Hello Linus,

please pull s390 changes for 5.7. There are some common code changes to
remove s390 specific power management callbacks. Agreed by Rafael:

  s390/mm: cleanup init_new_context() callback (2020-03-28 12:46:12 +0100)

----------------------------------------------------------------
s390 updates for the 5.7 merge window

- Update maintainers. Niklas Schnelle takes over zpci and Vineeth Vijayan
  common io code.

- Extend cpuinfo to include topology information.

- Add new extended counters for IBM z15 and sampling buffer allocation
  rework in perf code.

- Add control over zeroing out memory during system restart.

- CCA protected key block version 2 support and other fixes/improvements
  in crypto code.

- Convert to new fallthrough; annotations.

- Replace zero-length arrays with flexible-arrays.

- QDIO debugfs and other small improvements.

- Drop 2-level paging support optimization for compat tasks. Varios
  mm cleanups.

- Remove broken and unused hibernate / power management support.

- Remove fake numa support which does not bring any benefits.

- Exclude offline CPUs from CPU topology masks to be more consistent
  with other architectures.

- Prevent last branching instruction address leaking to userspace.

- Other small various fixes and improvements all over the code.
