to receive the following updates:
One small improvement for the cputime accounting, two bug fixes and
an update for the default configuration files.
Heiko Carstens (2):
s390/vdso: fix stack corruption
s390/ftrace: add ftrace_graph_is_dead() check
Martin Schwidefsky (2):
s390/time: use stck clock fast for do_account_vtime
s390: update default configuration
