Merge tag 's390-6.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Vasily Gorbik:
- Fix KMSAN build breakage caused by the conflict between s390 and
mm-stable trees
- Add KMSAN page markers for ptdump
- Add runtime constant support
- Fix __pa/__va for modules under non-GPL licenses by exporting
necessary vm_layout struct with EXPORT_SYMBOL to prevent linkage
problems
- Fix an endless loop in the CF_DIAG event stop in the CPU Measurement
Counter Facility code when the counter set size is zero
- Remove the PROTECTED_VIRTUALIZATION_GUEST config option and enable
its functionality by default
- Support allocation of multiple MSI interrupts per device and improve
logging of architecture-specific limitations
- Add support for lowcore relocation as a debugging feature to catch
all null ptr dereferences in the kernel address space, improving
detection beyond the current implementation's limited write access
protection
- Clean up and rework CPU alternatives to allow for callbacks and early
patching for the lowcore relocation
