Linus Torvalds 65ad409e63 more s390 updates for 6.11 merge window
- 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
