[PATCH v5 00/14] Remove DMA map_page/map_resource and their unmap callbacks

[Leon Romanovsky <leon@kernel.org>]

This series is a combination of previous two steps [1, 2] to reduce
number of accesses to struct page in the code "below" DMA layer.

In this series, the DMA .map_page/.map_resource/.unmap_page/.unmap_resource
callbacks are converted to newly introduced .map_phys/.unmap_phys interfaces.
