[kbuild test robot]

Hi Jian,

[auto build test ERROR on v4.3-rc6 -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url:    https://github.com/0day-ci/linux/commits/Jian-Zhou/KVM-X86-Add-arrays-to-save-restore-LBR-MSRs/20151023-172601
config: x86_64-lkp (attached as .config)
reproduce:
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: the linux-review/Jian-Zhou/KVM-X86-Add-arrays-to-save-restore-LBR-MSRs/20151023-172601 HEAD d402c03a709c1dff60e2800becbafaf3b2d86dcd builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
