[PATCH] oprofile: Fix unnecessary cleverness
nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on model->num_counters (number of performance counters) being less than 10. While this is currently the case, it's too clever by half. Other archs aren't quite as clever: they assume 100. I suggest to normalize them all to 1000.
