It's illegal because it can sleep. Use a two step lookup scheme instead. First look up the vm_struct, then change the direct mapping, then finally unmap it. That's ok because nobody can change the particular virtual address range as long as the vm_struct is still in the global list. Also added some LinuxDoc documentation to iounmap.
