Hi He,

[auto build test ERROR on kvm/linux-next]
[also build test ERROR on v4.9-rc5]
[cannot apply to next-20161114]
[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/He-Chen/x86-kvm-Add-AVX512_4VNNIW-and-AVX512_4FMAPS-support/20161114-170941
base: https://git.kernel.org/pub/scm/virt/kvm/kvm.git linux-next
config: x86_64-kexec (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=x86_64
