From: Peter Xu <peterx@redhat.com> It is a preparation work to be able to behave differently in the per architecture huge_pte_alloc() according to different VMA attributes. Pass it deeper into huge_pmd_share() so that we can avoid the find_vma() call.

Thanks, this will be needed for multiple features where pmd sharing must be disabled. And, the need to disable sharing is based on information in the vma. Reviewed-by: Mike Kravetz <redacted> -- Mike Kravetz
