I disagree.  The minimum version of gcc required to build the kernel
is 4.6, so the comment about older versions of gcc is irrelevant and
should be removed.

Nathan's -Rpass warnings are warning that vectorization was not

Surely we wouldn't disable NEON opts for XOR because 1 of 4 was not
vectorized?
