+ [BZ #14648]
+ * sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features):
+ Set bit_FMA_Usable if FMA is supported.
+ * sysdeps/x86_64/multiarch/init-arch.h (bit_FMA_Usable): New
+ macro.
+ (bit_FMA4_Usable): Updated.
+ (index_FMA_Usable): New macro.
+ (CPUID_FMA): Likewise
+ (HAS_FMA): Defined with bit_FMA_Usable.
