Hi Bharat,

[auto build test ERROR on pci/next]
[also build test ERROR on v4.4 next-20160111]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]

base:   https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git next
config: arm-allyesconfig (attached as .config)
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=arm 

Note: the linux-review/Bharat-Kumar-Gogada/PCI-xilinx-Removing-xilinx_pcie_parse_and_add_res-function/20160112-133224 HEAD 8ae5c17c14eb5023b68a0c2bc9fabb3b24eab051 builds fine.
      It only hurts bisectibility.
