The series includes changes for the mei driver: - add ability to use polling instead of interrupts - add ability to use extended timeouts - setup extended operational memory for GSC The series includes changes for the i915 driver: - allocate extended operational memory for GSC - GSC on XeHP SDV offsets and definitions Greg KH, please review and ACK the MEI patches. We are pushing these patches through gfx tree as the auxiliary device belongs there.
