[1/1] powerpc/64s: Fix allnoconfig build since uaccess flush
      https://git.kernel.org/powerpc/c/b6b79dd53082db11070b4368d85dd6699ff0b063

We also needed a similar fix for stable, which has also been applied.

I guess I should build some sort of build process that tests a whole
range of configs. I did test a few but clearly not enough. Is there a
known list that I should be using? Something from kisskb?

It's basically unsolvable in general. I guess allnoconfig is a good one
to build, although by default that gets you a 32-bit config.

I'll send a patch to add ppc64le_allnoconfig.

cheers
