KVMCLOCK happens to be about the easiest to implement, and has a decent performance win for many situations.

I’m seeing the exact same issue. It began for me at r277472 and is
still persisting as of r277482 ( the most recent HEAD as of writing
this email ).
Well, the problem is reported several times during compilation.
This is the first warning that also has -Werror, and hence building stops.
I have not been able to find where this -Werror all of a sudden pops up.
Has to be in any of those commits...
It’s a mismatch in the macro definitions, made in the commit below.
I’m testing out a fix for it right now.
Thanks for the report!
