- * Functions that deal with pagetables that could be at any level of
10
- * the table need to be passed an "index_size" so they know how to
11
- * handle allocation.  For PTE pages (which are linked to a struct
12
- * page for now, and drawn from the main get_free_pages() pool), the
13
- * allocation size will be (2^index_size * sizeof(pointer)) and
14
- * allocations are drawn from the kmem_cache in PGT_CACHE(index_size).
15
- *
16
- * The maximum index size needs to be big enough to allow any
17
- * pagetable sizes we need, but small enough to fit in the low bits of
18
- * any page table pointer.  In other words all pagetables, even tiny
19
- * ones, must be aligned to allow at least enough low 0 bits to
20
- * contain this value.  This value is also used as a mask, so it must
21
- * be one less than a power of two.
