To have  the compatability i have used  the macro CONFIG_X86_64 in 
.config  .
    

Why do you need to differentiate code executed on 32 bits platforms
from code executed on 64 bits platform ? Generally speaking, your code
should be portable, and not rely on CONFIG_X86_64 or other options of
the same kind.

  

I want to assign some data to a long pointer variable SysAdddr.

#ifdef CONFIG_64
*(SysAddr + num_items) = (0xaa55aa55aa000000 + num_items);
#else
*(SysAddr + num_items) = (0x11220000 + (num_items));
#endif
If it is 64 but system i should assign 64 bit or else 32 bit data.
Can i have any other option/method ?

Thanks
