Hi,
I haven't seen much comments on the static key based version from Mark so I don't know which direction we'll eventually take. I still hope we can focus on a unified static call based implementation, considering there are other users waiting on arm64 static calls.
So here is a rebase against the latest tip:sched/core and arm64 static call proposal.
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git preempt/arm-v4
HEAD: 6fc1c7e3d83c4e06b019b041894d9bb25f37ac6c
Thanks, Frederic ---

Ard Biesheuvel (2): static_call: Use non-function types to refer to the trampolines arm64: implement support for static call trampolines
