Hi Laurent, Sorry no. My next branch closed for 4.7 about 3 weeks ago. This series has been blocked for a long time on the gdb support, but that is now working. However it still doesn't pass its own selftests, and I had some disagreements with the implementation - it duplicates a lot of code rather than refactoring things. I'm waiting on a patch from Cyril which will rework how the TM FP state is handled, and that should make this series easier to implement. The plan is that both should go into 4.8. cheers
