nwhitehorn 4eb3d8da4b Reduce KVA pressure on OEA64 systems running in bridge mode by mapping ... UMA segments at their physical addresses instead of into KVA. This emulates the direct mapping behavior of OEA32 in an ad-hoc way. To make this work properly required sharing the entire kernel PMAP with Open Firmware, so ofw_pmap is transformed into a stub on 64-bit CPUs. Also implement some more tweaks to get more mileage out of our limited amount of KVA, principally by extending KVA into segment 16 until the beginning of the first OFW mapping.
