That tree is no longer being updated.  Please switch to

	git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Either the mm-unstable branch (hotfixes and MM) or the mm-everything
branch (mm-unstable plus non-MM patches).

mm-unstable includes
https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-make-alloc_contig_range-work-at-pageblock-granularity-fix.patch,
which quite possibly fixes the issue you have detected.

Thanks.
