bump version to 1.1

intelli_plug: increase cores on persistence

also replace hardcoded values with Macros for ease of updating later

intelli_plug: make it gcc-4.6.x eabi compatible :p

intelli_plug: use rq_stats to help detect artificial or constant loads

benchmarks often create fake / artificial loads at a constant rate.  These
type of loads are not detected corectly by run average algorithms. Use
the run queue stats to help detect these cases and bring up the cores in
correspondence.

bump version to 1.2

intelli_plug: use mp_decision() algorithm for core 3 and 4

This replaces the simplistic check for run queue thresholds with a more
sophisticate algorithm with time awareness

bump version to 1.3

intelli_plug: use mp_decision to reduce online persistence count for cores

this should bring down the cores faster when run queue is low
also optimized code a bit using local vars

intelli_plug: disable by default

let the user enable via sysfs so it won't clash with mpdecision which is
enabled by default for qualcomm phones

intelli_plug: slow down hotplug activity from 50ms to 200ms

this will reduce the hotplug chaos which may in turn save more power

intelli_plug: code clean up and minor bug fixes

bump to version 1.6

intelliplug: replaced deprecated early_suspend driver with userspace interface

early_suspend has been deprecated, so move original functionality to sysfs
interfae and have userspace app to replicate the early_suspend functionality

bump version to 1.7

intelli_plug: add dynamic load sampling rate logic

Add dynamic sampling logic based on load. If load is high and required more
than 2 cores, increase the sampling rate for a duration of 3 seconds to help
manage the load better during this time.  Once duration expires, revert back
to lazier sampling rate for better batter performance.
