Patch series v8, as discussed.
The whole series applies cleanly on 5.0-rc5

So what's the status now? Besides debatable minor style
issues there were no more objections to v8. Would this
go through the ARM repo or via the ftrace repo?

Sorry, I have some half-written review comments that I will clean up and
send shortly.

Ping?

As commented on prior versions, I'd very much like to see the
MCOUNT_ADDR hack go, by teaching the core ftrace code to not assume that
an mcount symbol exists.

We should be able to do that by separating the notion of NOPing a patch
site from the notion of initializing it for the first time.

This is generally a good idea, and would affect other architectures as well,
see arch/s390/kernel/ftrace.c ftrace_make_nop(...)

I propose to do this in a second round.

	Torsten
