Although it's probably okay, is it >actually required? Looks like the first hunk is what fixes the issue. It's probably not strictly required, but sill better than iterating over NR_CPUS, as that is what mainline is in the process of phasing out. The only difference I can see to the results of the original code is that for cpu 0 the two array members now also get (re-)initialized here - but the value stored should be the same as may have been stored earlier.
