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? ? - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
