3.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Markos Chandras <markos.chand...@imgtec.com> commit 6521d9a436a62e83ce57d6be6e5484e1098c1380 upstream. The CPS code is doing several memory loads when configuring the VPEs from secondary cores, so the segmentation control registers must be initialized in time otherwise the kernel will crash with strange TLB exceptions.
