Log:
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.
Submitted by: nwhitehorn (initial patch)
