Hi Vineet,

[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]

config: i386-randconfig-i1-201539 (attached as .config)
reproduce:
        git checkout 84881842f801639b80c8f6a0d9afbc582b33be01
        # save the attached .config to linux build tree
        make ARCH=i386
