Merge tag 's390-6.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

 - 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
