So the alignment is just L1_CACHE_BYTES, which is a constant. Why don't you just put that into the struct and then simply align the whole struct? To get the aligned ctx, you can make a wrapper around ahash_request_ctx that does the aligning for you. Have a look at drivers/crypto/padlock-aes.c which does something similar for the tfm ctx.
