Merge tag 's390-5.9-6' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Vasily Gorbik:

 - Fix order in trace_hardirqs_off_caller() to make locking state
   consistent even if the IRQ tracer calls into lockdep again. Touches
   common code. Acked-by Peter Zijlstra.

 - Correctly handle secure storage violation exception to avoid kernel
   panic triggered by user space misbehaviour.

 - Switch the idle->seqcount over to using raw_write_*() to avoid
  "suspicious RCU usage".

 - Fix memory leaks on hard unplug in pci code.

 - Use kvmalloc instead of kmalloc for larger allocations in zcrypt.

 - Add few missing __init annotations to static functions to avoid
   section mismatch complains when functions are not inlined.
