[PATCH] PPC/CAS Add support for power9 in ibm_architecture_vec
From: Balbir Singh <bsingharora@gmail.com>
Date: 2016-11-29 12:12:01
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.
