Merge tag 's390-5.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Vasily Gorbik:

 - a few ptrace fixes mostly for strace and seccomp_bpf kernel tests
   findings

 - cleanup unused pm callbacks in virtio ccw

 - replace kmalloc + memset with kzalloc in crypto

 - use $(LD) for vDSO linkage to make clang happy

 - fix vDSO clock_getres() to preserve the same behaviour as
   posix_get_hrtimer_res()

 - fix workqueue cpumask warning when NUMA=n and nr_node_ids=2

 - reduce SLSB writes during input processing, improve warnings and
   cleanup qdio_data usage in qdio

 - a few fixes to use scnprintf() instead of snprintf()
