Jean Delvare 2d58d7ea91 thermal: Rename generate_netlink_event
It doesn't seem right for the thermal subsystem to export a symbol
named generate_netlink_event. This function is thermal-specific and
its name should reflect that fact. Rename it to
thermal_generate_netlink_event.

R.Durgadoss 4cb1872870 thermal: Add event notification to thermal framework
This patch adds event notification support to the generic
thermal sysfs framework in the kernel. The notification is in the
form of a netlink event.

Frans Pop 3d8e3ad879 thermal: add sanity check for the passive attribute
Values below 1000 milli-celsius don't make sense and can cause the
system to go into a thermal heart attack: the actual temperature
will always be lower and thus the system will be throttled down to
its lowest setting.

An additional problem is that values below 1000 will show as 0 in
/proc/acpi/thermal/TZx/trip_points:passive.

cat passive
0
echo -n 90 >passive
bash: echo: write error: Invalid argument
echo -n 90000 >passive
cat passive
90000

Frans Pop 38bb0849a6 thermal: sysfs-api.txt - reformat for improved readability
The document currently uses large indentations which make the text
too wide for easy readability. Also improve general consistency.
