We're working on investments for LDCG[0] in 2019 that include kernel CI
changes for server use cases. Please keep us informed of what you folks
ultimately want to see, and I'll pass on to the steering committee too.

Ultimately I've been pushing for a kernel 0-day project for Arm. That's
probably going to require a lot of duplicated effort since the original
0-day project isn't open, but creating an open one could help everyone.
