    sparc64: Fix NMI startup bug which also breaks perf. · b62818e5
    David S. Miller authored
    Doing NMI startup as an early initcall doesn't work because we need
    to have SMP started up by then.
    
    So we'd only NMI startup one cpu, which causes perf PMU grab to
    BUG because the nmi_active count isn't what it's supposed to be.
    
    This also points out that we don't have proper CPU up/down notifiers
    for the NMI code which will need to be fixed at some point.
