[kbuild test robot]

Hi Anton,

[auto build test ERROR on powerpc/next]
[also build test ERROR on next-20151208]
[cannot apply to v4.4-rc4]

url:    https://github.com/0day-ci/linux/commits/Anton-Blanchard/powerpc-Call-restore_sprs-on-initial-context-switch/20151209-123550
base:   https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next
config: powerpc-allnoconfig (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
