Eric Biggers 99680c5e91 crypto: arm - convert to use crypto_simd_usable()
Replace all calls to may_use_simd() in the arm crypto code with
crypto_simd_usable(), in order to allow testing the no-SIMD code paths.

Arnd Bergmann 3723c63247 treewide: convert ISO_8859-1 text comments to utf-8
Almost all files in the kernel are either plain text or UTF-8 encoded.  A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.

This converts them all to UTF-8 for consistency.

Eric Biggers 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.

Ard Biesheuvel b59e2ae369 crypto: arm/sha256 - move SHA-224/256 ASM/NEON implementation to base layer
This removes all the boilerplate from the existing implementation,
and replaces it with calls into the base layer.

Sami Tolvanen f2f770d74a crypto: arm/sha256 - Add optimized SHA-256/224
Add Andy Polyakov's optimized assembly and NEON implementations for
SHA-256/224.

The sha256-armv4.pl script for generating the assembly code is from
OpenSSL commit 51f8d095562f36cdaa6893597b5c609e943b0565.

Compared to sha256-generic these implementations have the following
tcrypt speed improvements on Motorola Nexus 6 (Snapdragon 805):

Where bs refers to block size and b/u to bytes per update.
