Hi all,

After merging the akpm-current tree, today's linux-next build (i386
defconfig) produced this warning:

mm/hugetlb.c:49:20: warning: 'hugetlb_cma' defined but not used [-Wunused-variable]
   49 | static struct cma *hugetlb_cma[MAX_NUMNODES];
      |                    ^~~~~~~~~~~

Maybe introduced by commit

  c70205bf186e ("mm/hugetlb: avoid hardcoding while checking if cma is enable")
