e04e39507c drivers/video/fbdev: use ioremap_wc/wt() instead of __ioremap()
_PAGE_NO_CACHE is a platform specific flag. In addition, this flag
is misleading because one would think it requests a noncached page
whereas a noncached page is _PAGE_NO_CACHE | _PAGE_GUARDED

_PAGE_NO_CACHE alone means write combined noncached page, so lets
use ioremap_wc() instead.

_PAGE_WRITETHRU is also platform specific flag. Use ioremap_wt()
instead.

2d9e4e2bb5 video/chips: constify fb_fix_screeninfo and fb_var_screeninfo structures
These structures are only used to copy into other structures,
so declare them as const.

This issue was detected using Coccinelle and the following semantic patch:

@r disable optional_qualifier@
identifier i;
position p;
@@
static struct fb_fix_screeninfo i@p = { ... };

@ok@
identifier r.i;
expression e;
position p;
@@
e = i@p

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct fb_fix_screeninfo e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
 struct fb_fix_screeninfo i = { ... };

The semantic patch for fb_var_screeninfo is analogous.

754d561ab6 fbdev: Remove __init from chips_hw_init() to fix build failure
Fix build failure caused as follows:

The function chipsfb_pci_init() references
the function __init chips_hw_init().
This is often because chipsfb_pci_init lacks a __init
annotation or the annotation of chips_hw_init is wrong.

make: *** [drivers] Error 2

by removing the __init annotation from chips_hw_init(). The other thing that
could have been done was annotating chipsfb_pci_init(). But that cannot be done
since chipsfb_pci_init() is called from non __init functions.

f7018c2135 video: move fbdev to drivers/video/fbdev
The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
