Alan Cox 1eaff126fa Temporarily disable the use of 1GB page mappings by the direct map. There ... are currently two problems with the use of 1GB page mappings by the direct map. First, at least one device driver uses pmap_extract() rather than DMAP_TO_PHYS() to translate a direct map address to a physical address. Unfortunately, neither pmap_extract() nor pmap_kextract() yet support 1GB page mappings. Second, pmap_bootstrap() needs to interrogate the MTRRs to ensure that a 1GB page mapping doesn't span two MTRRs of different types.
