KVM: s390: optimize float int lock: spin_lock_bh --> spin_lock
The floating interrupt lock is only taken in process context. We can replace all spin_lock_bh with standard spin_lock calls. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Christian Ehrhardt <ehrhardt@de.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
