 Log Message:
 Pull up following revision(s) (requested by skrll in ticket #1068):
 	sys/arch/mips/include/pmap.h: revision 1.63
 	sys/arch/mips/mips/pmap.c: revision 1.214
 	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 qube 2
 PR/48628 - cobalt and hpcmips ports are dead
