Thanks Peter. What's an ETA on landing endbr set?
Did I miss a pull req?
I see an odd error in linux-next with bpf selftests
which may or may not be related. Planning to debug it
when everything settles in Linus's tree.

Masami, could you do another respin?

Also do you mind squashing patches 2,3,4 ?
It's odd to have the same lines of code patched up 3 times.
Just do it right once.
