Revert "[CPUFREQ][2/2] preregister support for powernow-k8"
This reverts commit 34ae7f35a21694aa5cb8829dc5142c39d73d6ba0, which has
been reported to cause a number of problems. During suspend and resume,
it apparently causes a crash in a CPU hotplug notifier to happen,
although the exact details are sketchy because of the inability to get
good traces during the suspend sequence.
See buzilla entries
http://bugzilla.kernel.org/show_bug.cgi?id=11296
http://bugzilla.kernel.org/show_bug.cgi?id=11339
for more examples and details.
[ Mark: "Revert the patch for now. I'm still looking into getting a
reliable reproduction and I do not have a fix at this time." ]
