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!
Aslan Bakirov (1): mm: cma: NUMA node interface
Roman Gushchin (1): mm: hugetlb: optionally allocate gigantic hugepages using cma
