[PATCH 3/3] arm64: include: asm: atomic.h: use 'unsigned int' and 'atomic_t' instead of 'unsigned long' for atomic_clear_mask()

[gang.chen@asianux.com (Chen Gang)]

In current kernel wide source, for arm64, only s390 scsi drivers use
atomic_clear_mask(), now, s390 itself need use 'unsigned int' and
'atomic_t', so need match s390's atomic_clear_mask().
