I had to revert the following commits to get this kernel to build
(otherwise I got macro expansion errors, using RHEL7
gcc-4.8.5-28.el7.x86_64):
beb7eb2 kernelh-skip-single-eval-logic-on-literals-in-min-max-v3
19ff7e5 kernelh-skip-single-eval-logic-on-literals-in-min-max-v2
c7c133f kernel.h: skip single-eval logic on literals in min()/max()
(it wasn't until I reverted commit c7c133f that the kernel build worked)
Here is a snippet of the errors if commit c7c133f was applied:
