Hi all,

Here is a the v2 improving EAS estimation precision. The v1 and discussion
can be found at:
https://lore.kernel.org/lkml/20210625152603.25960-1-lukasz.luba@arm.com/

changes:
v2:
- dropped first two patches
- implemented better resolution for 64-bit only machines according to
  Peter's comment and scale_load() example
- power value multiplied by 1000 not 10000
- added 'Fixes' tag, so it could be picked into stable trees easily
- extended patch descirpion with example corenr case scenario

Regards,
Lukasz

I shouldn't have sent to CC -stable for now.
I will create and send a dedicated patch for stable
with proper commit ID after it's merged (like I did last time).
We are heading to stable 5.4+ (so the Android could get it).

Lukasz
