While hunting an issue in swiotlb-xen I stumbled over a wrong test
and found some areas for improvement.
Juergen Gross (3):
xen/swiotlb: fix condition for calling xen_destroy_contiguous_region()
xen/swiotlb: simplify range_straddles_page_boundary()

same MFN. This will lead to various strange
crashes or data corruption.
Instead of calling xen_destroy_contiguous_region() in that case a
warning should be issued as that situation should never occur.
