Marcel Moolenaar 7df304f3e0 Stop linking against a direct-mapped virtual address and instead
use the PBVM. This eliminates the implied hardcoding of the
physical address at which the kernel needs to be loaded. Using the
PBVM makes it possible to load the kernel irrespective of the
physical memory organization and allows us to replicate kernel text
on NUMA machines.

While here, reduce the direct-mapped page size to the kernel's
page size so that we can support memory attributes better.
