SubjectRe: [PATCH] MIPS: Fix minimum alignment requirement of IRQ stack
Hi Matt,

[auto build test WARNING on linus/master]
[also build test WARNING on v4.12 next-20170707]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Matt-Redfearn/MIPS-Fix-minimum-alignment-requirement-of-IRQ-stack/20170709-054925
config: mips-fuloong2e_defconfig (attached as .config)
compiler: mips64el-linux-gnuabi64-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=mips
