hello,

     when I declare a buffer statically in a module ( char buf[1024]), and 
 later use __pa(buf) and virt_to_phys(buf),I get an address beyond the physical 
 memory bound. how to get the real physical address of such buffers if I wanna 
 mmap them to user space? 
     thank you very much .

   any instructions pls. fwd to my address.
