[Qemu-devel] [PULL 00/20] s390x/kvm: Features and fixes for 2.3

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

Peter,

this pull reuqest contains a header sync to 4.0-rc3. This should cause
no merge conflicts with other header syncs against 4.0-rc2. So here
is the s390 pull request.

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 (2015-03-10 09:26:33 +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: rebuild BIOS

David Hildenbrand (10):
      s390x: introduce defines for SIGP condition codes
      s390x/kvm: more details for SIGP handler with one destination vcpu
