The maximum command line length is now dependent on the kernel image that is loaded. Therefore move the check to check_common_ipl_data(). This function now reads the new kernel image, and check whether the command line length is in the allowed range. The command line size limit in zipl is now set to 64k, which is hopefully enough.
