9f9d86e1e9 s390/uprobes: fix address space annotation
Remove __user address space annotation for sim_stor_event() calls since it
generates false positive warnings from sparse.

8d1a2427d8 s390/uprobes: fix user space PER events
If uprobes are single stepped for example with gdb, the behavior should
now be correct. Before this patch, when gdb was single stepping a uprobe,
the result was a SIGILL.
When PER is active for any storage alteration and a uprobe is hit, a storage
alteration event is indicated. These over indications are filterd out by gdb,
if no change has happened within the observed area.
