This may be okay for MDS mitigation but not for\nRDFS. Because RDFS mitigation requires CPU buffers to be cleared when\nregisters don't have any sensitive data.\n\nMove CLEAR_CPU_BUFFERS after RESTORE_ALL_NMI."

Esto puede ser adecuado para la mitigaci\u00f3n de MDS, pero no para RDFS. Porque la mitigaci\u00f3n de RDFS requiere que se borren los b\u00faferes de la CPU cuando los registros no tienen datos confidenciales. Mueva CLEAR_CPU_BUFFERS despu\u00e9s de RESTORE_ALL_NMI."
