Am-I-affected-by-Meltdown: Your cpu doesn't support TSX (Transactional Synchronization Extensions)

When getting the message above, does this mean that the CPU isn’t affected or that Am-I-affected-by-Meltdown not able to check? I presume the latter from the note in README.md, but I figured I’d better check.

The latter. I’ll improve the checker to work without TSX

What is a modern CPU? Because I have a Intel(R) Core(TM) i7-4510U CPU and I have this error.
