From 1a9a3e76dde191f82f7a8a66059dcbb4a9f63ff3 Mon Sep 17 00:00:00 2001 From: Jason Wessel Date: Tue, 1 Apr 2008 16:55:28 -0500 Subject: kgdb: always use icache flush for sw breakpoints On the ppc 4xx architecture the instruction cache must be flushed as well as the data cache. This patch just makes it generic for all architectures where CACHE_FLUSH_IS_SAFE is set to 1.
