From 244bc050d5c9431682b7d834aff92e663fe88bb2 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 22 Sep 2005 21:43:55 -0700 Subject: [PATCH] [PATCH] ppc32: fix build with oprofile Current -git tree doesn't build when enabling oprofile on a non-bookE CPU (like on a PowerMac for example). While there is no performance counter support for these CPUs implemented yet, it's still nice to be able to use the timer based sampling, and that got broken.
