48c68c4f1b Drivers: video: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

355b200bac video: Add module.h to drivers/video files who really use it.
They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include module.h explicitly now.

c84c14224b carminefb: Fix module parameters permissions
The third parameter of module_param is supposed to be an octal value.
The missing leading "0" causes the following:

$ ls -l /sys/module/carminefb/parameters/
total 0
-rw-rwxr-- 1 root root 4096 Jul  8 08:55 fb_displays
-rw-rwxr-- 1 root root 4096 Jul  8 08:55 fb_mode
-rw-rwxr-- 1 root root 4096 Jul  8 08:55 fb_mode_str

After fixing the perm parameter, we get the expected:

$ ls -l /sys/module/carminefb/parameters/
total 0
-r--r--r-- 1 root root 4096 Jul  8 08:56 fb_displays
-r--r--r-- 1 root root 4096 Jul  8 08:56 fb_mode
-r--r--r-- 1 root root 4096 Jul  8 08:56 fb_mode_str

e045da7d83 drivers/video/carminefb.c: improve error handling
This code had an error handling goto to the wrong place, a misplaced
release_mem_region, and a duplicated release_mem_region.

The semantic match that finds the double release_mem_region is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
expression e1,e2,e3;
position p1,p2,p3;
@@
release_mem_region@p1(e1, e2)@p3;
... when != request_mem_region(e1,e2,e3)
release_mem_region(e1, e2)@p2;

@@
expression e <= r.e1,e3;
expression r.e1,e2;
position r.p1,r.p2,r.p3,p!=r.p1;

*release_mem_region(e1, e2)@p3;

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.

313cc59eac framebuffer: fix carminefb section mismatch
Make alloc_carmine_fb() __devinit.

WARNING: drivers/video/carminefb.o(.text+0x81b): Section mismatch in reference from the function alloc_carmine_fb() to the variable .devinit.data:carminefb_fix

The function alloc_carmine_fb() references the variable __devinitdata
carminefb_fix.  This is often because alloc_carmine_fb lacks a
__devinitdata annotation or the annotation of carminefb_fix is wrong.
