The list of GICv2 patches candidate for backporting are: #10, #11, #12, #13.

For GICv3, see my comment below.

I guess you mean GICv3 for the last one?

I agree that there is no hardware available, but someone may want to use
the latest Xen release (currently 4.5) on their GICv3 internal board.

IHMO, GICv3 was not a tech-preview on Xen 4.5. At least we never clearly
say it was. If it's the case we should write-down on the features list.
