Indeed, it has been a while.

I've been quite busy lately, but expect the v8 of the LL/SC patch
series by the end of this week. Sorry for the delay.
In any case, I'm in if any call will be held.

Well it mostly seemed to be me talking but here are my notes:
- LL/SC Patch Status (Alvise)
- v8 will be posted this week, follow-up MTTCG due
- will require async_safe_work
- AJB will post his revised re-based safe work series
- Linaro's approach going forward (Alex)
- Take the uncontroversial clean-ups, push the upstream (mostly Sergey)
- Provide a common set of base patches (enables MTTCG but not arch support)
- (ADDED) Deferred work patches, needed separately for LL/SC MTTCG work
- Following up with individual architecture enabling series (ARMv7, v8, onwards)
- Memory ordering work (Alex)
- Several applicants to proposed GSoC project
- Will move forward once Google confirm funding
- Emilio's work
- Emilio is back working on MTTCG, based on common base-patches
- Others have seen his QHT proposals, review feedback from TCG devs looks good
- TCG Maintainers view
- Not had much feedback on later series, Alex will reach out
- Timescales
- Linaro is committed to having all major work on list by KVM Forum 2016
- Hopefully by KVM Forum we can work on roadmap to merging
- Alex will be there, too early for most of the others to confirm
- Any other business
- Mark commented it was nice to see things moving forward again ;-)

Thanks Alex,
sorry I was so ‘mute’ - seems I have gremlins on the phone line again!
Cheers
Good to see Sergey on, I’ve added him to the list
Mark.
