Since the Venki's patch has been merged in the meantime, can you please
rebase this on top of the current Linus' tree?

The PM QoS feature depends on CONFIG_PM which depends on
PM_SLEEP || PM_RUNTIME. This breaks CPU C-states with kernels
not having these CONFIGs.
This patch allows the feature in all cases.

Applied, but I modified the changelog (please have a look at the
