted from
   unused exception vector space to the per-cpu data area.
   This allows interrupts to be delivered to multiple CPUs
 - ISI traps no longer spill to BAT tables. It is assumed
   that all of kernel instruction memory is pinned.
 - shift from 'ldmw/stmw' instructions to individual register
   loads/stores when saving context. All PPC manuals indicate
   this should be much faster.
 - use '%r' for register names throughout.

TODO: need to test if DSI traps were the result of kernel stack
guard-page hits.
