DESCRIPTION

16       The returned physical address is the physical (CPU) mapping for the
17       memory address given. It is only valid to use this function on
18       addresses directly mapped or allocated via kmalloc.

20       This function does not give bus mappings for DMA transfers. In almost
21       all conceivable cases a device driver should not be using this function
