Hi Mathieu,

[auto build test ERROR on arm/for-next]
[also build test ERROR on v4.5-rc5 next-20160223]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]

wget -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=arm

All errors (new ones prefixed by >>):
