This patchset enables GVT suspend/resume so that GVT enabled VM can continue running after host resuming from suspend state. V2: - Change kzalloc/kfree to vzalloc/vfree since the space allocated from kmalloc may not enough for all saved GGTT entries. - Keep gvt suspend/resume wrapper in intel_gvt.h/intel_gvt.c and move the actual implementation to gvt.h/gvt.c. (zhenyu) - Check gvt config on and active with intel_gvt_active().
