SubjectRe: [rfc] mm, hugetlb: allow hugepage allocations to excessively reclaim

It can be used as a fallback when writing to nr_hugepages and the amount
allocated did not match expectation. Again, I'll defer all of this to
Mike when he returns: he expressed his preference, I suggested an
alternative to consider, and he can make the decision to ack or nack this
patch because he has a better understanding of that expectation from users
who use hugetlb pages.
