        sys/arch/mips/mips/mips_machdep.c: revision 1.294

Fix mm_md_kernacc() for 64 bit kernels (including n32):
 - FAULT for any physical address less than start of cached XKPHY address.
 - Pass any remaining physical address less then end of RAM.
 - Pass any remaining physical address within the KEGS0 kernel address range.

Ignore all remaining addresses and fall back to uvm_kernacc() for checking
virtual address ranges.

Fixes pmap(1) (and probably other kmem grovellers).
