David Greenman d23d07ef95 Merged in post-1.1.5 work done by myself and John Dyson. This includes:
me:
1) TLB flush optimization that effectively eliminates half of all of the
   TLB flushes. This works by only flushing the TLB when a page is "present"
   in memory (i.e. the valid bit is set in the page table entry). See section
   5.3.5 of the Intel 386 Programmer's Reference Manual.
2) The handling of "CMAP" has been improved to catch attempts at multiple
   simultaneous use.

John:
1) Added pmap_qenter/pmap_qremove functions for fast mapping of pages into
   the kernel. This is for future optimizations and support for the upcoming
   merged VM/buffer cache.
