For gicv3 its, I believe, the below series for qemu and kernel is required for 
gicv3-its

[RFC PATCH v3 0/5] vITS support
https://lists.gnu.org/archive/html/qemu-devel/2015-11/msg05197.html

and in kernel CONFIG_HAVE_KVM_MSI must be enabled so that qemu sees MSI 
capability KVM_CAP_SIGNAL_MSI

This has a dependency on gsi routing support
KVM: arm/arm64: gsi routing support
https://lkml.org/lkml/2015/6/29/290

I had both the above series in 4.2 in my local 4.2 tree.
