alc 12ebfa7cd9 Eliminate pmap_growkernel()'s dependence on create_pagetables() preallocating
page directory pages from VM_MIN_KERNEL_ADDRESS through the end of the
kernel's bss.  Specifically, the dependence was in pmap_growkernel()'s one-
time initialization of kernel_vm_end, not in its main body.  (I could not,
however, resist the urge to optimize the main body.)

Reduce the number of preallocated page directory pages to just those needed
to support NKPT page table pages.  (In fact, this allows me to revert a
couple of my earlier changes to create_pagetables().)
