functions
Several functions in the sh_mobile_ceu_camera driver implement generic
algorithms and can be re-used by other V4L2 camera host drivers too. These
functions attempt to optimise scaling and cropping functions of the
subdevice, e.g. a camera sensor. This patch makes those functions generic
for future re-use by other camera host drivers.

For CRC enabled filesystems, add support for the monotonic inode
version change counter that is needed by protocols like NFSv4 for
determining if the inode has changed in any way at all between two
unrelated operations on the inode.
This bumps the change count the first time an inode is dirtied in a
transaction. Since all modifications to the inode are logged, this
will catch all changes that are made to the inode, including
timestamp updates that occur during data writes.

... because the "clock_event_device framework" already accounts for idle
time through the "event_handler" function pointer in
xen_timer_interrupt().
The patch is intended as the completion of [1]. It should fix the double
idle times seen in PV guests' /proc/stat [2]. It should be orthogonal to
stolen time accounting (the removed code seems to be isolated).
The approach may be completely misguided.

[2] http://lists.xensource.com/archives/html/xen-devel/2010-08/msg01068.html
John took the time to retest this patch on top of v3.10 and reported:
"idle time is correctly incremented for pv and hvm for the normal
case, nohz=off and nohz=idle." so lets put this patch in.

This fixes the problem that "init=" options may not be passed to kernel
correctly.
parse_mem_cmdline() of mn10300 arch gets rid of "mem=" string from
redboot_command_line. Then init_setup() parses the "init=" options from
static_command_line, which is a copy of redboot_command_line, and keeps
the pointer to the init options in execute_command variable.
Since the commit 026cee0 upstream (params: <level>_initcall-like kernel
parameters), static_command_line becomes overwritten by saved_command_line at
do_initcall_level(). Notice that saved_command_line is a command line
which includes "mem=" string.
As a result, execute_command may point to weird string by the length of
"mem=" parameter.
I noticed this problem when using the command line like this:
mem=128M console=ttyS0,115200 init=/bin/sh
Here is the processing flow of command line parameters.
start_kernel()
setup_arch(&command_line)
parse_mem_cmdline(cmdline_p)
* strcpy(boot_command_line, redboot_command_line);
* Remove "mem=xxx" from redboot_command_line.
* *cmdline_p = redboot_command_line;
setup_command_line(command_line) <-- command_line is redboot_command_line
* strcpy(saved_command_line, boot_command_line)
* strcpy(static_command_line, command_line)
parse_early_param()
strlcpy(tmp_cmdline, boot_command_line, COMMAND_LINE_SIZE);
parse_early_options(tmp_cmdline);
parse_args("early options", cmdline, NULL, 0, 0, 0, do_early_param);
parse_args("Booting ..", static_command_line, ...);
init_setup() <-- save the pointer in execute_command
rest_init()
kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND);
At this point, execute_command points to "/bin/sh" string.
kernel_init()
kernel_init_freeable()
do_basic_setup()
do_initcalls()
do_initcall_level()
(*) strcpy(static_command_line, saved_command_line);
Here, execute_command gets to point to "200" string !!

Coalesce formats and add missing word spaces

Code in blkdev.c moves a device inode to default_backing_dev_info when
the last reference to the device is put and moves the device inode back
to its bdi when the first reference is acquired. This includes moving to
wb.b_dirty list if the device inode is dirty. The code however doesn't
setup timer to wake corresponding flusher thread and while wb.b_dirty
list is non-empty __mark_inode_dirty() will not set it up either. Thus
periodic writeback is effectively disabled until a sync(2) call which can
lead to unexpected data loss in case of crash or power failure.
Fix the problem by setting up a timer for periodic writeback in case we
add the first dirty inode to wb.b_dirty list in bdev_inode_switch_bdi().

Because calling intel_dp_encoder_destroy inside
intel_edp_init_connector is just wrong. This is the initialization
path, so we should properly unwind all the initialization through the
whole caller stack.
On the intel_dp_encoder_destroy function we do the following:
1 - Call i2c_del_adapter
2 - Call drm_encoder_cleanup
3 - If edp:
3.1 - Cancel panel_vdd_work
3.2 - Call ironlake_panel_vdd_of_sync
4 - Free the encoder
And here is how we unwind each specific step:
1 - We have intel_dp_init_connector -> intel_dp_i2c_init ->
i2c_dp_aux_add_bus -> i2c_add_adapter, so we call
i2c_del_dapter at intel_dp_init_connector
2 - Call it in the same function that called drm_encoder_init
3 - Call it in the same function that called INIT_DELAYED_WORK
4 - Free it in the same function that allocated it

By the time we call intel_dp_destroy (which destroys the connector)
the encoder may have been destroyed already, so if we use it we may be
reading some free memory. That happens in drm_mode_config_cleanup()
and also inside intel_dp_init_connector() when we detect a ghost eDP.
I also hope this may solve some random memory bugs.

This patch adds exynos_drm_crtc_mode_set_commit function
to update mode data and it makes page flip call this function
instead of calling exynos_drm_crtc_mode_set_base function directly.
exynos_drm_crtc_mode_set_base function is called by drm subsystem
as a callback so we don't have to call this function directly.
