This makes an already long name longer, and somewhat incomprehensible. To avoid this, rename the base macro to X86_MATCH_CPU. The macro name doesn't need to explicitly tell everything that it matches. The arguments to the macro already hints that. For consistency, use this base macro to define X86_MATCH_VFM and friends.
