This code is required to keep the thinkpad-acpi maintainer sane, and
it is disabled by default.

Add a debug facility to simulate an rfkill hardware rocker switch, a
bluetooth rfkill soft-switch, a WWAN rfkill soft-switch on thinkpads.

The simulated switches obviously do not kill any radios in hardware or
firmware (unlike the real one).  They also don't issue deprecated proc
events.

These are platform specific drivers that happen to use ACPI,
while drivers/acpi/ is for code that implements ACPI itself.

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>
