#     
#     Pull MSI irq updates from Thomas Gleixner:
#      "Rework of the MSI interrupt infrastructure.
#     
#       This is a treewide cleanup and consolidation of MSI interrupt handling
#       in preparation for further changes in this area which are necessary
#       to:
#     
#        - address existing shortcomings in the VFIO area
#     
#        - support the upcoming Interrupt Message Store functionality which
#          decouples the message store from the PCI config/MMIO space"
