[Qemu-devel] [PULLv2] s390x/kvm: Features and fixes for 2.3

[Christian Borntraeger <borntraeger@de.ibm.com>]

Peter,

here is the 2nd version (only one patch changed) that hopefully
compiles fine on 32 bit hosts.
I only added that patch as followup mail.


The following changes since commit 277263e1b320d759a760ba6c5ea75ec268f929e5:

  Merge remote-tracking branch 'remotes/agraf/tags/signed-ppc-for-upstream' into staging (2015-03-09 14:04:14 +0000)

  s390-ccw: rebuild BIOS (2015-03-11 11:15:45 +0100)

----------------------------------------------------------------
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

----------------------------------------------------------------
Christian Borntraeger (4):
      synchronize Linux headers to 4.0-rc3
      s390-ccw.img: Allow bigger ramdisk sizes or offsets
      s390-ccw.img: Reinitialize guessing on reboot
      s390-ccw: rebuild BIOS

David Hildenbrand (10):
      s390x: introduce defines for SIGP condition codes
      s390x/kvm: more details for SIGP handler with one destination vcpu
      s390x/kvm: pass the SIGP instruction parameter to the SIGP handler
      s390x/kvm: helper to set the SIGP status in SigpInfo
      s390x/kvm: trace all SIGP orders
      s390x/kvm: implement handling of new SIGP orders
      s390x/kvm: SIGP START is only applicable when STOPPED
      s390x: add function to deliver restart irqs
      s390x/kvm: deliver SIGP RESTART directly if stopped
      s390x/kvm: enable the new SIGP handling in user space

Dominik Dingel (1):
      s390x/kvm: passing max memory size to accelerator

Markus Armbruster (3):
      virtio-s390: s390_virtio_device_init() can't fail, simplify
      virtio-s390: Convert to realize()
      virtio-ccw: Convert to realize()

Thomas Huth (2):
      elf-loader: Provide the possibility to relocate s390 ELF files
      s390/bios: Make the s390-ccw.img relocatable
