Merge tag 'kvm-s390-20140730' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into kvm-next

Two fixes for recently introduced regressions
- a memory leak on busy SIGP
- pontentially lost SIGP stop in rare situations (shutdown loops)

The first issue is not part of a released kernel. The 2nd issue is
present in all KVM versions, but did not trigger before commit
7dfc63cf977447e09b1072911c2 (KVM: s390: allow only one SIGP STOP
(AND STORE STATUS) at a time) with Linux as a guest.
So no need for cc stable
