iommu/amd: Pass gfp flags to iommu_map_page() in amd_iommu_map()
commit3057fb9377
upstream. A recent commit added a gfp parameter to amd_iommu_map() to make it callable from atomic context, but forgot to pass it down to iommu_map_page() and left GFP_KERNEL there. This caused sleep-while-atomic warnings and needs to be fixed. Reported-by: Qian Cai <cai@lca.pw> Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Fixes:781ca2de89
