From 56ddf4d3cf04e80254d3d721c6bea2f8ec44c41a Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 13 Nov 2009 17:34:29 -0700 Subject: x86/PCI: MMCONFIG: add resource to struct pci_mmcfg_region This patch adds a resource and corresponding name to the MMCONFIG structure. This makes allocation simpler (we can allocate the resource and name at the same time we allocate the pci_mmcfg_region), and gives us a way to hang onto the resource after inserting it. This will be needed so we can release and free it when hot-removing a host bridge.
