pk d0b1ee0833 * Optimize pmap_{zero,copy}_page4m() a bit by pre-computing the PTE addresses

of the reserved KVAs (vpage[]) used by these routines. This avoids the
  context switching in there.

* In pmap_redzone(), remove the first kernel address (at KERNBASE) from
  the kernel maps instead of just turning off the PTE `valid' bits.
  The latter doesn't create a "red zone" at all, but causes the VM to
  allocate a new page if the red zone is touched.
