The fallouts I found are on the way to mainline or are already
in mainline:

fbdev: https://git.kernel.org/tomba/c/206fc20598157ce15597822cf01b94377e30075b
mips:  https://git.kernel.org/torvalds/c/f4d3d504198d464e406171cfa554a59bd4773d79

There was also a hickup on alpha. The patch is on the way. 

Here is the list of archs and config I tried out. First run was with the
config listed, followed by a allyesconfig and allmodconfig build. 

#    name      ARCH     CROSS_COMPILE        config
