Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20140520' into staging

some s390 patches:

- Enable irqfds on s390 via the new adapter interrupt routing type.
  As a prereq, fix the kvm enable_cap helpers for some compilers and
  split the s390 flic into kvm and non-kvm parts.
- Enable software and hardware debugging support on s390. This needs a
  kernel headers update.
