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.
