The first patch is already reviewed. v2 update: So I've tried to see how to put the dom0less code in the common code, but the amount of modifications are not trivial, even putting only the common part and protecting them with ARM, leaving the ARM specific stuff under arch/ like gic etc... will leave a status that is not very nice, so I've decided for now to keep everything on the arm architecture so that who is going to work on unifying the code in common can just take from there and do the proper rework. This serie is not targeting 4.18.
