This is caused by backporting 2f0b82b1b830 ("swiotlb-xen: implement xen_swiotlb_dma_mmap callback") into stable-rc/4.4. The ->mmap() callback signature changed in linux-4.8 as of commit 00085f1efa38 ("dma-mapping: use unsigned long for dma_attrs"), so all older kernels are affected. Please drop the backport patch from 4.4 and 3.18, or apply the trivial fixup that I'll send in a bit.
