MIPS: tlb-r4k: Add missing HTW stop/start sequences HTW needs to stop and start again whenever the EntryHI register changes otherwise an inflight HTW operation might use the new EntryHI register for updating an old entry and that could lead to crashes or even a machine check exception. We fix this by ensuring the HTW has stop whenever the EntryHI register is about to change Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: <stable@vger.kernel.org> # v3.17+ Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/8511/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
