[Xen-devel] [PATCH] 2.6.39 patch for Xen IRQ rework.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

It is one single patch that I spotted while trying to make MSI/MSI-X of SR-IOV
devices work under DomU PV guests.


Konrad Rzeszutek Wilk (1):
      xen/irq: Cleanup up the pirq_to_irq for DomU PV PCI passthrough guests as 
well.
