3.16.7-ckt4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>
commit d6883e6f32e07ef2cc974753ba00927de099e6d7 upstream.
xen_dma_unmap_page and xen_dma_sync_single_for_cpu take a dma_addr_t
handle as argument, not a physical address.
