Hi Serge,

[auto build test ERROR on ntb/ntb-next]
[also build test ERROR on v4.9-rc7 next-20161130]
[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/Serge-Semin/NTB-Alter-kernel-API-to-support-multi-port-devices/20161201-014939
base: https://github.com/jonmason/ntb ntb-next
config: x86_64-randconfig-s5-12010242 (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

Note: the linux-review/Serge-Semin/NTB-Alter-kernel-API-to-support-multi-port-devices/20161201-014939 HEAD ced946cf007084caf9a2ec237c898bbf1940b440 builds fine.
