Bug Description
An upstream patch exists to fix a bug which causes lost interrupts on the Iron Lake platform.
SRU Justification:
Impact: The interrupt handler for the Ironlake hardware is called with the master interrupt control bit disabled. This prevents any other interrupts which the code taken from older hw tries to handle. Not only this is unneeded, this also effects stability of platforms with Iron Lake hardware as interrupts get lost.
Fix: Patch taken from upstream and modified slightly to apply to Karmic.
