commit b3b33d3c43bbe0177d70653f4e889c78cc37f097 upstream.
Variable populated, which is a member of struct pcpu_chunk, is used as a
unit of size of unsigned long.
However, size of populated is miscounted. So, I fix this minor part.
Fixes: 8ab16c43ea79 ("percpu: change the number of pages marked in the
first_chunk pop bitmap")
