Subject: powernow-k8: fix misleading variable naming
From: Borislav Petkov <borislav.petkov@xxxxxxx>
rdmsr() takes the lower 32 bits as a second argument and the high 32 as a
third. Fix the names accordingly since they were swapped.
There should be no functionality change resulting from this patch.
