   4 Subject: ACPI/PCI: PCI MSI _OSC support capabilities called when root bridge added
   5 Patch-mainline: 2.6.29
   6 References: bnc#438941
   7
   8 The _OSC capability OSC_MSI_SUPPORT is set when the root bridge is added
   9 with pci_acpi_osc_support(), so we no longer need to do it in the PCI
  10 MSI driver.  Also adds the function pci_msi_enabled, which returns true
  11 if pci=nomsi is not on the kernel command-line.
