* QEMU: implement full cp15 sync with kernel [http://cards.linaro.org/browse/VIRT-49] by Peter Maydell

Done: - last bits of patch cleanup complete - realized that KVM migration can be tested without any timer or vgic patches; did so and sent first version of patches out to qemu-devel

* QEMU: fix cp15 register reset [http://cards.linaro.org/browse/VIRT-50] by Peter Maydell

Done: - VIRT-49 patches on their own break reset handling for the KVM case, so we need to include VIRT-50 work in the same patchset. Fortunately it turned out to be a small extension; patch done and tested, and submitted as part of the VIRT-49 patchset.

* QEMU: test migration [http://cards.linaro.org/browse/VIRT-55] by Peter Maydell

Working on: - started to draft basic notes on what we want to test: https://wiki.linaro.org/PeterMaydell/MigrationTesting

Done: - got feedback from Marc Zyngier and Peter Maydell. - produced new version, sent for review.

* kernel: agree on a data structure to hold GIC state [http://cards.linaro.org/browse/VIRT-44] by Christoffer Dall

Working on: - Investigating, taking the task from Andre.

* add some basic unit testing bits to LAVA [http://cards.linaro.org/browse/VIRT-79] by Christoffer Dall
