Last change on this file since 17616 was 17534, checked in by vboxsync, 16 years ago

PGM: Made PGMPhysRead/Write return VERR_PGM_PHYS_WR_HIT_HANDLER when encountering a handler in R0 and RC. Adjusted PGMPhysReadGCPtr and PGMPhysWriteGCPtr to not waste time on setting A and D bits if they are already set.
