Move the init sections to the end of memory so that after they
are free, run time memory is all continugous - this should help decrease
memory fragementation.
When doing this, we also pack some of the other sections a little closer
together, to make sure we don't waste memory. To make this happen,
we need to rename the .data.init_task section to .init_task.data, so
it doesn't get picked up by the linker script glob.

According to ACPI spec, the _TSD object provides T-state control cross
logical processor dependency information to OSPM. So the t-state
coordination should be considered when T-state for one cpu is changed.
According to ACPI spec, three types of coordination are defined.
SW_ALL, SW_ANY and HW_ALL.
SW_ALL: it means that OSPM needs to initiate T-state transition on
all processors in the domain. It is necessary to call throttling set function
for all affected cpus.
SW_ANY: it means that OSPM may initiate T-state transition on any processor in
the domain.
HW_ALL: Spec only says that hardware will perform the coordination and doesn't
recommend how OSPM coordinate T-state among the affected cpus. So it is treated
as the type of SW_ALL. It means that OSPM needs to initiate t-state transition
on all the processors in the domain.

The t-state coordination should be considered when T-state for one cpu
is changed.It means that OSPM should select one proper target T-state for
the all affected cpus before updating T-state.
So the function of acpi_processor_throttling_notifier is added.
Before updating T-state it can be called for all the affected cpus to get
the proper target T-state, which can meet the requirement of thermal, user and
_TPC. After updating T-state, it can be called to update T-state flag.

Accordint to ACPI spec, the _TSD object provides T-state control cross
logical processor dependency information to OSPM.
After the _TSD data for all cpus are obtained, OSPM will set up
the T-state coordination between CPUs.
Of course if the _TSD doesn't exist or _TSD data is incorrect , it is
assumed that there is no T-state coordination and T-state is changed
independently.
Now there is no proper solution to update T-state coordination after
one cpu is hotplugged. So this patch won't support hotplugged cpu very well.

Vendors often ship machines with a choice of integrated or discrete
graphics, and use the same DSDT for both. As a result, the ACPI video
module will locate devices that may not exist on this specific platform.
Attempt to determine whether the device exists or not, and abort the
device creation if it doesn't.

Register ACPI processor as thermal cooling devices.
A combination of processor T-state and P-state are used for thermal throttling.
the processor will reduce the frequency first and then set the T-state.
we use cpufreq_thermal_reduction_pctg to calculate the cpufreq limit,
and call cpufreq_verify_with_limit to set the cpufreq limit.
if cpufreq driver is loaded, then we have four cooling state for cpufreq control.
cooling state 0: cpufreq limit == max_freq
cooling state 1: cpufreq limit == max_freq * 80%
cooling state 2: cpufreq limit == max_freq * 60%
cooling state 3: cpufreq limit == max_freq * 40%
after the cpufreq limit is set to 40 percentage of the max_freq,
we use T-state for cooling.
eg. a processor has P-state support, and it has 8 T-state (T0-T7),
the max_state of the proceesor is 10:
state cpufreq-limit T-state
0: max_freq T0
1: max_freq * 80% T0
2: max_freq * 60% T0
3: max_freq * 40% T0
4: max_freq * 40% T1
5: max_freq * 40% T2
6: max_freq * 40% T3
7: max_freq * 40% T4
8: max_freq * 40% T5
9: max_freq * 40% T6
10: max_freq * 40% T7

Change the ACPI thermal action upon notification 0x81 and 0x82.
According to the ACPI spec, we should:
re-evaluate _PSV and _ACx methods upon notification 0x81
re-evaluate _PSL and _ALx and _TZD upon notificaiton 0x82.
But the current code re-evaluates all the trip points for 0x81 while
only re-evaluates _TZD for 0x82.
Fix this violation of ACPI spec.
TODO: devices in _PSL, _ALx and _TZD may change after a notification 0x82.
At this time, we need to re-bind the cooling devices with the thermal zone.

Register ACPI thermal zone as thermal zone device.
the new sys I/F for ACPI thermal zone will be like this:
/sys/class/thermal:
|thermal_zone1:
|-----type: "ACPI thermal zone". RO
|-----temp: the current temperature. RO
|-----mode: the current working mode. RW.
the default value is "kernel" which means thermal
management is done by ACPI thermal driver.
"echo user > mode" prevents all the ACPI thermal driver
actions upon any trip points.
|-----trip_point_0_temp: the threshold of trip point 0. RO.
|-----trip_point_0_type: "critical". RO.
the type of trip point 0

The sysfs backlight class provides no mechanism for querying the
acceptable brightness for a backlight. The ACPI spec states that values
are only valid if they are reported as available by the firmware. Since
we can't provide that information to userspace, instead collapse the
range to the number of actual values that can be set.
