kgdboc: Add ekgdboc for early use of the kernel debugger
The ekgdboc= differs from kgdboc= in that you can begin debuggin as soon as the exceptions are setup and the kgdb I/O driver is available, instead of waiting until the tty subsystem is available. CC: kgdb-bugreport@lists.sourceforge.net Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
