- ------------------------------------------------------------------
powerpc updates for 6.8

- Add initial support to recognise the HeXin C2000 processor.

- Add papr-vpd and papr-sysparm character device drivers for VPD & sysparm
retrieval, so userspace tools can be adapted to avoid doing raw firmware
calls from userspace.

- Sched domains optimisations for shared processor partitions on P9/P10.

- A series of optimisations for KVM running as a nested HV under PowerVM.

- Other small features and fixes.
