v1 -> v2: Address review comment on mm/memory.c. Add EXPORT_SYMBOL for vm_insert_range and corrected the documentation part for this API. In drivers/gpu/drm/xen/xen_drm_front_gem.c, replace err with ret as suggested. In drivers/iommu/dma-iommu.c, handle the scenario of partial mmap() of large buffer by passing *pages + vma->vm_pgoff* to vm_insert_range(). v2 -> v3: Declaration of vm_insert_range() moved to include/linux/mm.h v3 -> v4: Address review comments. In mm/memory.c. Added error check. In arch/arm/mm/dma-mapping.c, remove part of error check as the similar is checked inside vm_insert_range. In rockchip/rockchip_drm_gem.c, vma->vm_pgoff is respected as this might be passed as non zero value considering partial mapping of large buffer. In iommu/dma-iommu.c, count is modifed as (count - vma->vm_pgoff) to handle partial mapping scenario in v2. v4 -> v5: Address review comment on [2/9] and [4/9] In arch/arm/mm/dma-mapping.c, added the error check which was removed in v4, as without those error check we might end up overrun the page array. In rockchip/rockchip_drm_gem.c, added error check which was removed in v1, as without this it might overrun page array. Adjusted page_count parameter before passing it to vm_insert_range().
