As +// result 64-bit NEON version of SHA256 was added to provide best +// all-round performance. For example it executes ~30% faster on X-Gene +// and Mongoose. [For reference, NEON version of SHA512 is bound to +// deliver much less improvement, likely *negative* on Cortex-A5x. +// Which is why NEON support is limited to SHA256.] + +#ifndef __KERNEL__ +#
