Re: [PATCH 4/5] kernel/cpu.c: eliminate cpu_*_mask

[kbuild test robot]

Hi Rasmus,

[auto build test results on v4.3-rc2 -- if it's inappropriate base, please ignore]

config: powerpc-allyesconfig (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
  git checkout c14fd9e74ebf7540e312ff440343f9843917ec66
  # save the attached .config to linux build tree
  make.cross ARCH=powerpc
