[PATCH V4 0/2] powerpc: add support for ISA v2.07 compat level

Version v3.00 of the ISA added a new compat level to the processor
compatibility register (PCR), an ISA v2.07 compatibility mode.

Upstream QEMU already supports this so it may as well go into the kernel
now.

Change Log:

V1 -> V2: 
- Reworked logic to set and mask the PCR, no functional change

V2 -> V3:
- Reworked logic again, no functional change

V3 -> V4:
- Added a comment in the first patch to clarify why a 'dummy' PCR v3.00
  value is needed

Suraj Jitindar Singh (2):
  powerpc: Define new ISA v3.00 logical PVR value and PCR register value
  powerpc/kvm: Update kvmppc_set_arch_compat() for ISA v3.00
