Are you happy to do the same?
We intend to merge the s390 variant also for v4.10. Our approach has changed however: we came to the conclusion that having a per-cpu preempt count will generate better code on s390; so Martin implemented that. And while being at it he also moved the rest of the s390 specific stuff out of our struct thread_info. The corresponding patches will be pushed to git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git features branch soon. In result we will have a struct thread_info that only contains the flags field like x86 does. So we don't depend an any other patches anymore...
