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.

Many thanks for the fixup, I've queued that up now for both trees.
