Babu Moger 79d39e2bab arch/sparc: Introduce xchg16 for SPARC ... SPARC supports 32 bit and 64 bit xchg right now. Add the support for 16 bit (2 byte) xchg. This is required to support queued spinlock feature which uses 2 byte xchg. This is achieved using 4 byte cas instructions with byte manipulations. Also re-arranged the code to call __cmpxchg_u32 inside xchg16.
