cpufreq init can be called when a CPU is set online. Need to make powernow-k8's initialisation functions __cpuinit to prevents oopses when a CPU is off/onlined on a AMD system Cc: trenn@suse.de Cc: mark.langsdorf@amd.com Cc: davej@redhat.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
