Check for NPT enabled on Arch Linux

Hi there!

Now this might be a dumb question but, I was going through this article from Wendell about patching NPT on Linux for Better VM Guest performance with Hardware passthrough. [https://level1techs.com/article/patch-npt-ryzen-better-performance]

Now i honestly dont know how to check if NPT is even enabled on my system. How do i do that? How do i force it on?
