x86/intel_rdt: Discover supported platforms via prefetch disable bits Knowing the model specific prefetch disable bits is required to support cache pseudo-locking because the hardware prefetchers need to be disabled when the kernel memory is pseudo-locked to cache. We add these bits only for platforms known to support cache pseudo-locking. When the user requests locksetup mode to be entered it will fail if the prefetch disabling bits are not known for the platform.
