Michael Ellerman b2bb65f680 powerpc/xmon: Fallback to printk() in xmon_printf() if udbg is not setup ... It is possible to configure a kernel which has xmon enabled, but has no udbg backend to provide IO. This can make xmon rather confusing, as it produces no output, blocks for two seconds, and then returns. As a last resort we can instead try to printk(), which may deadlock or otherwise crash, but tries quite hard not to.
