From b950bdd0fc247d0ab4aea88d46e8cced3eac949e Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 18 Aug 2008 14:23:51 +1000 Subject: powerpc: Expose PMCs & cache topology in sysfs on 32-bit The file arch/powerpc/kernel/sysfs.c is currently only compiled for 64-bit kernels. It contain code to register CPU sysdevs in sysfs and add various properties such as cache topology and raw access by root to performance monitor counters (PMCs). A lot of that can be re-used as is on 32-bits. This makes the file be built for both, with appropriate ifdef'ing for the few bits that are really 64-bit specific, and adds some support for the raw PMCs for 75x and 74xx processors.
