The patchset adds a hugetlb_cma boot option, which allows to reserve a cma area which can be later used for 1 GB hugepages allocations. This is v4 of the patch(set). It contains a patch from Aslan, which adds a useful function of the cma side, and the previous version of the hugetlb_cma patch (v3) with all following cleanups and fixes squashed, plus the following changes: 1) removed the hard-coded archs list from docs 2) added a warning printing on non-supported archs 3) hugetlb_lock is temporarily dropped in update_and_free_page() I've retained Michal's and Mike's acks, because changes are not significant. Please, let me know if there is something wrong. Thanks!
