An internal table, maintained by the CPU and/or hypervisor, and if in physical addresses then in a region which is only accessible by the hypervisor. The table is not accessible by the kernel at all via loads or stores. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
