  • To reduce the number of copies of boilerplate code throughout
    the tree, this patch implements generic glue for the SHA-512
    algorithm. This allows a specific arch or hardware implementation
    to only implement the special handling that it needs.

    The users need to supply an implementation of

    void (sha512_block_fn)(struct sha512_state *sst, u8 const *src, int blocks)

    and pass it to the SHA-512 base functions. For easy casting between the
    prototype above and existing block functions that take a 'u64 state[]'
    as their first argument, the 'state' member of struct sha512_state is
    moved to the base of the struct.
