I'm having this same issue with v5.2-rc5 using an older version of gcc
(4.9.2).  If I use a more recent version of gcc (7.3.0) it works fine.

Reverting this patch allows gcc v4.9.2 to build kernel v5.2-rc5 successfully.

You said in this chain that you were reverting this patch in stable
kernels.  Are you going to revert it in tip-of-tree as well?
