Insufficient bounding of "REP MOVS" to MMIO emulated inside the hypervisor

ISSUE DESCRIPTION Acceleration support for the "REP MOVS" instruction, when the first iteration accesses memory mapped I/O emulated internally in the hypervisor, incorrectly assumes that the whole range accessed is handled by the same hypervisor sub-component. IMPACT A buggy or malicious HVM gues...
