But yep I've merged it anyway. I would just fix this up on top of that, but I don't have a good way to test it, so Balbir I will bounce this back to you to rebase on top of my patch. cheers

The PVR list has been updated and IBM_ARCH_VEC_NRCORES_OFFSET. This provides the cpu versions supported to the hypervisor and in this case tells the hypervisor that the guest supports ISA 3.0 and Power9.
