Hi Linus,
please pull s390 updates for the 5.19 merge window. Note that this
contains one small patch which touches generic entry code, and the
corresponding pieces within x86. This has been Acked by Thomas Gleixner
and Peter Zijlstra.
Thanks,
Heiko

s390/head: get rid of 31 bit leftovers (2022-05-18 13:31:07 +0200)
----------------------------------------------------------------
s390 updates for 5.19 merge window
- Make use of the IBM z16 processor activity instrumentation facility
to count cryptography operations: add a new PMU device driver so
that perf can make use of this.
- Add new IBM z16 extended counter set to cpumf support.
- Add vdso randomization support.
- Add missing KCSAN instrumentation to barriers and spinlocks, which
should make s390's KCSAN support complete.
- Add support for IPL-complete-control facility: notify the hypervisor
that kexec finished work and the kernel starts.
- Improve error logging for PCI.
- Various small changes to workaround llvm's integrated assembler
limitations, and one bug, to make it finally possible to compile the
kernel with llvm's integrated assembler. This also requires to raise
the minimum clang version to 14.0.0.
- Various other small enhancements, bug fixes, and cleanups all over
the place.
