DESCRIPTION
     The store functions are designed to copy small amounts of data to user-

     The store routines provide the following functionality:

     subyte()	 Stores a byte of data to the user-space address base.

     suword()	 Stores a word of data to the user-space address base.

     suword16()	 Stores 16 bits of of data to the user-space address base.

     suword32()	 Stores 32 bits of of data to the user-space address base.

     suword64()	 Stores 64 bits of of data to the user-space address base.

     suswintr()	 Stores a short word of data to the user-space address base.
		 This function is safe to call during an interrupt context.

RETURN VALUES
     The store functions return 0 on success or -1 on failure.
