1855256c49 drivers/firmware: const-ify DMI API and internals
Three main sets of changes:

1) dmi_get_system_info() return value should have been marked const,
   since callers should not be changing that data.

2) const-ify DMI internals, since DMI firmware tables should,
   whenever possible, be marked const to ensure we never ever write to
   that data area.

3) const-ify DMI API, to enable marking tables const where possible
   in low-level drivers.

And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.

The bulk of the changes are #2 and #3, which are interrelated.  #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

389679d8fa Input: wistron - add LED support
Add support to wistron_btns for leds that come with the multimedia keys.
Mail and wifi leds are supported, on laptops which have them.

Depending on the laptop, wifi subsystem may control just the led, or both
the led and the wifi card. Wifi led interface is activated only for the
former type of laptops, as the latter type is already managed. Leds are
controled by the interface in /sys/class/leds.

a4da16d383 Input: wriston - reduce polling frequency
Reduces the polling frequency from 10 Hz to 2 Hz, which should be less a burden
for laptops wrt energy saving. As it is multimedia keys, 500ms (maximum) of
latency should be still fine for the user. In order to keep fluent the feeling
when the user is pressing several keys in a raw (such as changing the volume),
the frequency is increased for a short duration after a key is pressed.

55d29c9841 Input: wistron - declare keymaps as initdata
As the number of keymaps increases and is very unlikely to
reduce, this patch helps to reduce memory consumption by
declaring all keymaps as __initdata and copying right keymap
during DMI detection. On x86 this make the module size at
runtime going from 10616 to 9428: a bit more than 1kb saved.

7b0a4cd760 Input: wistron - introduce generic keymap
It turns out that the keymaps in the wistron driver are almost the
same, the main difference being some keys which may not exist and
leds which might not be present. Therefore it's possible to write
a generic keymap which would allow the use of an unknown keyboard
with little drawbacks. The user can select it specifying the parameter
"keymap=generic".

6480e2a275 Input: wistron - add acerhk laptop database
Acerhk supports already a lot of laptops. Lets import its database so
that everyone can benefit of the work of Olaf Tauber. Only the "tm_new"
laptops were imported. "tm_old" laptops could be possible but requires
more testing and probably only few laptops are still alive. "dritek"
laptops should probably be imported into a different driver. Also compress
the keymaps by fitting each entry on an int. Most of the dmi matching was
written based on google searches, so it's rather prone to errors. That's
why I'm asking people to confirm it works.

Support to generate switch input events was added as some laptops indicate
lid open/close through this interface.

Also fix a potential issue with some notebooks:

The current code assumes the response to bios_wifi_get_default_setting is
either 1 (disabled) or 3 (enabled), or wifi isn't supported.  The BIOS
response appears to be a bit field w/ 0x1 indicating hardware presence, 0x2
indicating actiation status, and the other 6 bits being unknown/reserved --
with the patch, these 6 bits are ignored.

5fc1468029 Input: add Wistron driver
A driver for laptop buttons using an x86 BIOS interface that is
apparently used on quite a few laptops and seems to be originating
from Wistron.

This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000
(i.e. it can detect the laptop using DMI and it contains the
keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G
(probably can't be reliably autodetected, requires a module parameter),
adding other laptops should be easy.

In addition to reporting button presses to the input layer the driver
also allows enabling/disabling the embedded wireless NIC (using the
"Wifi" button); this is done using the same BIOS interface, so it seems
only logical to keep the implementation together.  Any flexibility
possibly gained by allowing users to remap the function of the "Wifi"
button is IMHO not worth it when weighted against the necessity to run
an user-space daemon to convert button presses to wifi state changes.
