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.
