    *  Naming schemes for constants in these files:
    *
    *  M_xxx            MASK constant (identifies bits in a register).
    *                   For multi-bit fields, all bits in the field will
    *                   be set.
    *
    *  K_xxx            "Code" constant (value for data in a multi-bit
    *                   field).  The value is right justified.
    *
    *  V_xxx            "Value" constant.  This is the same as the
    *                   corresponding "K_xxx" constant, except it is
    *                   shifted to the correct position in the register.
    *
    *  S_xxx            SHIFT constant.  This is the number of bits that
    *                   a field value (code) needs to be shifted
    *                   (towards the left) to put the value in the right
    *                   position for the register.
    *
    *  A_xxx            ADDRESS constant.  This will be a physical
    *                   address.  Use the MIPS_PHYS_TO_KSEG1 macro to
    *                   generate a K1SEG address.
    *
    *  R_xxx            RELATIVE offset constant.  This is an offset from
    *                   an A_xxx constant (usually the first register in
    *                   a group).
    *
    *  G_xxx(X)         GET value.  This macro obtains a multi-bit field
    *                   from a register, masks it, and shifts it to
    *                   the bottom of the register (retrieving a K_xxx
    *                   value, for example).
    *
    *  V_xxx(X)         VALUE.  This macro computes the value of a
    *                   K_xxx constant shifted to the correct position
    *                   in the register.
