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 from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
