 Why:	setitimer is not returning -EFAULT if user pointer is NULL. This
 	violates the spec.
 Who:	Sasikantha Babu <sasikanth.v19@gmail.com>
+
+----------------------------
+
+What:	V4L2_CID_HCENTER, V4L2_CID_VCENTER V4L2 controls
+When:	3.7
+Why:	The V4L2_CID_VCENTER, V4L2_CID_HCENTER controls have been deprecated
+	for about 4 years and they are not used by any mainline driver.
+	There are newer controls (V4L2_CID_PAN*, V4L2_CID_TILT*) that provide
+	similar	functionality.

+ * This funciton is cloned from arch/arm/mach-tegra/headsmp.S, and needs
