Modified files:
sys/i386/i386 pmap.c
Log:
For physical address regions between 0 and KERNLOAD, allow pmap_mapdev()
to use the direct mapped KVA at KERNBASE to service the request. This also
allows pmap_mapdev() to be used for such addresses very early during the
boot process and might provide some small savings on KVA.
