-	# This function encrypts eight consecutive ChaCha20 blocks by loading
-	# the state matrix in AVX registers eight times. As we need some
-	# scratch registers, we save the first four registers on the stack. The
-	# algorithm performs each operation on the corresponding word of each
-	# state matrix, hence requires no word shuffling. For final XORing step
-	# we transpose the matrix by interleaving 32-, 64- and then 128-bit
-	# words, which allows us to do XOR in AVX registers. 8/16-bit word
-	# rotation is done with the slightly better performing byte shuffling,
-	# 7/12-bit word rotation uses traditional shift+OR.
