From 358c6ac0dd4ffa5e44d59d4008a2627aa2f02b6f Mon Sep 17 00:00:00 2001 From: Ananth N Mavinakayanahalli Date: Wed, 8 Jun 2005 15:33:43 +1000 Subject: [PATCH] [PATCH] ppc64 kprobes: don't eat dabr/iabr exceptions Kprobes was eating the hardware instruction and data address breakpoint exceptions. This patch fixes it; kprobes doesn't use those exceptions at all and should ignore them.
