    [IA64] Disable/re-enable CPE interrupts on Altix · 1f3b6045
    Russ Anderson authored
    When the CPE handler encounters too many CPEs (such as a solid single
    bit memory error), it sets up a polling timer and disables the CPE
    interrupt (to avoid excessive overhead logging the stream of single
    bit errors).  disable_irq_nosync() calls chip->disable() to provide
    a chipset specifiec interface for disabling the interrupt.  This patch
    adds the Altix specific support to disable and re-enable the CPE interrupt.
