Hi Jacob,

I love your patch! Perhaps something to improve:

[auto build test WARNING on iommu/next]
[also build test WARNING on v4.16-rc6 next-20180323]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Jacob-Pan/IOMMU-and-VT-d-driver-support-for-Shared-Virtual-Address-SVA/20180325-024555
base:   https://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git next
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

   drivers/iommu/intel-iommu.c:500:5: sparse: symbol 'intel_iommu_gfx_mapped' was not declared. Should it be static?
   drivers/iommu/intel-iommu.c:3066:41: sparse: incorrect type in argument 1 (different address spaces) @@    expected void volatile [noderef] <asn:2>*addr @@    got ile [noderef] <asn:2>*addr @@
   drivers/iommu/intel-iommu.c:3066:41:    expected void volatile [noderef] <asn:2>*addr

>> drivers/iommu/intel-iommu.c:5198:5: sparse: symbol 'intel_iommu_page_response' was not declared. Should it be static?
>> drivers/iommu/intel-iommu.c:5224:48: sparse: right shift by bigger than source value

Please review and possibly fold the followup patch.
