This patchset is based on the one titled "[PATCH 0/5] MIPS: Add feature
probing ready for KVM/VZ" which I submitted earlier today.
It adds general MIPS handling and exposure of the VZ COP0 and hardware
guest state.
Specifically:
- Access to VZ specific COP0 registers.
- Access to the COP0 registers of the VZ "guest" context (which are
mostly separate to the normal ("root") COP0 registers).
- Probing and exposure of various VZ features.
- Probing and exposure of various features available in the VZ guest
context.
- Inline helpers for VZ specific COP0 instructions such as those for
accessing the guest TLB.
- Handling & dumping of extra root TLB state. Specifically the GuestID,
which is an optional field added to the root TLB to distinguish the
normal root virtual address space with a GuestID of 0 from multiple
guest physical address spaces with non-zero GuestIDs.

MIPS: Add register definitions for VZ ASE registers
MIPS: Add guest CP0 accessors
MIPS: Add probing & defs for VZ & guest features
MIPS: dump_tlb: Preserve and dump GuestID
