In power_supply_create_attrs(), we create static attributes as referenced

via power_supply_static_attrs[psy->properties[i]].  This is incorrect, as
psy->properties has absolutely no bearing on static attribs.  This patch
fixes it to unregister the correct attrib.

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.

In order to fix APM emulation it is necessary to enable apm-emulation
notifications for suspends triggered in various ways via the suspend
notifiers.  However, this will cause the systems using APM emulation
to lock up between X being needed to switch away from the VT and X
already waiting for resume in the APM ioctl.

This patch moves the console switch (if enabled) before the suspend
notification (and after the resume notification) to avoid this issue.

The ACPI 1.0 specification wants us to put devices into low power
states after executing the _PTS global control method, while ACPI
2.0 and later want us to do that in the reverse order.  The current
hibernation code follows ACPI 2.0 in that respect which may cause some
ACPI 1.0x systems to hang during hibernation (ref.

The preparation to enter an ACPI system sleep state is now tied to
the disabling of GPEs, but the GPEs should not be disabled before
suspending devices.  Since on ACPI 1.0x systems the _PTS global
control method should be executed before suspending devices, we
need to disable GPEs separately.

The execution of ACPI global control methods _GTS and _BFS is
currently tied to the preparation to enter a sleep state and to the
leaving of the sleep state, respectively.  However, these functions
are called before disabling the nonboot CPUs and after enabling
them, respectively (in fact, on ACPI 1.0x systems the first of them
ought to be called before suspending devices), while according to the
ACPI specification, _GTS is to be executed right prior to entering
the system sleep state and _BFS is to be executed right after the
platfor firmware has returned control to the OS on wake up.

Move the execution of _GTS and _BFS to the right places.

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().
