I've been asking who needs ARM support and nobody spoke up. Arnd then picked up some of the patches and for v6.13 the ARM queue got smaller. Looking at what affects ARM from the queue there is just the ktimer thread and the ARM specific bits.

The last patch > published was 6.12-rc4-rt6 from october. v6.12 is a LTS. And I wanted to add some PowerPC bits because it does not boot on some parts as I've been told. What about I make a release for the current stable tree and then update it once the patches no longer apply on a newer stable tree? > Greets > Alex Sebastian
