Florian reviewed the last iteration of the patch and asked me to go
for a more declarative approach where we make the framework aware of
the data type of the tunable.  I'm doing this on my own time and I
haven't had a lot of it lately, due to which iterations of the
patchset are not coming in as regularly as they should.  I have a day
free this weekend and I hope to get a new iteration up in that time.

However if you need this feature more urgently and have a person who
can work on it then let me know and I'll help ramp him/her up and help
with reviews instead.
