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().
