http://www.t-es-t.hu/download/mips/md00090c.pdf this is bit 3 of the
config0 word, not bit 2. This should fix virtually indexed caches
(relatively new in the MIPS world, so no current platforms used this
and current code just uses it as an optimization). It was causing
false positives on newer platforms that default to large values for
the kseg0 cache coherency attribute.
