[PATCH] mm-cma-add-functions-to-get-region-pages-counters-fix-3

[Dmitry Safonov <d.safonov@partner.samsung.com>]

Fix for the next compiler warnings:
mm/cma_debug.c:45 cma_used_get() warn: should 'used << cma->order_per_bit' be a 64 bit type?
mm/cma_debug.c:67 cma_maxchunk_get() warn: should 'maxchunk << cma->order_per_bit' be a 64 bit type?
