There is a small bug in the handling of 16G hugepages recently added to the kernel. This doesn't cause a crash or other user-visible problems, but it does mean that more levels of pagetable are allocated than makes sense for 16G pages. The hugepage pagetables for the 16G pages are allocated much lower in the pagetable tree than they should be, with the intervening levels allocated with full pmd and pud pages which will only ever have one entry filled in. This corrects this problem, at the same time cleaning up the handling of which level 64k versus 16M hugepage pagetables are allocated at. The new way of formatting the tests should be more robust against changes in pagetable structure, or any newly added hugepage sizes.
