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