[PATCH 4/5 v2] pseries/iommu: implement DDW-aware dma_get_page_shift

[kbuild test robot]

Hi Nishanth,

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

config: powerpc-defconfig (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=powerpc 

All error/warnings (new ones prefixed by >>):

   arch/powerpc/platforms/pseries/iommu.c: In function 'iommu_init_early_pSeries':
>> arch/powerpc/platforms/pseries/iommu.c:1433:9: error: 'struct machdep_calls' has no member named 'dma_get_page_shift'
      ppc_md.dma_get_page_shift = dma_get_page_shift_pSeriesLP;
