Subject: [PATCH 3.18 014/150] swiotlb-xen: pass dev_addr to swiotlb_tbl_unmap_single

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stefano Stabellini <stefano.stabellini@...citrix.com>

commit 2c3fc8d26dd09b9d7069687eead849ee81c78e46 upstream.

Need to pass the pointer within the swiotlb internal buffer to the
swiotlb library, that in the case of xen_unmap_single is dev_addr, not
paddr.
