xen: branch for v5.15-rc1

It contains the following changes:

- some small cleanups
- a fix for a bug when running as Xen PV guest which could result in
  not all memory being transferred in case of a migration of the guest
- a small series for getting rid of code for supporting very old Xen
  hypervisor versions nobody should be using since many years now
- a series for hardening the Xen block frontend driver
- a fix for Xen PV boot code issuing warning messages due to a stray
  preempt_disable() on the non-boot processors

Thanks.

Juergen
