FWIW, the patch below is also needed to fix a compile error.
I'll take care it gets upstream independently of your work.

Subject: [PATCH 2/2] s390/mm: provide emtpy check_pgt_cache() function
All architectures need to provide a check_pgt_cache() function. The s390 one
got lost somewhere.
So reintroduce it to prevent future compile errors e.g. if Thomas Gleixner's
idle loop rework patches get merged.
