Hi Michael,

Is there any chance we get this series pushed in 4.7 ?

Thanks,
Laurent.

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
