Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20160517' into staging

First batch of s390x patches for 2.7:
- The new machine for 2.7
- Make use of the runtime instrumentation support introduced in
  the kernel
- Enhance our ipl (boot) process: We can now start from devices
  in subchannel sets > 0 as well. As a bonus, the conversion to
  diag308 in the bios allows us to get rid of the gr7 hack.
- Xiaoqiang Zhao's SCLP qomification patches
- Several fixes in the s390x pci implementation
