Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20150430' into staging
First pile of s390x patches for 2.4, including:
- some cleanup patches
- sort most of the s390x devices into categories
- support for the new STSI post handler, used to insert vm name and
friends
- support for the new MEM_OP ioctl (including access register mode)
for accessing guest memory
