Alan Cox 0c645b7267 In general, the kernel virtual address of the pml4 page table page that is
stored in the pmap is from the direct map region.  The two exceptions have
been the kernel pmap and the swapper's pmap.  These pmaps have used a
kernel virtual address established by pmap_bootstrap() for their shared
pml4 page table page.  However, there is no reason not to use the direct
map for these pmaps as well.
