[PATCH v2 0/2] xen/swiotlb: two fixes

[Juergen Gross <jgross@xxxxxxxx>]

Patch 1 removes an unneeded alignment requirement, which resulted in
exhausting the SWIOTLB with normal use cases.

Patch 2 allows to allocate larger continuous regions by reallocating
the frame list if needed.

Changes in V2:
- drop former patch 2 for now in order to avoid more lengthy discussion
- new patch 2

Juergen Gross (2):
  xen/swiotlb: relax alignment requirements
  x86/xen: allow larger contiguous memory regions in PV guests
