[Qemu-devel] [PATCH v5 0/8] Support arm-gic-kvm save/restore

[Christoffer Dall]

Implement support to save/restore the ARM KVM VGIC state from the
kernel.  The basic appraoch is to transfer state from the in-kernel VGIC
to the emulated arm-gic state representation and let the standard QEMU
vmstate save/restore handle saving the arm-gic state.  Restore works by
reversing the process.

The first patches adds missing features and fixes issues with the
arm-gic implementation in qemu in preparation for the actual
save/restore logic.

The patches depend on the device control patch series sent out earlier,
which can also be found here:
git://git.linaro.org/people/cdall/qemu-arm.git migration/device-ctrl-v4

The whole patch series based on top of the above can be found here:

Changes are described in the individual patches.
