The clang warning 'address-of-packed-member' is disabled for the general kernel code, also disable it for the x86 boot code. This suppresses a bunch of warnings like this when building with clang: ./arch/x86/include/asm/processor.h:535:30: warning: taking address of packed member 'sp0' of class or structure 'x86_hw_tss' may result in an unaligned pointer value [-Waddress-of-packed-member] return this_cpu_read_stable(cpu_tss.x86_tss.sp0); ^~~~~~~~~~~~~~~~~~~ ./arch/x86/include/asm/percpu.h:391:59: note: expanded from macro 'this_cpu_read_stable' #define this_cpu_read_stable(var) percpu_stable_op("mov", var) ^~~ ./arch/x86/include/asm/percpu.h:228:16: note: expanded from macro 'percpu_stable_op' : "p" (&(var))); ^~~ Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Cc: Doug Anderson <dianders@chromium.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/20170725215053.135586-1-mka@chromium.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
