This series is based on my recent VZ series. My hope is to take this series via the MIPS KVM tree for 4.12. This series implements support for Cavium Octeon III CPUs in KVM (primarily for VZ hardware, but trap & emulate should also work). Patch 1 adds register accesses and definitions for the virtualization related Cavium specific COP0 registers, which will be used by later patches. Patches 2-7 make various changes to allow KVM to work on Cavium Octeon III, with Patch 5 doing the all important Cavium specific partitioning of the TLB between root and guest and guest IRQ setup. Finally patch 8 selects HAVE_KVM from CPU_CAVIUM_OCTEON to allow KVM to be enabled.
