[PATCH] i386/x86-64: Don't call change_page_attr with a spinlock held
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.
