  Log:
  1)	Start using a cleaner and more consistant page allocator instead
  	of the various ad-hoc schemes.
  2)	When bringing in UPAGES, the pmap code needs to do another vm_page_lookup.
  3)	When appropriate, set the PG_A or PG_M bits a-priori to both avoid some
  	processor errata, and to minimize redundant processor updating of page
  	tables.
  4)	Modify pmap_protect so that it can only remove permissions (as it
  	originally supported.)  The additional capability is not needed.
  5)	Streamline read-only to read-write page mappings.
  6)	For pmap_copy_page, don't enable write mapping for source page.
  7)	Correct and clean-up pmap_incore.
  8)	Cluster initial kern_exec pagin.
  9)	Removal of some minor lint from kern_malloc.
  10)	Correct some ioopt code.
  11)	Remove some dead code from the MI swapout routine.
  12)	Correct vm_object_deallocate (to remove backing_object ref.)
  13)	Fix dead object handling, that had problems under heavy memory load.
  14)	Add minor vm_page_lookup improvements.
  15)	Some pages are not in objects, and make sure that the vm_page.c can
  	properly support such pages.
  16)	Add some more page deficit handling.
  17)	Some minor code readability improvements.
