e52b7023cd crypto: arm64 - convert to use crypto_simd_usable()
Replace all calls to may_use_simd() in the arm64 crypto code with
crypto_simd_usable(), in order to allow testing the no-SIMD code paths.

e50944e219 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.

0771f3234d crypto: arm64/sha1-ce - add non-SIMD generic fallback
The arm64 kernel will shortly disallow nested kernel mode NEON, so
add a fallback to scalar C code that can be invoked in that case.

f4857f4c2e crypto: arm64/sha - avoid non-standard inline asm tricks
Replace the inline asm which exports struct offsets as ELF symbols
with proper const variables exposing the same values. This works
around an issue with Clang which does not interpret the "i" (or "I")
constraints in the same way as GCC.

bf7883ebcb crypto: arm64/sha1-ce - prevent asm code finalization in final() path
Ensure that the asm code finalization path is not triggered when
invoked via final(), since it already takes care of that itself.
