From 72e42f0370f62ade4c6c2c0ab031c68fbe63e9be 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.
