It looks like this series hasn't been in -next at all? That seems like a
pretty important step.

Also, when I look at the PR, it seems to be a branch history going
back _years_. For this kind of a feature, I'd expect a short series of
"here's the code" in incremental additions (e.g. look at the x86 shstk
series), not the development history from it being out of tree -- this
could easily lead to ugly bisection problems, etc.
