Merge tag 's390-6.14-6' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Vasily Gorbik:

 - Fix return address recovery of traced function in ftrace to ensure
   reliable stack unwinding

 - Fix compiler warnings and runtime crashes of vDSO selftests on s390
   by introducing a dedicated GNU hash bucket pointer with correct
   32-bit entry size

 - Fix test_monitor_call() inline asm, which misses CC clobber, by
   switching to an instruction that doesn't modify CC
