From 21cb20d758254e68a369ba83c721f8ce083e6659 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 11 Apr 2012 10:48:24 +0900 Subject: sh: kgdb: Unset CACHE_FLUSH_IS_SAFE for SMP. Our SMP cache flush ops use CPU cross calls to deal with things like I-cache accesses not being broadcast in hardware, so ensure that the CACHE_FLUSH_IS_SAFE reflects this.
