    drm/i915/gvt: fix crash in vgpu_reset_execlist · 0427f06a
    Du, Changbin authored
    We initiate vgpu->workload_q_head via for_each_engine
    macro which may skip unavailable engines. So we should
    follow this rule anywhere. The function
    intel_vgpu_reset_execlist is not aware of this. Kernel
    crash when touch a uninitiated vgpu->workload_q_head[x].
    Let's fix it by using for_each_engine_masked and skip
    unavailable engine ID. Meanwhile rename ring_bitmap to
    general name engine_mask.
