><P
> The returned physical address is the physical (CPU) mapping for
the memory address given. It is only valid to use this function on
addresses directly mapped or allocated via kmalloc.
</P
><P
> This function does not give bus mappings for DMA transfers. In
almost all conceivable cases a device driver should not be using
this function
