If anyone has any objections, please let me know. ------------------ From: Peter Zijlstra commit 3e46e0f5ee3643a1239be9046c7ba6c66ca2b329 upstream. Since uv_flush_tlb_others() implements flush_tlb_others() which is about flushing user mappings, we should use __flush_tlb_single(), which too is about flushing user mappings.
