Subject: linux-next: build failure in Linus' tree

Hi all,

Building Linus' tree, today's linux-next build (sparc64 defconfig)
failed like this:

<stdin>:1515:2: error: #warning syscall clone3 not implemented [-Werror=cpp]
cc1: all warnings being treated as errors

Caused by commit

  3fe617ccafd6 ("Enable '-Werror' by default for all kernel builds")

I have added this patch for today (I guess I could have used
-Wno-error=cpp).

Subject: [PATCH] don't make the syscall checking produced errors from warnings
