This patchset adds probing of various architectural features which will be useful for supporting KVM with VZ (MIPS hardware assisted virtualisation extensions). Changes in v2: - Patch 2 changed to handle MIPS32r3+, which can also have a WG bit to allow bits 31:30 to be written. The feature provided is now just the presence of the WG bit rather than the extension of CP0_EBase to 64-bits (which is implied if WG is present on MIPS64). It is based on the mips-for-linux-next~ of the day (commit 0fc44314a7d).
