Crypto now fails on arm allmodconfig:

[many more similar scalar errors deleted]

The 2.2.3 warning was there in the past, but it wasn't fatal. I'm using
an older binutils 2.22 from the kernel.org crosstool stuff.

Seems sfr's builds get the same issue:

A mindless "git bisect run" comes up with:

cc477bf645736739e69d31fdf715281ef0dd5f9b is the first bad commit
commit cc477bf645736739e69d31fdf715281ef0dd5f9b
Author: Ard Biesheuvel <ard.biesheuvel@linaro.org>
Date: Wed Jan 11 16:41:54 2017 +0000

crypto: arm/aes - replace bit-sliced OpenSSL NEON code

Maybe binnutils 2.22 is finally too old?

Paul.
