For image statatistics for concurrent ISP, we
collect statistics for a single camera sensor from
two ISP hardware. A single buffer is passed from userspace
and share between two ISP hardware using different buffer
offset. When both hardware are done with the buffer,
a stats done event will be send to userspace.

There can be SoCs which have different amount of VFEs connected to
ISPIF, while the CSID version is kept the same. For such cases there is
a need to have additional information about the number of VFEs connected
to each ISPIF interface, and its capabilities.
As there is no way for the ISPIF to guess this information on its own,
this change introduces a new ISPIF ioctl cmd, called ISPIF_SET_VFE_INFO.
This command will store the information for the number of VFEs connected
and also VFEs capabilities.
The above information is used where number of VFEs information is
required. Such places are vfe clock request, ISPIF irq handling and
others.

For concurrent ISP operation, a single camera image is
split and feed into two ISP. Each ISP will process
the image independently and output to different location in
one single buffer. This change add support to synchronize
the buffer used in each ISP. When the first ISP dequeue
a buffer, the buffer will be store in a separate queue.
The second ISP will first check the intermediate queue
and then check the main queue for buffer. When ISP is done
processing the image, the buffer will be send out only
when both ISPs are done with the buffer.

This patch corrects a buffer overflow in kernels from 3.0 to 3.4 when calling
log_prefix() function from call_console_drivers().
This bug existed in previous releases but has been revealed with commit
162a7e7500 (2.6.39 => 3.0) that made changes
about how to allocate memory for early printk buffer (use of memblock_alloc).
It disappears with commit 7ff9554bb578ba02166071d2d487b7fc7d860d62 (3.4 => 3.5)
that does a refactoring of printk buffer management.
In log_prefix(), the access to "p[0]", "p[1]", "p[2]" or
"simple_strtoul(&p[1], &endp, 10)" may cause a buffer overflow as this
function is called from call_console_drivers by passing "&LOG_BUF(cur_index)"
where the index must be masked to do not exceed the buffer's boundary.
The trick is to prepare in call_console_drivers() a buffer with the necessary
data (PRI field of syslog message) to be safely evaluated in log_prefix().
This patch can be applied to stable kernel branches 3.0.y, 3.2.y and 3.4.y.
Without this patch, one can freeze a server running this loop from shell :
$ export DUMMY=`cat /dev/urandom | tr -dc '12345AZERTYUIOPQSDFGHJKLMWXCVBNazertyuiopqsdfghjklmwxcvbn' | head -c255`
$ while true do ; echo $DUMMY > /dev/kmsg ; done
The "server freeze" depends on where memblock_alloc does allocate printk buffer :
if the buffer overflow is inside another kernel allocation the problem may not
be revealed, else the server may hangs up.

(1) ISP interface(ISPIF) sits between sensor(CSID) and ISP.
It's responsible to mux sensor's output path to
ISP input path. ISPIF driver contains two parts, i.e.,
user space driver and kernel driver. The kernel driver is
mainly for register write and read.
(2) Image signal processing(ISP) driver's responsiblity is to
processed the sensor's raw image to generate the YUV image
for rending/video encoding and snapshot. ISP driver has
following main functional blcoks:
- Image bus(AXI) management and configuration
- ISP processing pipeline configuration and run time update
- ISP input interface(CAMIF) configuration
- Image buffer management
- ISP interrupt handling
- ISP kernel event notification to user space
- ISP hardware start/stop state machine.
