Paul Burton d15dc68c11 MIPS: cmpxchg: Error out on unsupported xchg() calls ... xchg() has up until now simply returned the x parameter in cases where it is called with a pointer to a value of an unsupported size. This will often cause the calling code to hit a failure path, presuming that the value of x differs from the content of the memory pointed at by ptr, but we can do better by producing a compile-time or link-time error such that unsupported calls to xchg() are detectable earlier than runtime. This patch does this in the same was as is already done for cmpxchg(), using a call to a missing function annotated with __compiletime_error().
