bb7ca747f8 backlight: add backlight type
There may be multiple ways of controlling the backlight on a given
machine.  Allow drivers to expose the type of interface they are
providing, making it possible for userspace to make appropriate policy
decisions.

ba1ff5be52 asus-laptop: add wimax and wwan support
Asus UL30A has a 3G chip, but the radio is disabled by default.
The DSDT also reference a WIMAX device, which is not present on this model.

This patch adds two new files: wwan and wimax to control WWAN and
WIMAX devices. It does not use rfkill, because like WLED and BLED,
we don't know yet that the two ACPI functions will always control the
radio, they may control only the leds on some hardware.

We may add rfkill switchs later.

acc2472ed3 backlight: constify backlight_ops
backlight_device_register has been expecting a const "ops" argument, and using
it as such, since 9905a43b2d. Let's make the
remaining backlight_ops instances const.

Inspired by hunks of the grsecurity patch, updated for newer kernels.

c26d85cb90 asus-laptop: fix wapf, wlan_status and bluetooth_status module_param permissions
The wapf module parameters defines the behavior of the Fn+Fx wlan key.
The wlan_status and bluetooth_status module parameters are for setting the
wlan/bluetooth status on boot.

All above module parameters are determinated only at the module load time.
 Change the value after the module is loaded does not make sense and has
no effect at all, thus set the permissions to 0444 instead of 0644.

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

9129d14d29 asus-laptop: callbacks should use "driver data" parameter or field
(Changelog stolen from Alan's patch for eeepc-laptop, but this patch
does the same thing for asus-laptop)

Callback methods should not refer to a variable like "asus" (formally
"hotk").  Instead, they should extract the data they need either from
a "driver data" parameter, or the "driver data" field of the object
which they operate on.  The "asus" variable can then be removed.

In practice, drivers under "drivers/platform" can get away without using
driver data, because it doesn't make sense to have more than one
instance of them.  However this makes it harder to review them for
correctness.  This is especially true for core ACPI developers who have
not previously been exposed to this anti-pattern :-).

This will serve as an example of best practice for new driver writers
(whether they find it themselves, or have it pointed out during review
:-).

 - Battery Status (Fn+F3)
 - WLAN switch (Fn+F5)
 - Video output switch (Fn+F7)
 - Touchpad switch (Fn+F8)
