Linus Torvalds d8cb068359 s390 updates for 6.16 merge window
- Large rework of the protected key crypto code to allow for asynchronous
   handling without memory allocation
 
 - Speed up system call entry/exit path by re-implementing lazy ASCE
   handling
 
 - Add module autoload support for the diag288_wdt watchdog device driver
 
 - Get rid of s390 specific strcpy() and strncpy() implementations, and
   switch all remaining users to strscpy() when possible
 
 - Various other small fixes and improvements
