Subject[PATCH v5 0/2] mm: using CMA for 1 GB hugepages allocation
Date
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.

v5:
1) made the hugetlb_cma work if a cma reservation fails on some nodes

v4:
1) added a patch from Aslan, which is adding a useful function to cma
2) removed the hard-coded archs list from docs
3) added a warning printing on non-supported archs
4) hugetlb_lock is temporarily dropped in update_and_free_page()

Thanks!
