physical addressing. This has the uncacheable bit as bit 40 as opposed to bit 39. Additionally, we now support (at least superficially) a 44-bit physical address. To deal with superpage access in this scheme, any super page access with either bit 39 or 40 set is sign extended. --HG-- extra : convert_revision : 05ddbcb9a6a92481109a63b261743881953620ab
