Can't - we just upped min gcc version to 4.8: 5429ef62bcf3 ("compiler/gcc: Raise minimum GCC version for kernel builds to 4.8") I mean we could but everytime we do that, it is all a big bikeshedding discussion. Even though almost everyone is using gcc9 or so to build... -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
