From a0ee05670915006564962114d4211dd578a8b28a Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Thu, 9 Jun 2011 09:49:13 -0400 Subject: xen/pci: Squash pci_xen_initial_domain and xen_setup_pirqs together. Since they are only called once and the rest of the pci_xen_* functions follow the same pattern of setup.
