The HID layer has some scan codes of the form 0xffbc0000 for logitech
devices which do not work if scancode is typed as signed int, so we need
to switch to unsigned it instead. While at it keycode being signed does
not make much sense either.

A pointer to hp_wmi_bios_setup is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.
The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER,
and thus must check its return value before accessing
or kfree() on the buffer.

acpi_status
Emphasize that that wmi_install_notify_handler() returns an acpi_status
rather than -errno by by testing ACPI_SUCCESS(), ACPI_FAILURE().
No functional change in this patch, but this confusion caused a bug in dell-wmi.

These function allocate an acpi object by calling wmi_get_event_data, which
then calls acpi_evaluate_object, and it is not freed afterwards.
And kernel doc is fixed for parameters of wmi_get_event_data.

1) Add support for reading the hardware blocked state. Previously
we read a combination of the hardware and software blocked states,
reporting it as the software blocked state. This caused some
confusing behaviour.
2) The software state is persistent, mark it as such.
3) Check rfkill in the resume handler. Both the hard and soft
blocked states may change over hibernation.

Some systems may not support input events, or registering the input
handler may have failed. So check that an input device exists before
trying to set the docking and tablet mode state during resume.

HP tablets send a WMI event when a tablet state change occurs, but use the
same method as is used for reporting docking and undocking. The same query
is used to obtain the state of the hardware. Bit 0 indicates the docking
state, while bit 2 indicates the tablet state. This patch breaks these out
and sends separate input events for tablet and dock state changes. An
additional sysfs file is added to report the tablet state.

rfkill_set_global_sw_state() (previously rfkill_set_default()) will no
longer be exported by the rewritten rfkill core.
Instead, platform drivers which can provide persistent soft-rfkill state
across power-down/reboot should indicate their initial state by calling
rfkill_set_sw_state() before registration. Otherwise, they will be
initialized to a default value during registration by a set_block call.
We remove existing calls to rfkill_set_sw_state() which happen before
registration, since these had no effect in the old model. If these
drivers do have persistent state, the calls can be put back (subject
to testing :-). This affects hp-wmi and acer-wmi.
Drivers with persistent state will affect the global state only if
rfkill-input is enabled. This is required, otherwise booting with
wireless soft-blocked and pressing the wireless-toggle key once would
have no apparent effect. This special case will be removed in future
along with rfkill-input, in favour of a more flexible userspace daemon
(see Documentation/feature-removal-schedule.txt).
Now rfkill_global_states[n].def is only used to preserve global states
over EPO, it is renamed to ".sav".

This patch completely rewrites the rfkill core to address
the following deficiencies:
* all rfkill drivers need to implement polling where necessary
rather than having one central implementation
* updating the rfkill state cannot be done from arbitrary
contexts, forcing drivers to use schedule_work and requiring
lots of code
* rfkill drivers need to keep track of soft/hard blocked
internally -- the core should do this
* the rfkill API has many unexpected quirks, for example being
asymmetric wrt. alloc/free and register/unregister
* rfkill can call back into a driver from within a function the
driver called -- this is prone to deadlocks and generally
should be avoided
* rfkill-input pointlessly is a separate module
* drivers need to #ifdef rfkill functions (unless they want to
depend on or select RFKILL) -- rfkill should provide inlines
that do nothing if it isn't compiled in
* the rfkill structure is not opaque -- drivers need to initialise
it correctly (lots of sanity checking code required) -- instead
force drivers to pass the right variables to rfkill_alloc()
* the documentation is hard to read because it always assumes the
reader is completely clueless and contains way TOO MANY CAPS
* the rfkill code needlessly uses a lot of locks and atomic
operations in locked sections
* fix LED trigger to actually change the LED when the radio state
changes -- this wasn't done before

Almost all drivers do not support user_claim, so remove it
completely and always report -EOPNOTSUPP to userspace. Since
userspace cannot really drive rfkill _anyway_ (due to the
odd restrictions imposed by the documentation) having this
code is just pointless.

It is possible that the system gets docked or undocked while it's
suspended. Generate an input event on resume to notify user space
if there was a state change.
As it is a switch, we can generate the event unconditionally; the
input layer will only pass it on if there is an actual change.

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.
The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.
In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>
