sparc64: Provide cmpxchg64()
sparc64 allmodconfig: drivers/block/blockconsole.c: In function ‘bcon_advance_console_bytes’: drivers/block/blockconsole.c:164: error: implicit declaration of function ‘cmpxchg64’ Map cmpxchg64() to cmpxchg64_local() (which eventually calls __cmpxchg_u64()) to fix this.
