Subject: [PATCH] mm: cma: mark cma_bitmap_maxno() inline in header

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.
