Currently the qmap control pkts are sent back to AP
from modem because of exception. The fix is
to use pkt_init to skip filtering/natting on IPA-HW to
reach modem instead. Also there is a requirement for
AP-side to send back qmap flow control acks immediately
after receiving the requets. The code change is to make
2st level high-watermark for those qmap control pkts to
not be dropped. Also rmnet_ipa driver won't stop queue
if the current pkt is qmap control pkt even when
outstanding pkts above the first level of
high-watermark.

DSI software does not wait for MDP_DONE ISR
before sending new frame if burst mode feature is
enabled. It leads to race condition in below case
* MDP kicks off frame-N and mdp_busy sets to true
* MDP receives new frame-N+1 and waits for
PP_DONE interrupt before sending N+1 frame.
* MDP receives PP_DONE interrupt and kicks off
frame-N+1 (DSI_MDP_DONE interrupt is not received yet).
* Frame-N+1 kickoff sets the mdp_busy wait to true.
* DSI receives DSI_MDP_DONE interrupt for frame-N and
reset the mdp_busy to false.
* Any clock off call can turn off the clock at this moment.
DSI software must always execute busy_wait when kickoff
happens from mdp. That avoids the busy wait race condition.

There are high chances for hrtimer_interrupt() interrupt on
one of the core and other core executing sys_reboot simultaneously.
In such a situation we could see ipi_cpu_stop() marking a cpu
as 'offline' but hrtimer_wakeup() can schedule a task on
offline core, resulting BUG_ON in smp_send_reschedule().
In fact that the CPU is not really offline but ipi_cpu_stop()
is marking it as offline.

This is easily reproducible in device continuous reboot testing.
Since the CPU is not really offline and hasn't gone through the

The active context tracker that we bolted on the side of the
dispatcher was designed mainly to see if there was 1 OR more than 1
active context, not much more than that. Since it is apparent that
we'll need to track up to 4 contexts and possibly more later the
algorithm needs to change.
The new algorithm puts all active contexts on a linked list - every
time a context is used it is popped from the list and put on the
tip with an updated time. To count the number of active contexts
walk the list until you get a context with an active time older than
you are looking for. You also can do other magic on the context,
like see if it matches up with a given command queue.
