NULL, if there is no lcd or it is not enabled in configuration.

The LCD controller (EPSON S1D13744) supports rotation (0, 90, 180 and 270
degrees) on hardware just setting the bits 0 and 1 of 0x28 register (LCD
Panel Configuration Register). Now it is possible to use this caps only
setting the angle degree on var rotate of fb_var_screeninfo using the
FBIOPUT_VSCREENINFO ioctl.

Add a mutex to avoid a circular locking problem between the mm layer
semaphore and fbdev ioctl mutex through the fb_mmap() call.
Also, add mutex to all places where smem_start and smem_len fields change
so the mutex inside the fb_mmap() is actually used. Changing of these
fields before calling the framebuffer_register() are not mutexed.
This is 2.6.31 material. It removes one lockdep (fb_mmap() and
register_framebuffer()) but there is still another one (fb_release() and
register_framebuffer()). It also cleans up handling of the smem_start and
smem_len fields used by mutexed section of the fb_mmap().

This patch fixes a number of sillies, from missing 'const' to using
'return' in void functions, to functions with no arguments not even
'void' and a cast which isn't required.

There are 43 includes of asm/mach-types.h by files that don't
reference anything from that file. Remove these unnecessary
includes.

On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
boundary. For example:
u64 val = PAGE_ALIGN(size);
always returns a value < 4GB even if size is greater than 4GB.
The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
example):
#define PAGE_SHIFT 12
#define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT)
#define PAGE_MASK (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK)
The "~" is performed on a 32-bit value, so everything in "and" with
PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
Using the ALIGN() macro seems to be the right way, because it uses
typeof(addr) for the mask.
Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
include/linux/mm.h.

- Add Texas Instruments OMAP framebuffer driver. This driver is being used
for various OMAP1/2 series based boards and products e.g Nokia N800 Internet
Tablet, H4, H3, Siemens SX1 etc.
- LCD panel registration and controller code is separated in different file
and interfaces.
