From 4843cf8d3be4d45f609c865698b63374ae935042 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 9 Jun 2017 17:26:41 -0700 Subject: MIPS: cmpxchg: Rearrange __xchg() arguments to match xchg() The __xchg() function declares its first 2 arguments in reverse order compared to the xchg() macro, which is confusing & serves no purpose. Reorder the arguments such that __xchg() & xchg() match.
