cma_bitmap_maxno() was marked as static and not static inline, which can cause warnings about this function not being used if this file is included in a file that does not call that function, and violates the conventions used elsewhere. The two options are to move the function implementation back to mm/cma.c or make it inline here, and it's simple enough for the latter to make sense.
