[PATCH] mm, meminit: Recalculate pcpu batch and high limits after init completes -fix

[Mel Gorman]

LKP reported the following build problem from two hunks that did not
survive the reshuffling of the series reordering.

 ld: mm/page_alloc.o: in function `page_alloc_init_late':
 mm/page_alloc.c:1956: undefined reference to `zone_pcp_update'

This is a fix for the mmotm patch
mm-meminit-recalculate-pcpu-batch-and-high-limits-after-init-completes.patch
