Hi Mikko,

[auto build test ERROR on linus/master]
[also build test ERROR on v4.8-rc3 next-20160822]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
[Suggest to use git(>=2.9.0) format-patch --base=<commit> (or --base=auto for convenience) to record what (public, well-known) commit your patch series was built on]
[Check https://git-scm.com/docs/git-format-patch for more information]

config: x86_64-randconfig-s2-08230509 (attached as .config)
compiler: gcc-4.4 (Debian 4.4.7-8) 4.4.7
reproduce:
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: the linux-review/Mikko-Rapeli/Userspace-compile-test-and-fixes-for-exported-uapi-header-files/20160823-034928 HEAD ab90ab906304d4f306e440f4dbfa334720093b4f builds fine.
      It only hurts bisectibility.
