kgdb: allow static kgdbts boot configuration
This patch adds in the ability to compile the kgdb internal test string into the kernel so as to run the tests at boot without changing the kernel boot arguments. This patch also changes all the error paths to invoke WARN_ON(1) which will emit the line number of the file and dump the kernel stack when an error occurs. You can disable the tests in a kernel that is built this way using "kgdbts=" Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
