kgdb, powerpc: arch specific powerpc kgdb support
This patch removes the old kgdb reminants from ARCH=powerpc and implements the new style arch specific stub for the common kgdb core interface. It is possible to have xmon and kgdb in the same kernel, but you cannot use both at the same time because there is only one set of debug hooks. The arch specific kgdb implementation saves the previous state of the debug hooks and restores them if you unconfigure the kgdb I/O driver. Kgdb should have no impact on a kernel that has no kgdb I/O driver configured. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
