c - "__floatsidf" undefined warning when compiling kernel module -

I was writing a loadable kernel module and when it is attempted to compile, the following message in the linker failed Lives:

  *** Warning: "__floatsidf" [/ testing / Something.ko] undefined!   
 I am not using floating point variables, so it is not so. What is the reason for such errors?  
 Note: I  Linux Ubuntu kernel v. Using 3.5.0-23-generic    
 
  __flotidid  is a runtime routine. There is a line in your project that looks like:  
  double foo = bar;   
 Or something similar, where  bar  is a 32-bit integer, it may also be that you have  libm  functions (or somebody other functions, which are actually a call to one of the), which  double  with an integer parameter:  
  Foo = pow (time , Falcon);   
 Where  the bar  or  baz  (or both) is an integer.  
 Without showing some code,  
 To narrow it, check the object files before generating your compiler (before you link them) and reference to that symbol See in disassembly for - who should tell what is happening to you this ceremony.  
 Here is an example of what I mean first - source code:  
  #include  Int function (int x, int y) {return pa (x, y); }   
 Pretty straightforward, right? Now, I am going to compile it for ARM and separation have:
