3.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Huacai Chen <[email protected]> commit 8393c524a25609a30129e4a8975cf3b91f6c16a5 upstream. In commit 2c8c53e28f1 (MIPS: Optimize TLB handlers for Octeon CPUs) build_r4000_tlb_refill_handler() is modified. But it doesn't compatible with the original code in HUGETLB case. Because there is a copy & paste error and one line of code is missing. It is very easy to produce a bug with LTP's hugemmap05 test.
