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.
