  Log:
  Eliminated many redundant vm_map_lookup operations for vm_mmap.
  Speed up for vfs_bio -- addition of a routine bqrelse to greatly diminish
  	overhead for merged cache.
  Efficiency improvement for vfs_cluster.  It used to do alot of redundant
  	calls to cluster_rbuild.
  Correct the ordering for vrele of .text and release of credentials.
  Use the selective tlb update for 486/586/P6.
  Numerous fixes to the size of objects allocated for files.  Additionally,
  	fixes in the various pagers.
  Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs.
  Fixes in the swap pager for exhausted resources.  The pageout code
  	will not as readily thrash.
  Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into
  	page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE),
  	thereby improving efficiency of several routines.
  Eliminate even more unnecessary vm_page_protect operations.
  Significantly speed up process forks.
  Make vm_object_page_clean more efficient, thereby eliminating the pause
  	that happens every 30seconds.
  Make sequential clustered writes B_ASYNC instead of B_DELWRI even in the
  	case of filesystems mounted async.
  Fix a panic with busy pages when write clustering is done for non-VMIO
  	buffers.
