Hi Jiri,

Sorry about this; I've been a bit distracted.

I've just done the core (non-arm64) bits today, and pushed that out:

https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/log/?h=arm64/ftrace-with-regs

... I'll fold the remainging bits of patches 4 and 5 together tomorrow
atop of that.

Thanks,
Mark.
