  SVN rev 182878 on 2008-09-08 21:24:25Z by marius
  
  For cheetah-class CPUs ensure that the dt512_0 is set to hold 8k pages
  for all three contexts and configure the dt512_1 to hold 4MB pages for
  them (e.g. for direct mappings).
  This might allow for additional optimization by using the faulting
  page sizes provided by AA_DMMU_TAG_ACCESS_EXT for bypassing the page
  size walker for the dt512 in the superpage support code.
