Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

mm/vmstat.c: In function 'pagetypeinfo_showblockcount_print':
mm/vmstat.c:1230:8: warning: 'page' may be used uninitialized in this function [-Wmaybe-uninitialized]
   if (!memmap_valid_within(pfn, page, zone))
        ^

Introduced by commit

  36c7473b3c85 ("mm, vmstat: skip reporting offline pages in pagetypeinfo")

That really doesn't look good.
