Very Computer

I am currently writing a Linux driver to drive IO using the MPC8240
PortX interface. Our output device can only be accessed using 64 bit
transfer. I use s64 variable type and when the code is compiled it uses
floating point instruction as it is the only way for a MPC8240 to do 64
bit wide access. The code executes correctly but each time a floating
point operation occurs the following message appears on the console :
    "floating point used in kernel "

How can I remove this message ?

Thanks
