Unfortunately, the harkernel tree git repo doesn't help understand where the change came from because an entire v3.10.y based Samsung BSP is checked into the tree on top of a v3.8.y kernel in a single commit !!! Abhilash, in the absence of the original author, could write up a patch with your change? Or, if you can help me with a detailed changelog, I can work on the patch. I don't have any exynos docs, so it would be good to have a description of what reading/writing to that register are actually doing. Also, can you explain what you meant by using exynos_core_restart? I don't see that function in mainline.
