Log Message:
Pull up following revision(s) (requested by skrll in ticket #1068):
        sys/arch/mips/mips/pmap.c: revision 1.214
        sys/arch/mips/include/pmap.h: revision 1.63
        sys/arch/mips/mips/pmap_segtab.c: revision 1.8
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 qube2
PR/48628 - cobalt and hpcmips ports are dead
