[PATCH v2 0/5] MIPS: Add feature probing ready for KVM/VZ

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).

James Hogan (5):
  MIPS: Define & use CP0_EBase bit definitions
  MIPS: Add defs & probing of extended CP0_EBase
  MIPS: Add defs & probing of BadInstr[P] registers
  MIPS: Add defs & probing of [X]ContextConfig
  MIPS: Add perf counter feature
