	---

	This patch adds AVX/AVX2/AESNI/GFNI accelerated ARIA block cipher
	implementations for libgcrypt. This implementation is based on work
	by Taehee Yoo, with following notable changes:
	 - Integration to libgcrypt, use of 'aes-common-amd64.h'.
	 - Use 'vmovddup' for loading GFNI constants.
	 - Use round loop instead of unrolling for smaller code size and
	   increased performance.
	 - Use stack for temporary storage instead of external buffers.
	 - Use merge ECB encryption/decryption to single function.
	 - Add 1 to 15 blocks support for AVX ECB functions.
	 - Add byte-addition fast path for CTR.
