We should start planning on a Test Day schedule.

@Stefano:
Didn't the ARM KCONFIG stuff go in *after* 4.11? If so, this should probably be 
added. 
Can't recall the series name

Also, I think the Aggios changes went in after 4.11 was released also.
The series was "xen/arm64: Suspend preconditions and CPU hotplug fixes"

@ALL: also, for any major new features and/or enablers, we should look at the 
docs and make sure they are in place and up-to-date, that SUPPORT.md is updated 
and that any worthy/big enough features are listed. Also, if you contributed a 
larger series/feature and it is not on this list, please let us know.  

Thank you to everyone contributing to the project

Best Regards
Lars
