When this patch was originally submitted, bugs were discovered in the
hugetlb_vmdelete_list routine.  So, the patch "Fix bugs in
hugetlb_vmtruncate_list" was created.

I have retested the changes in this patch specifically dealing with
page fault/hole punch race on top of the new hugetlb_vmtruncate_list
routine.  Everything looks good.

How would you like to proceed with the patch?
- Should I create a series with the hugetlb_vmtruncate_list split out?
- Should I respin with hugetlb_vmtruncate_list patch applied?

Just let me know what is easiest/best for you.
