The initial patch set implementing MIPS KVM does not handle 64-bit
guests or use of the FPU.  This patch set corrects these ABI issues,
and does some very minor clean up.

Changes from v5: Adjust for kvm.h moving to uapi/asm.  Code formatting
                 to achieve line lengths <= 80.

Changes from v4: No code change, just keep more of the code in
                 kvm_mips.c rather than kvm_trap_emul.c

Changes from v3: Use KVM_SET_ONE_REG instead of KVM_SET_MSRS.  Added
                 ENOIOCTLCMD patch.

Changes from v2: Split into five parts, no code change.

David Daney (6):
  mips/kvm: Fix ABI for use of FPU.
  mips/kvm: Fix ABI for use of 64-bit registers.
  mips/kvm: Fix name of gpr field in struct kvm_regs.
  mips/kvm: Use ARRAY_SIZE() instead of hardcoded constants in
  mips/kvm: Fix ABI by moving manipulation of CP0 registers to
  mips/kvm: Use ENOIOCTLCMD to indicate unimplemented ioctls.
