Hi Suzuki,
[auto build test ERROR on v4.3-rc4 -- if it's inappropriate base, please ignore]
config: arm64-alldefconfig (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=arm64
Note: the linux-review/Suzuki-K-Poulose/arm64-Consolidate-CPU-feature-handling HEAD bfdef3a10032e84cc7ae186a058443219f110679 builds fine. It only hurts bisectibility.
All errors (new ones prefixed by >>):
