Merge tag 's390-5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
- Support for kernel address space layout randomization
- Add support for kernel image signature verification
- Convert s390 to the generic get_user_pages_fast code
- Convert s390 to the stack unwind API analog to x86
- Add support for CPU directed interrupts for PCI devices
- Provide support for MIO instructions to the PCI base layer, this will
allow the use of direct PCI mappings in user space code
- Add the basic KVM guest ultravisor interface for protected VMs
- Add AT_HWCAP bits for several new hardware capabilities
- Update the CPU measurement facility counter definitions to SVN 6
- Arnds cleanup patches for his quest to get LLVM compiles working
- A vfio-ccw update with bug fixes and support for halt and clear
- Improvements for the hardware TRNG code
- Another round of cleanup for the QDIO layer
- Numerous cleanups and bug fixes
