asus_acpi only support old models, it has been deprecated since
2009 in favor of asus-laptop, it's not built by any (sane) distro,
so it is time to say good bye.
Thanks to Julien Lerouge and Karol Kozimor for the work they have
done on it, I would never have wrote asus-laptop and other asus
related drivers without asus_acpi.

Let the user tells if BLED and WLED should be exposed as led or
rfkill (the old sysfs are still here, but this adds a standard
interface to control the device).
For example on my A6JC, with WAPF=1, I would do:
$ modprobe asus-laptop wled_type=led bluetooth_type=rfkill
There is still no known way to automatically guess what BLED
and WLED methods will control, it's why user information is needed.
A userspace database could do that automatically, and maybe some DMI
matching in the driver.

This enable the driver for everything that look like
a laptop and is from vendor "SAMSUNG ELECTRONICS CO., LTD.".
Note that laptop supported by samsung-q10 seem to have a different
vendor strict.
Also remove every log output until we know that we have a SABI interface
(except if the driver is forced to load, or debug is enabled).
Keeping a whitelist of laptop with a model granularity is something that can't
work without close vendor cooperation (and we don't have that).

Fix scancodes returned by driver to match scancodes used to remap keys.
(Before the patch FN/E returned scancode 0x1B, but to remap scancode
0x14 had to be used).
The scancodes returned by the sony-laptop driver for function keys did not
match the scancodes used to remap keys. Also, since the scancode was sent
to the input subsystem after the mapped keysym the /lib/udev/keymap
utility was confused about which scancode to report for which keysym.
This patch fixes the driver so the correct scancode is shown for each
key. It also adds to the documentation a description of where to find
the scancodes.

When the keyboard backlight support was originally added, the commit said
to default it to on with a 10 second timeout. That actually wasn't the
case, as the default value is commented out for the kbd_backlight parameter.
Because it is a static variable, it gets set to 0 by default without some
other form of initialization.
However, it seems the function to set the value wasn't actually called
immediately, so whatever state the keyboard was in initially would remain.
Then commit df410d5224 was introduced during the 2.6.39 timeframe to
immediately set whatever value was present (as well as attempt to
restore/reset the state on module removal or resume). That seems to have
now forced the light off immediately when the module is loaded unless
the option kbd_backlight=1 is specified.
Let's enable it by default again (for the first time). This should solve

This provides unified readq()/writeq() helper functions for 32-bit
drivers.
For some cases, readq/writeq without atomicity is harmful, and order of
io access has to be specified explicitly. So in this patch, new two
header files which contain non-atomic readq/writeq are added.
- <asm-generic/io-64-nonatomic-lo-hi.h> provides non-atomic readq/
writeq with the order of lower address -> higher address
- <asm-generic/io-64-nonatomic-hi-lo.h> provides non-atomic readq/
writeq with reversed order
This allows us to remove some readq()s that were added drivers when the
default non-atomic ones were removed in commit dbee8a0aff ("x86:
remove 32-bit versions of readq()/writeq()")
The drivers which need readq/writeq but can do with the non-atomic ones
must add the line:
#include <asm-generic/io-64-nonatomic-lo-hi.h> /* or hi-lo.h */
But this will be nop in 64-bit environments, and no other #ifdefs are
required. So I believe that this patch can solve the problem of
1. driver-specific readq/writeq
2. atomicity and order of io access
This patch is tested with building allyesconfig and allmodconfig as
ARCH=x86 and ARCH=i386 on top of tip/master.
