I asked Sohil to start throwing out all the non-essential bits from this
series. My thought was that we could get mainline so that LASS itself
could be enabled, even if it was in a somewhat weird config that a
distro would probably never do.

After that is merged, we can circle back and decide what to do with the
remaining bits like CR pinning and vsyscall emulation. I don't think any
of those bits will change the basic desire to have LASS support in the
kernel.

Does that sound like a sane approach to everyone?
