       The  pmap_map() function maps a range of physical addresses into kernel virtual address (KVA) space, from
       start to end, with protection bits prot.

       The value passed in *virt is treated as a hint for the virtual address of the beginning of the mapping.

       The prot argument is currently ignored by machine-dependent implementations.

       Architectures which can support a direct mapped physical to virtual region  can  return  the  appropriate
       address within that region, leaving *virt unchanged.

       pmap_map — map a physical memory range into kernel virtual address (KVA) space

       The  pmap_map()  function returns the virtual address of the beginning of the mapping, if the mapping was
       successfully made; *virt will also be updated with the first usable address after the mapped region.

       If the function is unsuccessful, NULL is returned.
