[PATCH v3 0/3] xen/swiotlb: fix an issue and improve swiotlb-xen

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() xen/swiotlb: remember having called xen_create_contiguous_region()
