+	* gcm.c (gcm_rightshift): Complete rewrite, to use word rather
+	than byte operations. Improves gmac performance from 830 cycles /
+	byte to (still poor) 268 cycles per byte on intel x86_64.
+	(gcm_gf_mul): Rewrote. Still uses the bitwise algorithm from the
+	specification, but with separate byte and bit loops. Improves gmac
+	performance a bit further, to 227 cycles/byte.
