s390/cpum_sf: Remove unused defines REG_NONE and REG_OVERFLOW
Member hw_perf_event::reg.reg is set but never used, so remove it. Defines REG_NONE and REG_OVERFLOW are not referenced anymore. The initialization to zero takes place in function perf_event_alloc() where ... event = kmem_cache_alloc_node(perf_event_cache, GFP_KERNEL | __GFP_ZERO, node); ... makes sure memory allocated for the event is zero'ed. This is done in the kernel's common code in kernel/events/core.c The struct perf_event contains member hw_perf_event as in struct perf_event { .... struct hw_perf_event hw; .... }; This contained sub-structure is also initialized to zero. No functional change.
