This seems like a fine cleanup because stop_machine() disable irqs, but it
appears like there is two problems with this function already:
Re-examining this, I've realized that my previous patchset containing
"mm/page_alloc: convert zone_pcp_update() to rely on memory barriers
instead of stop_machine()"
already went through and fixed this up (the right way). So ignore this
patch.
