Re: [PATCH 13/20] powerpc: Use generic compat_siginfo_t

[kbuild test robot]

Hi Amanieu,

[auto build test ERROR on arm64/for-next/core -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url:    https://github.com/0day-ci/linux/commits/Amanieu-d-Antras/Fix-handling-of-compat_siginfo_t/20151015-051137
config: powerpc-defconfig (attached as .config)
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=powerpc 

Note: the linux-review/Amanieu-d-Antras/Fix-handling-of-compat_siginfo_t/20151015-051137 HEAD 041b7d538bec8eec85a60b4a808bbe3959fcd8c3 builds fine.
      It only hurts bisectibility.
