From: Xie XiuQi <xiexi...@huawei.com> Using "mce=1,10000000" on the kernel cmdline to change the monarch timeout does not work. The cause is that get_option() does parse a subsequent comma in the option string and signals that with a return value. So we don't need to check for a second comma ourselves.
