Subject: linux-next: manual merge of the kvms390 tree with the kvm tree

Hi all,

Today's linux-next merge of the kvms390 tree got a conflict in:

  include/linux/kvm_host.h
  arch/s390/kvm/interrupt.c
  arch/s390/kvm/sigp.c

between commits:

  db27a7a37aa0 ("KVM: Provide function for VCPU lookup by id")
  b85de33a1a34 ("KVM: s390: avoid memory overwrites on emergency signal injection")
  152e9f65d66f ("KVM: s390: fix wrong lookup of VCPUs by array index")

from the kvm tree and commit:

  a8ab7a5fd13b ("KVM: Provide function for VCPU lookup by id")
  e896d1d08efc ("KVM: s390: avoid memory overwrites on emergency signal injection")
  32d7bd98e799 ("KVM: s390: fix wrong lookup of VCPUs by array index")

from the kvms390 tree.

These patches used different names for the added function.  I used the
name from the kvm tree (kvm_get_vcpu_by_id).

This also required the following merge patch:

This should probably all be cleaned up in the kvms390 tree.
