a4e5a18b63 Add pmap_bootstrap_setprom() with sets the PROM level-A tables to 
allow the PROM monitor to see mappings in kernel space.  This also

set to some place in kernel space.  Also fix NUM_KERN_PTES, and
change get_pte() so it works on any virtual address.

7190ad9936 Fix a major bug in pmap_remove_kernel() that causd the removal of 
one page too many (worse, it unmapped our stack page... Ouch!)
Also, use loadcrp() and such instead of calling pmap_activate
in various places so we have more control over TLB flush.

done only if PMAP_DEBUG is defined).  Other minor clean-up...
