-stable review patch.  If anyone has any objections, please let us know.

From: Dave Jones <davej@redhat.com>

[CPUFREQ] Make powernow-k7 work on SMP kernels.
Even though powernow-k7 doesn't work in SMP environments,
it can work on an SMP configured kernel if there's only
one CPU present, however recalibrate_cpu_khz was returning
-EINVAL on such kernels, so we failed to init the cpufreq driver.
