LinuxQuestions.org - Compiling kernel module errors with kernel 2.6.32-279

I am trying to compile and install a kernel module on a Red Hat Enterprise Linux 6.3 box. I run into an issue with a redefinition of the __pa() function. I'm not sure this module has been compiled on this version of the kernel. I've done a bunch of programming, but not on Linux. Can anyone help me figure this out?

Thanks,
Jeff

Here's my make output:
