Just a friendly reminder. It will be nice to increase the minimum GCC version to GCC 5.x globally. Now, the version check has been moved to scripts/cc-version.sh, which is invoked from Kconfig. If you decide to do this, please update 'gcc_min_version' in that file. I'd like to suggest GCC 5.2 instead of 5.1 so that we can drop the following line from arch/powerpc/Kconfig. if GCC_VERSION >= 50200 # plugin support on gcc <= 5.1 is buggy on PPC > > Note that banning 4.9 for arm64 and banning it in general should be > > two different changes in any case, as the former will need to be > > backported to -stable kernels as well. > > Yes.
