Jake Burkholder 6e5f166d2c Great pmap rewrite to use a much simpler one level tsb of ttes, instead ... of sttes. Also removes many differences between this and the other pmaps. Reserve the kva space used by the openfirmware translations. Use physical addresses directly in pmap_zero_page and pmap_copy_page, now that we have the cache line shooting support. Add code to track the virtual cachability of mapped pages. The dmmu requires that multiple mappings of the same phsyical address have the save virtual address bits up to a colour boundary. Violating this requires all mappings to be mapped uncacheable. We do not yet handle the case of a badly aliased mapping becoming cachable again. Many crucial bug fixes from: tmm		2001-12-29 08:11:02 +00:00
