commit: 0459ba0b0d50429500b6ed46d0a97203de37ba6b [45/50] PCI/AER: Use threaded IRQ for bottom half
config: sh-sdk7786_defconfig (attached as .config)
compiler: sh4-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 0459ba0b0d50429500b6ed46d0a97203de37ba6b
        # save the attached .config to linux build tree
        GCC_VERSION=7.2.0 make.cross ARCH=sh 

Note: the pci/pci/hotplug HEAD 5a076cc998d369f701104e35d5bb985cab0a66d3 builds fine.
      It only hurts bisectibility.
