[Devel] [PATCH 6/8] remove VM_HUGETLB and VM_RESERVED from CKPT_VMA_NOT_SUPPORTED

[Nathan Lynch]

Now that the hugetlb c/r support code is in place we can remove
VM_HUGETLB from the bitmask of unsupported vma flags.

All huge pages are VM_RESERVED so a less coarse method is needed to
prevent checkpoint of other reserved pages.
