During modem WDOG bite scenarios, error handlers are not executed
in modem. So Adrastea may not be in reset when SSR notifications
are received in HLOS. Remapping MSA0 during SSR could cause SMMU
fault at Adrastea, as it may be still accessing it. Skip collecting
MSA0 dump in WDOG bite scenarios.

In some specific cases, clients may want to know why subsystem
crashed, for example, in case of watch dog bite, subsystem may not
be able to execute error handling. Which would need different code
paths to be exercised on the apps processor.

As it turns out, the KASLR code breaks CONFIG_MODVERSIONS, since the
kcrctab has an absolute address field that is relocated at runtime
when the kernel offset is randomized.
This has been fixed already for PowerPC in the past, so simply wire up
the existing code dealing with this issue.

Right now the vmpressure window is of constant size 2MB, which
works well with the following exceptions.
1) False vmpressure triggers are seen when the RAM size is greater
than 3GB. This results in lowmemorykiller, which uses vmpressure
events, killing tasks unnecessarily.
2) Vmpressure events are received late under memory pressure. This
behaviour is seen prominently in <=2GB RAM targets. This results in
lowmemorykiller kicking in late to kill tasks resulting in avoidable
page cache reclaim.
The problem analysis shows that the issue is with the constant size
of the vmpressure window which does not adapt to the varying memory
conditions. This patch recalculates the vmpressure window size at
the end of each window. The chosen window size is proportional to
the total of free and cached memory at that point.

Similar to tracking average burst length for tasks, average sleep time
indicates how much a task sleeps on an average before waking up to run.
Very low sleep and burst lengths indicates tasks that could be
sensitive to task-wake latencies and hence should not be packed.

Introduce sched_short_burst tunable to classify "short-burst" tasks.
These tasks are eligible for packing to avoid overhead associated with
waking up an idle CPU. select_best_cpu() ignores power-cost and selects
the CPU with least wakeup latency which is not loaded with IRQs and
can accommodate this task without exceeding spill limits. The ties are
broken with load followed by previous CPU.
This policy does not affect cluster selection but only CPU selection
in the selected cluster. The tasks eligible for "wakeup-up-idle" and
"boost" are not considered for packing. This policy is applied for
both "fair" and "rt" scheduling class tasks.

For a full battery, the driver currently reports battery full
only when the charger is online and switches back to reporting
discharging when charger is removed.
This is incorrect because a user might reinsert the charger
seeing discharging status right after he removes it only to
realize that the battery is full after he plugs it back.
So allow the full status to be reported even when no charger is
online.

The commit introduces a bug in scheduler book-keeping whereby if a CPU

executing tasks gets mis-attributed to interrupts. This in turn results
in unfair scheduling whereby a task can keep executing for a very long
time without any update to it's vruntime. This revert has no side
