Chris Wilson a167b1e131 drm/i915: Pull intel_uncore_arm_unclaimed_mmio_detection() under the spinlock ... Elsewhere we manipulate uncore.unclaimed_mmio_check and i915_param.mmio_debug under the irq lock (e.g. preserving the current value across a user forcewake grab), but do not protect the manipulation inside intel_uncore_arm_unclaimed_mmio_detection() from concurrent access, even from itself. This is an issue as we do call arm_unclaimed_mmio_detection from multiple threads without coordination.
