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

[Serge E. Hallyn]

Quoting Nathan Lynch (ntl at pobox.com):
> 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.
