As we know, arm64 also support gigantic hugepage eg. 1G.Well, I do not know that. How can I check?Hi Michal, Thank you for your reply. Maybe you can check the setup_hugepagesz()
OK, I see. The support was added by 084bd29810a5 ("ARM64: mm: HugeTLB
support.") in 3.11 but this got later broken. I suspect 944d9fec8d7a
("hugetlb: add support for gigantic page allocation at runtime") in
3.16 but this would require double checking. Information like this would
be really helpful in the changelog...
