Thomas Gleixner 2d30a1f631 mm: do not iterate over NR_CPUS in __zone_pcp_update() ... __zone_pcp_update() iterates over NR_CPUS instead of limiting the access to the possible cpus. This might result in access to uninitialized areas as the per cpu allocator only populates the per cpu memory for possible cpus. This problem was created as a result of the dynamic allocation of pagesets from percpu memory that went in during the merge window - commit 99dcc3e5a9 ("this_cpu: Page allocator conversion").
