Bug Description

SRU justification:

Impact: This has been reported through AMD. There is a bug in the frequency governor which prevents the P-states to be correctly set (no boost).

Fix: This fix has been queued up to linux-next and will be included in stable as well. To improve performance sooner we would be carrying this patch as pre-stable.

Testcase: Checking CPU frequencies the boost state without the patch will never be reached.

The patch noted to resolve this issue is already included in the mainline kernel as of v2.6.34-rc7. As such this patch is already included in the 2.6.35 based Maverick kernel. Thus I'm closing the Maverick nomination as Fix Released. Thanks.
