crypto: aesni-intel - Add AES-NI accelerated CTR mode
To take advantage of the hardware pipeline implementation of AES-NI
instructions. CTR mode cryption is implemented in ASM to schedule
multiple AES-NI instructions one after another. This way, some latency
of AES-NI instruction can be eliminated.
Performance testing based on dm-crypt should 50% reduction of
ecryption/decryption time.
