crypto: arm64/sha512-ce - clean up backwards function names In the Linux kernel, a function whose name has two leading underscores is conventionally called by the same-named function without leading underscores -- not the other way around. __sha512_ce_transform() and __sha512_block_data_order() got this backwards. Fix this, albeit without changing "sha512_block_data_order" in the perlasm since that is OpenSSL code. No change in behavior.

crypto: arm64/sha512-ce - simplify NEON yield Instead of calling into kernel_neon_end() and kernel_neon_begin() (and potentially into schedule()) from the assembler code when running in task mode and a reschedule is pending, perform only the preempt count check in assembler, but simply return early in this case, and let the C code deal with the consequences. This reverts commit 6caf7adc5e458f77f550b6c6ca8effa152d61b4a. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: arm64/sha - add missing module aliases The accelerated, instruction based implementations of SHA1, SHA2 and SHA3 are autoloaded based on CPU capabilities, given that the code is modest in size, and widely used, which means that resolving the algo name, loading all compatible modules and picking the one with the highest priority is taken to be suboptimal. However, if these algorithms are requested before this CPU feature based matching and autoloading occurs, these modules are not even considered, and we end up with suboptimal performance. So add the missing module aliases for the various SHA implementations.

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.

crypto: shash - remove useless setting of type flags Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH. But this is redundant with the C structure type ('struct shash_alg'), and crypto_register_shash() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the shash algorithms. This patch shouldn't change any actual behavior.
