I think this code needs to be refactored so that it can share with the ehca InfiniBand driver (which should be merged upstream soon). For example, you have ehea_hcall_7arg_7ret() and the ehca driver has an identical ehca_hcall_7arg_7ret().

this stuff should go in <asm-powerpc/hvcall.h> with the other constants, right?

I think this code needs to be refactored so that it can share with the ehca InfiniBand driver (which should be merged upstream soon). For example, you have
ehea_hcall_7arg_7ret()and the ehca driver has an identicalehca_hcall_7arg_7ret().
In genreral this is a good approach, but we think it will be a lengthy process until the same code base is accepted from both - Network community (keep it as simple as possible) vs. IB community (support full IB functionallity). Another thing which makes it quite challenging is that hypervisor calls have subtle little differences between eHCA and eHEA.

Yes, that would be the next step.
