* Functions that deal with pagetables that could be at any level of

* handle allocation. For PTE pages, the allocation size will be
* (2^index_size * sizeof(pointer)) and allocations are drawn from
* the kmem_cache in PGT_CACHE(index_size).
*
* The maximum index size needs to be big enough to allow any
* pagetable sizes we need, but small enough to fit in the low bits of
* any page table pointer. In other words all pagetables, even tiny
* ones, must be aligned to allow at least enough low 0 bits to
* contain this value. This value is also used as a mask, so it must
* be one less than a power of two.
