In the buddy allocator use the actual size of the PDE to determine the pte_blk_order field which is used to determine what page size a buddy has (or doesn't). Previously this was just set as the large page size times 1024 which would over allocate PDE ranges for Pascal+ chips. This caused userspace, which was using the real PDE size, to sometime allocate small and large pages in what the buddy allocator mistakenly thought was one PDE.
