Aneesh Kumar K.V bde3eb6222 powerpc/mm/radix: Add radix THP callbacks
The deposited pgtable_t is a pte fragment hence we cannot use page->lru
for linking then together. We use the first two 64 bits for pte fragment
as list_head type to link all deposited fragments together. On withdraw
we properly zero then out.
