From CMN-650 onwards, some of the fields in the watchpoint config
registers moved subtly enough to easily overlook. Watchpoint events are
still only partially supported on newer IPs - which in itself deserves
noting - but were not intended to become any *less* functional than on
CMN-600.

 "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"
