John Dyson 95461b450d 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.		1998-02-05 03:32:49 +00:00
