Modified Files:
src/sys/arch/mips/include: pmap.h
src/sys/arch/mips/mips: pmap.c pmap_segtab.c
Log Message:
Deal with incompatible cache aliases. Specifically,
- always flush an ephemeral page on unmap
- track unmanaged mappings (mappings entered via pmap_kenter_pa) for
aliases where required and handle appropriately (via pmap_enter_pv)
Hopefully this (finally) addresses the instability reported in the
following PRs:
PR/44900 - R5000/Rm5200 mips ports are broken
PR/46890 - upcoming NetBSD 6.0 release is very unstable / unusable on cobalt
qube 2
PR/48628 - cobalt and hpcmips ports are dead
