SVN rev 190055 on 2009-03-19 14:15:11Z by marius
MFC: r182878
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.
Submitted by: nwhitehorn (initial patch)
