3.16.81-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Rajmal Menariya <rajmal.menariya@xxxxxxxxxxxxxx>
commit 1328d8efef17d5e16bd6e9cfe59130a833674534 upstream.
In carveout heap, change minimum allocation order from 12 to
PAGE_SHIFT. After this change each bit in bitmap (genalloc -
General purpose special memory pool) represents one page size
memory.
