I expect you mean the new message on "boostable" CPUs which is unrelated to the
rest:
> powernow-k8: Core Performance Boosting: on.
can get mixed up with below:
> powernow-k8:    0 : pstate 0 (3200 MHz)
> powernow-k8:    1 : pstate 1 (2400 MHz)
especially the "Core performance" string by bad luck looks related:
Core Performance
0 :  pstate 0
1 :  pstate 1

I agree that this is a bit confusing and Rui's first part of the patch should
be sufficient:
             if (cpu_family == CPU_HW_PSTATE) {
                 printk(KERN_INFO PFX
-                    "   %d : pstate %d (%d MHz)\n", j,
+                    "   pstate %d (%d MHz)\n",
                     data->powernow_table[j].index,
                     data->powernow_table[j].frequency/1000);

In the other case this message:
> powernow-k8: Core Performance Boosting: on.
doesn't appear anyway and the message has another format and the bit removed by
Rui has some meaning.

But this is a really minor bug.
I hope I do not forget about it and I will add Rui's first part if I have other
cpufreq patches in the queue -> I set this one resolved already.
