SubjectRe: [PATCH v3 3/7] x86: Implement memset16, memset32 & memset64
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: i386-randconfig-x077-201713 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
# save the attached .config to linux build tree
make ARCH=i386

All errors (new ones prefixed by >>):
