On systems where CPUs may run asynchronously, task migrations
between CPUs running at grossly different speeds can cause
problems.
This change provides a mechanism to notify a subsystem
in the kernel if a task in a particular cgroup migrates to a
different CPU. Other subsystems (such as cpufreq) may then
register for this notifier to take appropriate action when
such a task is migrated.
The cgroup attribute to set for this behavior is
"notify_on_migrate" .

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.

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.
