From: Leon Romanovsky <leonro@nvidia.com> Block layer maps MMIO memory through dma_map_phys() interface with help of DMA_ATTR_MMIO attribute. There is a need to unmap that memory with the appropriate unmap function, something which wasn't possible before adding new REQ attribute to block layer in previous patch.
