2015-03-19	arm64/crypto: issue aese/aesmc instructions in pairs	Ard Biesheuvel	1	-6/+6
	This changes the AES core transform implementations to issue aese/aesmc (and aesd/aesimc) in pairs. This enables a micro-architectural optimization in recent Cortex-A5x cores that improves performance by 50-90%. Measured performance in cycles per byte (Cortex-A57): CBC enc CBC dec CTR before 3.64 1.34 1.32 after 1.95 0.85 0.93 Note that this results in a ~5% performance decrease for older cores.
