path\n\n__sev_platform_init_handle_init_ex_path() calls\nrmp_mark_pages_firmware() with locked=false while the parent\nfunction of init_ex_path already acquired the sev_cmd_mutex.\nIn the case of an RMPUPDATE failure for any page after the first, the cleanup\npath would invoke reclaim pages which would result in a deadlock in\nsev_do_cmd.\n\nPass locked=true to honor the lock status of the parent
