Makes use of skip_spaces() defined in lib/string.c for removing leading
spaces from strings all over the tree.
It decreases lib.a code size by 47 bytes and reuses the function tree-wide:
text data bss dec hex filename
64688 584 592 65864 10148 (TOTALS-BEFORE)
64641 584 592 65817 10119 (TOTALS-AFTER)
Also, while at it, if we see (*str && isspace(*str)), we can be sure to
remove the first condition (*str) as the second one (isspace(*str)) also
evaluates to 0 whenever *str == 0, making it redundant. In other words,
"a char equals zero is never a space".

VRFB rotation engine is a block in OMAP2/3 that offers 12 independent
contexts that can be used for framebuffer rotation.
Each context has a backend area of real memory, where it stores the
pixels in undisclosed format. This memory is offered to users via 4
virtual memory areas, which see the same memory area in different
rotation angles (0, 90, 180 and 270 degrees).

manager has that are missing from dma_alloc_* functions are:
- Support for OMAP2's SRAM
- Allocate without ioremapping
- Allocate at defined physical addresses
- Allows larger VRAM area and larger allocations
The upcoming DSS2 uses VRAM manager.
VRAM area size can be defined in kernel config, board file or with
kernel boot parameters. Board file definition overrides kernel config,
and boot parameter overrides kernel config and board file.

In Xen-paravirt mode, VM_IO flag signifies that the page frame number (PFN)
is actually a machine frame number (MFN). This is correct for memory backed by
PCI devices, but wrong for memory allocated from System RAM where the PFN
!= MFN.
During page faults, pages with VM_IO, get assigned to special domain I/O
domain and as said, the PFN is interpreted as MFN. When Xen hypervisor
modifies the PTE it interprets the PFN as the MFN, complains and
fails the PTE modification.
The end result is an infinitive page fault in the domain.

attention to the 'var' parameter passed in, and Ville Syrjälä pointed
out, this is potentially dangerous as user could pass in any other

Remove fb_save_state() and fb_restore_state operations from frame buffer layer.
They are used only in two drivers:
1. savagefb - and cause bug #11248
2. uvesafb
Usage of these operations is misunderstood in both drivers so kill these
operations, fix the bug #11248 and avoid confusion in the future.
Tested on Savage 3D/MV card and the patch fixes the bug #11248.
The frame buffer layer uses these funtions during switch between graphics
and text mode of the console, but these drivers saves state before
switching of the frame buffer (in the fb_open) and after releasing it (in
the fb_release). This defeats the purpose of these operations.

More aggressive DMA mapping debugging has uncovered a long-standing
buglet in the way that the sh_mobile_lcdcfb driver implements its
deferred I/O callback. When used as a console driver the acceleration
routines are called by the kernel which subsequently cause the deferred
I/O work to be scheduled, resulting in the deferred I/O callback being
entered without any dirty pages on the pagelist (the normal case for
userspace accesses). It's also possible to get in to this situation via
explicit calling of fsync() when nothing has dirtied the region.
Unfortunately it's not sufficient to skip over the callback when the
pagelist is empty given the console driver use case, so instead the
callback has to conditionalize the work for panel updates and DMA
mapping depending on whether anything is resident on the pagelist or
not.

Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.
This was done with:
#!/bin/bash
mach_dir_old="arch/arm/plat-omap/include/mach"
plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)
omap_dirs="arch/arm/*omap*/ \
drivers/video/omap \
sound/soc/omap"
other_files="drivers/leds/leds-ams-delta.c \
drivers/mfd/menelaus.c \
drivers/mfd/twl4030-core.c \
drivers/mtd/nand/ams-delta.c"
for header in $headers; do
old="#include <mach\/$header"
new="#include <plat\/$header"
for dir in $omap_dirs; do
find $dir -type f -name \*.[chS] | \
xargs sed -i "s/$old/$new/"
done
find drivers/ -type f -name \*omap*.[chS] | \
xargs sed -i "s/$old/$new/"
for file in $other_files; do
sed -i "s/$old/$new/" $file
done
done
for header in $(ls $mach_dir_old/*.h); do
git mv $header $plat_dir_new/
done

This fixes a bug introduced by this commit ID:

fbdev: add mutex for fb_mmap locking
In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.
The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.
Solution: Don't use mutex before framebuffer registration.
