+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.

+ * The secondary kernel init calls v7_flush_dcache_all before it enables
+ * the L1; however, the L1 comes out of reset in an undefined state, so
+ * the clean + invalidate performed by v7_flush_dcache_all causes a bunch
+ * of cache lines with uninitialized data and uninitialized tags to get
+ * written out to memory, which does really unpleasant things to the main
+ * processor.  We fix this by performing an invalidate, rather than a
+ * clean + invalidate, before jumping into the kernel.
+ *
+ * This funciton is cloned from arch/arm/mach-tegra/headsmp.S, and needs
+ * to be called for both secondary cores startup and primary core resume
+ * procedures.  Ideally, it should be moved into arch/arm/mm/cache-v7.S.
