From 17ce452f7ea3df760b7f9f42453b6f6acd765217 Mon Sep 17 00:00:00 2001 From: Jason Wessel Date: Wed, 23 Jul 2008 11:30:15 -0500 Subject: 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.
