So in fact to follow up on this, looks like one of two changes are needed:

1. Revert 3db11fe


2. If CONFIG_CPU_IDLE=n, the driver needs to call disable_hlt() in place 
of the pm_qos constraint add, and call enable_hlt() in place of the pm_qos 
constraint remove.

Jean, could you please pick a solution and send a patch for the 3.7-rc 
timeframe, to fix the bug in 3db11fe?
