  - Make multiqueue devices which use the managed interrupt affinity
    infrastructure work on PowerPC/Pseries. PowerPC does not use the
    generic infrastructure for setting up PCI/MSI interrupts and the
    multiqueue changes failed to update the legacy PCI/MSI infrastructure.
    Make this work by passing the affinity setup information down to the
    mapping and allocation functions.

  - Move Jason Cooper from MAINTAINERS to CREDITS as his mail is bouncing
    and he's not reachable. We hope all is well with him and say thanks
    for his work over the years.
