[Qemu-devel] [QEMU-PPC] [PATCH 12/13] target/ppc: Introduce POWER9 DD2.2 cpu type

[Suraj Jitindar Singh <sjitindarsingh@gmail.com>]

Introduce a POWER9 DD2.2 cpu type with pvr 0x004E1202.

A DD2.2 POWER9 cpu type is needed to enable kvm for pseries tcg guests
since it means they will use the H_ENTER_NESTED hcall to run a guest
rather than trying the generic entry path which will fail.
