-Subject: ACPI/PCI: PCI extended config _OSC support called when root bridge added
-Patch-mainline: 2.6.29
-References: bnc#438941
-
-The _OSC capability OSC_EXT_PCI_CONFIG_SUPPORT is set when the root
-bridge is added with pci_acpi_osc_support() if we can access PCI
-extended config space.
-
-This adds the function pci_ext_cfg_avail which returns true if we can
-access PCI extended config space (offset greater than 0xff). It
-currently only returns false if arch=x86 and raw_pci_ext_ops is not set
-(which might happen if pci=nommcfg is set on the kernel command-line).
