uapi/linux/stddef.h: Provide __always_inline to userspace headers
Josh Boyer reported that my recent change to uapi/linux/swab.h broke the Qemu build: bc27fb68aaad ("include/uapi/linux/byteorder, swab: force inlining of some byteswap operations") Unfortunately, UAPI headers don't include compiler.h so fixing it there is not enough, add an __always_inline definition to uapi/linux/stddef.h instead. Testcase: "make headers_install" and try to compile this: #include <linux/swab.h> void main() {} Reported-by: Josh Boyer <jwboyer@fedoraproject.org> Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: David Rientjes <rientjes@google.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Thomas Graf <tgraf@suug.ch> Cc: linux-kernel@vger.kernel.org Link: http://lkml.kernel.org/r/1459289697-12875-1-git-send-email-dvlasenk@redhat.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
