What's wrong with Jack's patch?

Jack's code doesn't have this limitation.  IMO it's a more sane way to
go.  Why should people be restricted to a limited set (two) of
hugepage sizes?  This seems especially important for vendor kernels
where people want to use the same kernel across a variety of different
machines.
