Build failures in -next due to 'locking/atomic, arch/arc: Implement atomic_fetch_{add,sub,and,andnot,or,xor}()'

Hi Peter,

I am seeing build failures in -next when trying to build arc / arcv2 targets.

arch/arc/include/asm/atomic.h:74:2: error: ‘SCOND_FAIL_RETRY_VAR_DEF’ undeclared
arch/arc/include/asm/atomic.h:87:2: error: expected ‘:’ or ‘)’ before 
‘SCOND_FAIL_RETRY_ASM’

Problems seem to be caused by 'locking/atomic, arch/arc: Implement
atomic_fetch_{add,sub,and,andnot,or,xor}()'. Both SCOND_FAIL_RETRY_VAR_DEF and
SCOND_FAIL_RETRY_ASM are undefined.
