Subject: [PATCH v4 0/2] xor-neon: Remove GCC warn & pragmas

Dear all,

In v4 a Clang-specific vectorization warning was added at
Arnd suggestion.

This series does not address the Clang vectorize not working
bug itself which is a known pre-existing issued documented
at [1] [2] [3]. Clang vectorization needs to be investigated
in more deepth and fixed separately. The purpouse of this is
to only fix some low-hanging-fruit GCC related isues.

Tested on next-20210118 using GCC 10.2.0 and Clang 10.0.1.

Kind regards,
Adrian
