Currently cpuidle drivers are spread across different archs.
As a result, there are several different paths for cpuidle patch
submissions: cpuidle core changes go through linux-pm, ARM driver
changes go to the arm-soc or SoC-specific trees, sh changes go
through the sh arch tree, pseries changes go through the PowerPC tree
and finally intel changes go through the Len's tree while ACPI idle
changes go through linux-pm.
That makes it difficult to consolidate code and to propagate
modifications from the cpuidle core to the different drivers.
Hopefully, a movement has started to put the majority of cpuidle
drivers under drivers/cpuidle like cpuidle-calxeda.c and
cpuidle-kirkwood.c.
Add a maintainer entry for cpuidle to MAINTAINERS to clarify the
situation and to indicate to new cpuidle driver authors that those
drivers should not go into arch-specific directories.
The upstreaming process is unchanged: Rafael takes patches for
merging into his tree, but with an Acked-by: tag from the driver's
maintainer, so indicate in the drivers' headers who maintains them.
The arrangement will be the same as for cpufreq.

Commit 4ae46be "Thermal: Introduce thermal_zone_trip_update()"
introduced a regression causing the fan to be always on even when
the system is idle.
My original idea in that commit is that:
- when the current temperature is above the trip point,
keep the fan on, even if the temperature is dropping.
- when the current temperature is below the trip point,
turn on the fan when the temperature is raising,
turn off the fan when the temperature is dropping.
But this is what the code actually does:
- when the current temperature is above the trip point,
the fan keeps on.
- when the current temperature is below the trip point,
the fan is always on because thermal_get_trend()
in driver/acpi/thermal.c returns THERMAL_TREND_RAISING.
Thus the fan keeps running even if the system is idle.
Fix this in drivers/acpi/thermal.c.

acpi_video_bus_get_devices() may fail due to some video output device
doesn't have the _ADR method, and in this case, the error processing
is to simply free the video structure in acpi_video_bus_add(), while
leaving those already registered video output devices in the wild,
which means for some video output device, we have already registered
a backlight interface and installed a notification handler for it.
So it can happen when user is using this system, on hotkey pressing,
the notification handler will send a keycode through a non-existing
input device, causing kernel freeze.
To solve this problem, free all those already registered video output
devices once something goes wrong in acpi_video_bus_get_devices(), so
that no wild backlight interfaces and notification handlers exist.

Commit 53aac44 (ACPI: Store valid ACPI tables passed via early initrd
in reserved memblock areas) introduced acpi_initrd_override() that
passes a wrong value as the second argument to memblock_reserve().
Namely, the second argument of memblock_reserve() is the size of the
region, not the address of the top of it, so make
acpi_initrd_override() pass the size in there as appropriate.

The code intializes the cpuidle driver at different places.
The cpuidle driver for :
* imx5 : is in the pm-imx5.c, the init function is in cpuidle.c
* imx6 : is in cpuidle-imx6q.c, the init function is in cpuidle.c
and cpuidle-imx6q.c
Instead of having the cpuidle code spread across different files,
let's create a driver for each SoC and use the common register function.

The usual scheme to initialize a cpuidle driver on a SMP is:
cpuidle_register_driver(drv);
for_each_possible_cpu(cpu) {
device = &per_cpu(cpuidle_dev, cpu);
cpuidle_register_device(device);
}
This code is duplicated in each cpuidle driver.
On UP systems, it is done this way:
cpuidle_register_driver(drv);
device = &per_cpu(cpuidle_dev, cpu);
cpuidle_register_device(device);
On UP, the macro 'for_each_cpu' does one iteration:
#define for_each_cpu(cpu, mask) \
for ((cpu) = 0; (cpu) < 1; (cpu)++, (void)mask)
Hence, the initialization loop is the same for UP than SMP.
Beside, we saw different bugs / mis-initialization / return code unchecked in
the different drivers, the code is duplicated including bugs. After fixing all
these ones, it appears the initialization pattern is the same for everyone.
Please note, some drivers are doing dev->state_count = drv->state_count. This is
not necessary because it is done by the cpuidle_enable_device function in the
cpuidle framework. This is true, until you have the same states for all your
devices. Otherwise, the 'low level' API should be used instead with the specific
initialization for the driver.
Let's add a wrapper function doing this initialization with a cpumask parameter
for the coupled idle states and use it for all the drivers.
That will save a lot of LOC, consolidate the code, and the modifications in the
future could be done in a single place. Another benefit is the consolidation of
the cpuidle_device variable which is now in the cpuidle framework and no longer
spread accross the different arch specific drivers.

All the drivers are using, in their initialization function, the
for_each_possible_cpu macro.
Using for_each_online_cpu means the driver must handle the initialization
of the cpuidle device when a cpu is up which is not the case here.
Change the macro to for_each_possible_cpu as that fix the hotplug
initialization and make the initialization routine consistent with the
rest of the code in the different drivers.

Currently we decide if the _BQC is using index by first setting the
level to maximum, and then check if _BQC returned maximum; if not, we
say it is using index.
This is not true for some buggy systems, where the _BQC method will
always return a constant value(e.g. 0 or 100 for the two broken system)
and thus break the current logic. So this patch tries to enhance the
quirk detect logic for _BQC: we do this by picking a test_level, it can
be the maximum level or the mininum one based on some condition. And we
don't make the assumption that if _BQC returned a value that is not what
we just set, it must be using an index. Instead, we will compare the
value returned from _BQC and if it doesn't match, see if the returned
value is an index. And if still no, clear the capability of _BQC.

In a previous commit the en_core_tk_irqen flag has been added but we missed
the cpuidle_wrap_enter which was doing the job to measure the time for the
'omap3_enter_idle' function.
Actually, I don't see any reason to use this wrapper in the code. In the better
case, the time computation is not correctly done because of the different
operations done in omap3_enter_idle_bm which were not taken into account
before the en_core_tk_irqen flag was set.
As the time is reflected for the state overridden by the omap3_enter_idle_bm,
using the wrapper is pointless now, so removing it.

Pull kdump fixes from Peter Anvin:
"The kexec/kdump people have found several problems with the support
for loading over 4 GiB that was introduced in this merge cycle. This
is partly due to a number of design problems inherent in the way the
various pieces of kdump fit together (it is pretty horrifically manual
in many places.)
After a *lot* of iterations this is the patchset that was agreed upon,
but of course it is now very late in the cycle. However, because it
changes both the syntax and semantics of the crashkernel option, it
would be desirable to avoid a stable release with the broken
interfaces."
