  Optimize pmap_demote_pde() by using the new KPTmap to access a kernel
  page table page instead of creating a temporary mapping to it.

  Set the PG_G bit on the page table entries that implement the KPTmap.

  Locore initializes the unused portions of the NKPT kernel page table
  pages that it allocates to zero.  So, pmap_bootstrap() needn't zero
  the page table entries referenced by CMAP1 and CMAP3.

  Simplify pmap_set_pg().
