s390/cio: replace deprecated strncpy with strscpy (2023-10-25 15:08:30 +0200)
----------------------------------------------------------------
s390 updates for the 6.7 merge window
- Get rid of private VM_FAULT flags
- Add word-at-a-time implementation
- Add DCACHE_WORD_ACCESS support
- Cleanup control register handling
- Disallow CPU hotplug of CPU 0 to simplify its handling complexity,
following a similar restriction in x86
- Optimize pai crypto map allocation
- Update the list of crypto express EP11 coprocessor operation modes
- Fixes and improvements for secure guests AP pass-through
- Several fixes to address incorrect page marking for address translation
with the "cmma no-dat" feature, preventing potential incorrect guest
TLB flushes
- Fix early IPI handling
- Several virtual vs physical address confusion fixes
- Various small fixes and improvements all over the code
