Hi Folks,

This is a backport for PSI feature from: http://git.cmpxchg.org/cgit.cgi/linux-psi.git/log/?h=psi-4.17

The patches are included since 4.20.

We're run LTP tests and stress test with these patches on 4.14.93, no problem found.

I send them out for review, also maybe there are other guys are intereseted.

I kept the conflict note in commit message, so it's easier to review.

This is nice, but why? We can't take new features into the stable kernel trees. For Android devices (which do want PSI), all of the patches are already backported into the android-common 4.14 branch, right? Or does this differ from that backport somehow?

thanks,
