The reason it is currently a separate patch is layering: the shared header include/linux/bao.h is introduced by the I/O dispatcher patch (4/6), while the IPC helper that would use the constant is introduced earlier (2/6). To fold this away cleanly I will move creation of include/linux/bao.h into 2/6 (with the IPC hypercall ID) and have 4/6 only add the Remote I/O ID, so the arch helpers are parameter-free from the start and this patch disappears. I will do that in v4 (I kept it separate in v3 only so the changelog against v2 stays readable, and it now has a proper "why" message). If you would prefer I fold it immediately, I am happy to respin.
