  s390/vmemmap: coding style updates (2020-07-27 10:34:19 +0200)

----------------------------------------------------------------
- Add support for function error injection.

- Add support for custom exception handlers, as required by BPF_PROBE_MEM.

- Add support for BPF_PROBE_MEM.

- Add trace events for idle enter / exit for the s390 specific idle
  implementation.

- Remove unused zcore memmmap device.

- Remove unused "raw view" from s390 debug feature.

- AP bus + zcrypt device driver code refactoring.

- Provide cex4 cca sysfs attributes for cex3 for zcrypt device driver.

- Expose only minimal interface to walk physmem for mm/memblock. This
  is a common code change and it has been agreed on with Mike Rapoport
  and Andrew Morton that this can go upstream via the s390 tree.

- Rework of the s390 vmem/vmmemap code to allow for future memory hot
  remove.

- Get rid of FORCE_MAX_ZONEORDER to finally allow for order-10
  allocations again, instead of only order-8 allocations.

- Various small improvements and fixes.
