[PATCH RESEND 00/16] Thermal: generic thermal layer enhancement

[Zhang Rui <rui.zhang@intel.com>]

Hi, all,

This is the refreshed patch set for linux-next.

the changes includes
- fixing a build error.
- making a couple of changes based on Rafael's comments
- removing the plist patch for now as I do not have validate data to show how much benefit it brings.

This patch set contains two patches from Durga,
one patch for documentation update,
and 13 patches to fix the problems discussed in
http://marc.info/?l=linux-acpi&m=133836783425764&w=2

please kindly review.

1) patch 1, 2, introduce the writeable trip point,
   and introduce hysterisis information for each trip point.
2) patch 3 is a Documentation update.
3) patch 4, 5, 6, introduce the multiple cooling states support
   for both active and passive trip points.
4) patch 7, 8, remove passive specific requirement, aka, tc1/tc2, and
   introduce .get_trend() instead, for both active and passive cooling
   algorithm.
5) patch 9 introduces new function thermal_zone_trip_update(),
   which contains the code for general cooling algorithm.
6) patch 10, 11, 12, 13 rename some thermal structures.
7) patch 14 introduces a simple cooling state arbitrator.
8) patch 15 unifies the code for both passive and active cooling.
9) patch 16 add lock for cdev.thermal_instances list.

Any comments are welcome.

thanks,
rui
