x86: change NR_CPUS arrays in powernow-k8
Change the following static arrays sized by NR_CPUS to per_cpu data variables: powernow_k8_data *powernow_data[NR_CPUS]; Signed-off-by: Mike Travis <travis@sgi.com> Reviewed-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
