So I posted one earlier today: https://lkml.kernel.org/r/[email protected] it's about a 1/3rd the number of lines and has 32bit support. It also provides all the bits required to implement static_call(). That is; I think I'm firmly in favour of the entry variant -- provided it actually works of course.
