Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20151111' into staging

Hopefully last big batch of s390x patches, including:
- bugfixes for LE host and for pci translation
- MAINTAINERS update
- hugetlbfs enablement (kernel patches pending)
- boot from El Torito iso images on virtio-blk
  (boot from scsi pending)
- cleanup in the ipl device code

There's also a helper function for resetting busless devices in the
qdev core in there.
