4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Helge Deller <[email protected]> commit f8850abb7ba68229838014b3409460e576751c6d upstream. Architecturally we need to keep __gp below 0x1000000. But because of ftrace and tracepoint support, the RO_DATA_SECTION now gets much bigger than it was before. By moving the linkage tables before RO_DATA_SECTION we can avoid that __gp gets positioned at a too high address.
