Linus Torvalds 2bb919b62f s390 updates for the 5.14 merge window
- Rework inline asm to get rid of error prone "register asm" constructs,
   which are problematic especially when code instrumentation is enabled. In
   particular introduce and use register pair union to allocate even/odd
   register pairs. Unfortunately this breaks compatibility with older
   clang compilers and minimum clang version for s390 has been raised to 13.

 - Fix gcc 11 warnings, which triggered various minor reworks all over
   the code.
 
 - Add zstd kernel image compression support.
 
 - Rework boot CPU lowcore handling.
 
 - De-duplicate and move kernel memory layout setup logic earlier.
 
 - Few fixes in preparation for FORTIFY_SOURCE performing compile-time
   and run-time field bounds checking for mem functions.
 
 - Remove broken and unused power management support leftovers in s390
   drivers.
 
 - Disable stack-protector for decompressor and purgatory to fix buildroot
   build.
 
 - Fix vt220 sclp console name to match the char device name.
 
 - Enable HAVE_IOREMAP_PROT and add zpci_set_irq()/zpci_clear_irq() in
   zPCI code.
 
 - Remove some implausible WARN_ON_ONCEs and remove arch specific counter
   transaction call backs in favour of default transaction handling in
   perf code.
 
 - Extend/add new uevents for online/config/mode state changes of
   AP card / queue device in zcrypt.
 
 - Minor entry and ccwgroup code improvements.
 
 - Other small various fixes and improvements all over the code.
