In addition to usual CPUID bits, some CPU features started to be reported in IA32_ARCH_CAPABILITIES MSR. This series adds support for such CPU features.
However, the last patch which actually adds definitions for some MSR features to the cpu_map should not be pushed yet as the QEMU interface for MSR features is not complete yet. If a domain with some MSR features enabled would be started, all of them would be marked as disabled in the live domain configuration (even though they were actually enabled by QEMU) and they would disappear during migration.
