xen: branch for v5.6-rc1

It contains:

- a fix of a bug introduced in 5.5 for the Xen gntdev driver
- a fix of the Xen balloon driver when running on ancient Xen versions
- a patch allowing Xen stubdoms to control interrupt enable flags of
  passed-through PCI cards
- a series for releasing resources in Xen backends under memory pressure


Thanks.

Juergen
