Hi Wang,

[auto build test ERROR on arm64/for-next/core]
[also build test ERROR on v4.4-rc6 next-20151223]

url:    https://github.com/0day-ci/linux/commits/Wang-Nan/arm64-Store-breakpoint-single-step-state-into-pstate/20151223-165432
base:   https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux for-next/core
config: arm64-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
