SubjectRe: [PATCH v3 4/7] alpha: Add support for memset16
Hi Matthew,

[auto build test ERROR on linus/master]
[also build test ERROR on v4.11-rc3 next-20170324]
[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/Matthew-Wilcox/Add-memsetN-functions/20170326-140108
config: alpha-allyesconfig (attached as .config)

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