Subject: [PATCH v3 0/2] xor-neon: Remove GCC warn & pragmas

Dear all,

This is v3 of the patch series started at
id:20201106051436.2384842-1-adrian.ratiu@...labora.com

This series does not address the Clang -ftree-vectorize not
working bug 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-20201112 using GCC 10.2.0 and Clang 10.0.1.

Kind regards,
Adrian
