x86/boot: Disable Clang warnings about GNU extensions
The kernel makes use of several GCC extensions, disable Clang warnings about that in the boot code, as we already do for the rest of the kernel. This suppresses the following warning when building with clang: ./include/linux/cgroup-defs.h:391:16: warning: field 'cgrp' with variable sized type 'struct cgroup' not at the end of a struct or class is a GNU extension [-Wgnu-variable-sized-type-not-at-end] struct cgroup cgrp; Reported-by: Nick Desaulniers <nick.desaulniers@gmail.com> Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Acked-by: Thomas Gleixner <tglx@linutronix.de> Cc: Douglas Anderson <dianders@chromium.org> Cc: Guenter Roeck <groeck@chromium.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20171030194351.122090-1-mka@chromium.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
