    We need to cope with things like:
    
    $ objdump  -d --no-show-raw -S -C /lib/modules/3.4.0-rc2+/build/vmlinux
    <SNIP>
    ffffffff8125ec60 <copy_user_generic_unrolled>:
     * Output:
     * eax uncopied bytes or 0 if successful.
     */
    ENTRY(copy_user_generic_unrolled)
    	CFI_STARTPROC
    	cmpl $8,%edx
    ffffffff8125ec60:	cmp    $0x8,%edx
    	jb 20f		/* less then 8 bytes, go to byte copy loop */
    ffffffff8125ec63:	jb     ffffffff8125ecf5 <copy_user_generic_unrolled+0x95>
    	ALIGN_DESTINATION
    <SNIP>

    Probably expect that the length of the addr field be the same...
    
    Lazy move for now, back to supporting suppressing the address on callq lines...
