Pull up following revision(s) (requested by skrll in ticket #22):
        sys/arch/mips/mips/mips_machdep.c: revision 1.278
        sys/arch/mips/mips/pmap_machdep.c: revision 1.21
Always use XKPHYS for pool pages on _LP64; otherwise use KSEG0
--
Maintain the split of physical memory into the defined freelists, but
only force pool pages to VM_FREELIST_FIRST512M for non _LP64
