The patch for this is in qemu-linaro: http://git.linaro.org/gitweb?p=qemu/qemu-linaro.git;a=commitdiff;h=a4b117368cb2b34d079f9f367777b691cca87b4b not very complicated in itself but it sits on top of a large set of QEMU GIC refactoring patches. Most of the refactoring I've already sent to qemu-devel as it's not KVM-specific; I'll post the final two patches here for code review. -- PMM
