  s390: fix syscall_get_error for compat processes (2020-06-17 23:05:05 +0200)

----------------------------------------------------------------
s390 fixes for 5.8-rc2

- 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.

- Few fixes to use scnprintf() instead of snprintf().
