  Log:
  MFC: Revamp the MSI/MSI-X code a bit to achieve two main goals:
  - Simplify the amount of work that has be done for each architecture by
    pushing more of the truly MI code down into the PCI bus driver.
  - Don't bind MSI-X indicies to IRQs so that we can allow a driver to map
    multiple MSI-X messages into a single IRQ when handling a message
    shortage.
  
  Note that as with the previous MSI MFC, this does not yet include the
  'pci_remap_msix()' function.
