crypto: sun8i-ss - use crypto_shash_tfm_digest() in sun8i_ss_hashkey() Simplify sun8i_ss_hashkey() by using crypto_shash_tfm_digest() instead of an alloc+init+update+final sequence. This should also improve performance. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: sun8i-ss - Remove GFP_DMA and add DMA alignment padding GFP_DMA does not guarantee that the returned memory is aligned for DMA. In fact for sun8i-ss it is superfluous and can be removed. However, kmalloc may start returning DMA-unaligned memory in future so fix this by adding the alignment by hand.

crypto: sha - split sha.h into sha1.h and sha2.h Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.
