power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL
The CAPACITY_LEVEL stuff defines various levels of charge; however, what
is the difference between them? What differentiates between HIGH and NORMAL,
LOW and CRITICAL, etc?
As it appears that these are fairly arbitrary, we end up making such policy
decisions in the kernel (or in hardware). This is the sort of decision that
should be made in userspace, not in the kernel.
If the hardware does not support _CAPACITY and it cannot be easily calculated,
then perhaps the driver should register a custom CAPACITY_LEVEL attribute;
however, userspace should not become accustomed to looking for such a thing,
and we should certainly not encourage drivers to provide CAPACITY_LEVEL
stubs.
The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The
OLPC battery driver is the only driver making use of this, so it's
removed from there as well.

On ACPI systems the target state set by acpi_pm_set_target() is
reset by acpi_pm_finish(), but that need not be called if the
suspend fails. All platforms that use the .set_target() global
suspend callback are affected by analogous issues.
For this reason, we need an additional global suspend callback that
will reset the target state regardless of whether or not the suspend
is successful. Also, it is reasonable to rename the .set_target()
callback, since it will be used for a different purpose on ACPI
systems (due to ACPI 1.0x code ordering requirements).
Introduce the global suspend callback .end() to be executed at the
end of the suspend sequence and rename the .set_target() global
suspend callback to .begin().

Hibernation: New testing facility (rev. 2)
Make it possible to test the hibernation core code with the help of the
/sys/power/pm_test attribute introduced for suspend testing in the previous
patch.
Writing an appropriate string to this file causes the hibernation code to work
in one of the test modes defined as follows:
freezer
- test the freezing of processes
devices
- test the freezing of processes and suspending of devices
platform
- test the freezing of processes, suspending of devices and platform global
control methods(*)
processors
- test the freezing of processes, suspending of devices, platform global
control methods(*) and the disabling of nonboot CPUs
core
- test the freezing of processes, suspending of devices, platform global
control methods(*), the disabling of nonboot CPUs and suspending of
platform/system devices
(*) - the platform global control methods are only available on ACPI systems
and are only tested if the hibernation mode is set to "platform"
Then, if a hibernation is started by normal means, the hibernation core will
perform its normal operations up to the point indicated by given test level.
Next, it will wait for 5 seconds and carry out the resume operations needed to
transition the system back to the fully functional state.

Suspend: Testing facility (rev. 2)
Introduce sysfs attribute /sys/power/pm_test allowing one to test the suspend

to this file causes the suspend code to work in one of the test modes defined as

(*) These are ACPI global control methods on ACPI systems
Then, if a suspend is started by normal means, the suspend core will perform
its normal operations up to the point indicated by given test level. Next, it
will wait for 5 seconds and carry out the resume operations needed to transition
the system back to the fully functional state.
Writing "none" to /sys/power/pm_test turns the testing off.
When open for reading, /sys/power/pm_test contains a space-separated list of all
available tests (including "none" that represents the normal functionality) in
which the current test level is indicated by square brackets.

Modify the hibernation userland interface by adding two new ioctls to it,
SNAPSHOT_PLATFORM_SUPPORT and SNAPSHOT_POWER_OFF, that can be used,

PCI: make pci_bus a struct device
This moves the pci_bus class device to be a real struct device and at
the same time, place it in the device tree in the correct location.
Note, the old "bridge" symlink is now gone, but this was a non-standard
link and no userspace program used it. If you need to determine the
device that the bus is on, follow the standard device symlink, or walk
up the device tree.
