I applied the v8 to an immutable branch and pushed to kernelorg so the build servers can churn it a bit, and if it works fine then we can merge this into the devel branch and also set up that as something other subsystems can pull in if they need it. I'm really excited to merge this! Yours, Linus Walleij
