However, we are going to have much bigger problem starting with 4.18-rc1 as there even running "make oldconfig" with ARCH set may result in different .config than running it on the actual architecture.
Oh that's messy... How can it happen?
There is a more detailed e-mail about this in SUSE kernel list (subject "Kconfig changes in v4.18-rc1"). The short story is that Kconfig now writes also info about gcc version and capabilities into .config so that using different gcc when updating configs than one used later for build may be a problem. And I also found than updating ppc64le/default config (master branch) with gcc 8.1.1 on x86_64 (with ARCH=powerpc) - which is what run_oldconfig.sh does - results in different .config than when I do the same on ppc64le machine. I'm going to do some research if we can work around this without having to use at least a crosscompiler.
