From 663276b7c6340e755ed62bed67a2b96f4fc3d513 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 30 Apr 2008 20:44:53 +1000 Subject: [POWERPC] Set lower flag bits in regs->trap to indicate debug level exception We use the low bits of regs->trap as flag bits. We already indicate critical and machine check level exceptions via this mechanism. Extend it to indicate debug level exceptions.
