-The powernow-k8 driver maintains a per-cpu data-structure called powernow_data
-that is used to perform the frequency transitions. It initializes this data-
-structure only for the policy->cpu. So, accesses to this data-structure by
-other CPUs results in various problems because they would have been
-uninitialized.
-
-Specifically, if a cpu (!= policy->cpu) invokes the drivers' ->get() function,
-it returns 0 as the KHz value, since its per-cpu memory doesn't point to
-anything valid. This causes problems during suspend/resume since
-cpufreq_update_policy() tries to enforce this (0 KHz) as the current frequency
-of the CPU, and this madness gets propagated to adjust_jiffies() as well.
-Eventually, lots of things start breaking down, including the r8169 ethernet
-card, in one particularly interesting case reported by Pierre Ossman.
-
-https://bugzilla.kernel.org/show_bug.cgi?id=70311
-
-Fix this by initializing the per-cpu data-structures of _all_ the CPUs
-in the policy appropriately.
