I see multiple instances of:

This is due to commit 9b2d4e06d7f1 ("powerpc/64s: Add support for a store
forwarding barrier at kernel entry/exit"), which is part of a large patch
series and can not easily be reverted.

Guess I'll stop doing ppc:allmodconfig builds in v4.4.y ?

Michael, I thought this patch series was supposed to fix ppc issues, not
add to them :)

Any ideas on what to do here?

What exact code do you build?

$ make ARCH=powerpc CROSS_COMPILE=powerpc64-linux- allmodconfig
$ powerpc64-linux-gcc --version
powerpc64-linux-gcc (GCC) 8.3.0
