Merge remote-tracking branch 'remotes/borntraeger/tags/s390x-20150310' into staging
s390x/kvm: Features and fixes for 2.3
- an extension to the elf loader to allow relocations
- make the ccw bios relocatable. This allows for bigger ramdisks
or smaller guests
- Handle all slow SIGPs in QEMU (instead of kernel) for better
compliance and correctness
- tell the KVM module the maximum guest size. This allows KVM
to reduce the number or page table levels
- Several fixes/cleanups

* remotes/borntraeger/tags/s390x-20150310:
s390-ccw: rebuild BIOS
s390/bios: Make the s390-ccw.img relocatable
elf-loader: Provide the possibility to relocate s390 ELF files
s390-ccw.img: Reinitialize guessing on reboot
s390-ccw.img: Allow bigger ramdisk sizes or offsets
s390x/kvm: passing max memory size to accelerator
virtio-ccw: Convert to realize()
virtio-s390: Convert to realize()
virtio-s390: s390_virtio_device_init() can't fail, simplify
s390x/kvm: enable the new SIGP handling in user space
s390x/kvm: deliver SIGP RESTART directly if stopped
s390x: add function to deliver restart irqs
s390x/kvm: SIGP START is only applicable when STOPPED
s390x/kvm: implement handling of new SIGP orders
s390x/kvm: trace all SIGP orders
s390x/kvm: helper to set the SIGP status in SigpInfo
s390x/kvm: pass the SIGP instruction parameter to the SIGP handler
s390x/kvm: more details for SIGP handler with one destination vcpu
s390x: introduce defines for SIGP condition codes
synchronize Linux headers to 4.0-rc3
