PGMHandler.cpp@ 17610

Last change on this file since 17610 was 17517, checked in by vboxsync, 16 years ago
PGM: Fixed PGMVIRTHANDLERTYPE_ALL regression from the other day - it seems like there are a few users of this type after all. Implemented PGMPhysRead support for it. Enforce page-sized-ness of this type just a for PGMPHYSHANDLERTYPE_ALL/MMIO.
