Log message:
Changes to turn on protection ID checking. Also some cleanup.

entry.S:
Remove old code. Remove support for uncached pages on PA2.0
processors. Properly initialize protection id for translations.

traps.c:
Fix bug where kernel would die if user touched kernel address
space. Added support for traps 7 and 27 (I and D protection
faults) since they can now be generated.

processor.h:
Remove silly nullify trick. Use psw definition that contains
P bit. Remove pg_tables field from thread structure.

psw.h:
Remove USER_INIT_PSW. Add PSW_P to USER_PSW and KERNEL_PSW.

mmu_context.h:
Load protection Id register (cr8) in switch_mm(). Get rid
of usage of pg_tables field, since it is not used anywhere
else.

pgalloc.h:
Load corresponding protection Id register if space is
changed in flush_tlb_mm().
