The patch looks good, but when we add the feature names to
cpuid_7_0_ecx_feature_name, QEMU will consider them as
migratable, but they are truly migratable only after we add the
ext_save_areas entry.
We can fix this by moving cpuid_7_0_ecx_feature_name to patch 2/3
(or to a separate patch, to be applied after 2/3).
