Pull more s390 updates from Vasily Gorbik:
- Get rid of s390 specific use of two PTEs per 4KB page with complex
half-used pages tracking. Using full 4KB pages for 2KB PTEs increases
the memory footprint of page tables but drastically simplify mm code,
removing a common blocker for common code changes and adaptations
- Simplify and rework "cmma no-dat" handling. This is a follow up for
recent fixes which prevent potential incorrect guest TLB flushes
- Add perf user stack unwinding as well as USER_STACKTRACE support for
user space built with -mbackchain compile option
- Add few missing conversion from tlb_remove_table to tlb_remove_ptdesc
- Fix crypto cards vanishing in a secure execution environment due to
asynchronous errors
- Avoid reporting crypto cards or queues in check-stop state as online
- Fix null-ptr deference in AP bus code triggered by early config
change via SCLP
- Couple of stability improvements in AP queue interrupt handling
