Merge tag 's390-5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Vasily Gorbik:

 - 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.
