From: Huang Ying <ying.hu...@intel.com>
It's unreasonable to optimize swapping for THP without basic swapping
support. And this will cause build errors when THP_SWAP functions are
defined in swapfile.c and called elsewhere.
The comments are fixed too to reflect the latest progress.

Swap transparent huge pages in one piece, without splitting.

For selection by architectures with reasonable THP sizes.
