[PATCH v2 0/3] xen/swiotlb: fix an issue and improve swiotlb-xen

[Juergen Gross <jgross@xxxxxxxx>]

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()
