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
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.

c0b46da054 Use IOMMU_PAGE_SIZE instead of NBPG, since theoretically the IOMMU page size 
is different than the CPU page size.

290f55615a Took switch statement out of main loop in pmap_protect() and explained more 
of the rationale behind it.

202a9fe423 Added some more comments and disabled removal of DVMA alias mapping from 
kernel space in dvma_mapout() as it may cause problems with the current
pmap_remove().

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

c4fa121f14 Reinstate call to pmap_activate() for now, because it is helpful 
for debugging the pmap code.  The in-line version of the same is
still here and will be used if PMAP_DEBUG is not defined.

165a7a3eeb Put all the name/value pairs in an initialized array of structures

This program can still be run the old way for verification.
