What about the following new element under <hugepages/> ?
enforce_hugepage_size=integer
Which feels a bit redundant (we're already under the <hugepages>
element, after all). Maybe:
<hugepages>
<size strict='yes' unit='G'>1</size>
</hugepages>
where strict could be no if we are giving a hint but don't care if the
hint cannot be honored (default yes if omitted), and where unit + value
allows the user to input the size in a sensible unit (on output, we'd
probably want to use unit='k' and spell out 1048576, for similarity with
all our other memory interfaces that output in k for back-compat reasons).
