m8260_cpm_dpfree( )

Sanjay,

You could try porting the dpfree function in
arch/ppc/8xx_io/commproc.c.  However, this function should only really
be necessary if you wish to rmmod the driver.

Try adding

#ifdef	CONFIG_8260
EXPORT_SYMBOL(m8260_cpm_dpalloc);
#endif

to arch/ppc/kernel/ppc_ksyms.c

Not sure about these problems, but it sounds like you are trying to
build the module standalone, instead of as part of the kernel's "make
modules".  I would recommend the latter as it makes it easier to pick up
the correct gcc flags.
