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.
