This was an optimization used only by a few xscale platforms. Part of the optimization was to create a direct map for all physical pages, and that resulted in making multiple mappings of pages in a way that bypassed the logic in pmap.c to handle VIVT cache aliasing. It also just generally made the code more complex and hard to maintain for all SoCs. Reviewed by: cognet
