At this time we only distinguish between UC and WB memory so that we can map the page to either a region 6 address (for UC) or a region 7 address (for WB). This change is only now possible, because previously we would map regions 6 and 7 with 256MB translations and on top of that had the kernel mapped in region 7 using a wired translation. The introduction of the PBVM moved the kernel into its own region and freed up region 7 and allowed us to revert to standard page-sized translations. This commit inroduces pmap_page_to_va() that respects the attribute.
