Hi Joey, 

I tried Dave's patch to kexec-bzimage64.c on my build of the SuSE
4.12.14-15 kernel.   I ran the same test as I did with your patch: I
verified the early_ioremap.c warnings occurred with a crash triggered
from a kexec boot of the unmodified kernel. Then I applied the patch to
kexec-bzimage64.c, rebuilt, re-ran the test to crash from the kexec'ed
kernel, and verified the warnings are no longer seen.

I'm out of time today, but I will plan to run the same  test tomorrow on
a build of the SuSE 4.4.120-94.17 kernel, on which I had also reported
the original bug.
