Sorry, i made a mistake. The error is as follows:

drivers/gpu/drm/i915/gt/intel_ggtt.c: In function ggtt_restore_mappings:
drivers/gpu/drm/i915/gt/intel_ggtt.c:1239:3: error: implicit declaration of function wbinvd_on_all_cpus; did you mean wrmsr_on_cpus? [-Werror=implicit-function-declaration]
   wbinvd_on_all_cpus();
   ^~~~~~~~~~~~~~~~~~
   wrmsr_on_cpus


Thanks,
