Log:
  Correct the CONFIG0_VI value. According to
  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.
