values should overlap, see struct load, level 0 is obviously a dummy to make it better readable, level 1 is cpu0 but means "one cpu online" etc.

thanks a lot

msm: hotplug: Revert to original thresholds
msm: hotplug: Protect load stats routine and cleanup
msm: hotplug: Fix licensing issue

I have no idea about licensing and I could care less
but this should be correct.
msm: hotplug: Cleanup probe function

After performing nicely for over a half year this
actually starts looking almost decent...

thanks
@myfluxi
Fantastic Developer
msm: hotplug: two is better than one for cpus
msm: hotplug: Add enable/disable toggle

This is mainly for debugging purposes, i.e. using mpdecision.
msm: hotplug: Handle down lock per cpu

Handling down lock per cpu is more precise. We can now distinguish
between a regular interval and a generous time online after the last
input event, where it's likely that the user will interact with the
UI within then next few seconds again.
msm: hotplug: Remove unused include
msm: hotplug: Honor enabled toggle

Start workqueue only if enabled. Also queue remove down
lock work on cpu0, circumvent regular cpu down routine
when disabling hotplug work and remove complete nonsense
in store_min_cpus_online().
msm: hotplug: set min cpu to 1, add fb notifier

Thanks a lot:

msm: hotplug: Terminate load thresh table
msm: hotplug: Lower load thresholds for more interactive response
msm: hotplug: Consider projected load after cpu offlined

Don't offline a cpu if we would drop under the lower
level's up threshold load. Also, add an optional hard
threshold load under which a cpu is never offlined.
Both is especially important for very short forced
online intervals.
Revert "msm: hotplug: Lower load thresholds for more interactive response"

This reverts commit ef60a215f7178a5fe5e5e879e1fe51a97d7b5ff6.
