Tejun Heo 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.

/* GENERAL NOTES:
*
* BUGS:
* - There are pops (we can't delay in trigger function, cause midlevel
* often need to trigger down and then up very quickly).
* Any ideas?
* - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
*/
/*
* ES1868 NOTES:
* - The chip has one half duplex pcm (with very limited full duplex support).
*
* - Duplex stereophonic sound is impossible.
* - Record and playback must share the same frequency rate.
*
* - The driver use dma2 for playback and dma1 for capture.
*/
/*
* ES1869 NOTES:
*
* - there are a first full duplex pcm and a second playback only pcm
* (incompatible with first pcm capture)
*
* - there is support for the capture volume and ESS Spatializer 3D effect.
*
* - contrarily to some pages in DS_1869.PDF the rates can be set
* independently.
*
* - Zoom Video is implemented by sharing the FM DAC, thus the user can
* have either FM playback or Video playback but not both simultaneously.
* The Video Playback Switch mixer control toggles this choice.
*
* BUGS:
*
* - There is a major trouble I noted:
*
* using both channel for playback stereo 16 bit samples at 44100 Hz
* the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
*
* The same happens using Audio1 for captureing.
*
* The Windows driver does not suffer of this (although it use Audio1
* only for captureing). I'm unable to discover why.
*
*/
/*
* ES1879 NOTES:
* - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
* seems to be effected (speaker_test plays a lower frequency). Can't find
* anything in the datasheet to account for this, so a Video Playback Switch
* control has been included to allow ZV to be enabled only when necessary.
* Then again on at least one test system the 0x71 bit 6 enable bit is not
* needed for ZV, so maybe the datasheet is entirely wrong here.
