[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.
