[PATCH net-next v6 10/23] zinc: Poly1305 x86_64 implementation

[Jason A. Donenfeld]

This provides AVX, AVX-2, and AVX-512F implementations for Poly1305.
The AVX-512F implementation is disabled on Skylake, due to throttling.
These come from Andy Polyakov's implementation, with the following
modifications from Samuel Neves:

  - Some cosmetic changes, like renaming labels to .Lname, constants,
    and other Linux conventions.

  - CPU feature checking is done in C by the glue code, so that has been
    removed from the assembly.

  - poly1305_blocks_avx512 jumped to the middle of the poly1305_blocks_avx2
    for the final blocks. To appease objtool, the relevant tail avx2 code
    was duplicated for the avx512 function.

  - The original uses %rbp as a scratch register. However, the kernel
    expects %rbp to be a valid frame pointer at any given time in order
    to do proper unwinding. Thus we need to alter the code in order to
    preserve it. The most straightforward manner in which this was
    accomplished was by replacing $d3, formerly %r10, by %rdi, and
    replacing %rbp by %r10. Because %rdi, a pointer to the context
    structure, does not change and is not used by poly1305_iteration,
    it is safe to use it here, and the overhead of saving and restoring
    it should be minimal.

  - The original hardcodes returns as .byte 0xf3,0xc3, aka "rep ret".
    We replace this by "ret". "rep ret" was meant to help with AMD K8
    chips, cf. http://repzret.org/p/repzret. It makes no sense to
    continue to use this kludge for code that won't even run on ancient
    AMD chips.

While this is CRYPTOGAMS code, the originating code for this happens to
be the same as OpenSSL's commit 4dfe4310c31c4483705991d9a798ce9be1ed1c68
