CVS commit: src/sys/arch/mips/mips

["Simon Burge" <simonb%netbsd.org@localhost>]

Module Name:    src
Committed By:   simonb
Date:           Sun Jun 28 13:33:06 UTC 2020

Modified Files:
        src/sys/arch/mips/mips: mips_machdep.c

Log Message:
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).
