[Qemu-devel] [PATCH for-2.5 0/8] s390x: storage key migration

[Cornelia Huck <cornelia.huck@de.ibm.com>]

Here's the first batch of s390x patches I plan to send for 2.5.

This one deals with storage keys, which may be set by guests and
lacked a proper resting place so far. Introducing a device (that
is backed by the KVM_S390_{SET,GET}_SKEYS ioctls in the kvm case)
allows us to migrate them properly.

Also available as a branch on

git://github.com/cohuck/qemu s390-skey
