* msm: smsm: Add processor AWAKE signaling This processor-awake signaling can be used by remote processors to determine if the Apps processor is asleep and if so, if it wants to send data to the Apps processor that would trigger a wakeup sequence.
* msm: smsm: Rename LTE Coexistence Bit
* sched: Fix select_idle_sibling() bouncing cow syndrome If the previous CPU is cache affine and idle, select it. The current implementation simply traverses the sd_llc domain, taking the first idle CPU encountered, which walks buddy pairs hand in hand over the package, inflicting excruciating pain.
