Hi Qais,

[auto build test ERROR on tip/irq/core]
[also build test ERROR on v4.4-rc4 next-20151208]

url: https://github.com/0day-ci/linux/commits/Qais-Yousef/Implement-generic-IPI-support-mechanism/20151208-212743
config: mips-malta_defconfig (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
