[PATCH v2 0/2] x86/xen: simplify irq pvops

[Juergen Gross]

The pvops function for Xen PV guests handling the interrupt flag are
much more complex than needed.

With the supported Xen hypervisor versions they can be simplified a
lot, especially by removing the need for disabling preemption.

Juergen Gross (2):
  x86/xen: remove xen_have_vcpu_info_placement flag
  x86/xen: switch initial pvops IRQ functions to dummy ones
