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.
