Added new lock system for the two virtual pages used in temporary mappings.
...
Allows pmap_zero_page() and pmap_copy_page() to be re-entrant.

Implement code to dynamically size the number of page tables based on available
...
RAM at boot.
Also did some cleanup of unused functions, updated several comments, and
removed unecessary 'XXX's.

Implement pmap_pa_exists() so that /dev/mem works.
...
This was the reason ps (kvm_getargs) did not work.

Physical page status functions pmap_clear_reference()
...
and pmap_clear_modify() weren't testing if the page whose status was being
changed was being managed. This caused kernel panics with X11.

Add pmap_bootstrap_setprom() with sets the PROM level-A tables to
...
allow the PROM monitor to see mappings in kernel space. This also
fixes a problem with exiting to the monitor with the stack pointer
set to some place in kernel space. Also fix NUM_KERN_PTES, and
change get_pte() so it works on any virtual address.

Took switch statement out of main loop in pmap_protect() and explained more

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.
Now pmap_activate() is called only by locore (and that call is
done only if PMAP_DEBUG is defined). Other minor clean-up...

Adapt to rename of pcb_mmuctx to pcb_mmucrp, and corrected

prototype of loadcrp(), which kills some bogus type casts.
