-/**
- * @file
- *
- * Access to external ("user") memory
- *
- * gPXE often needs to transfer data between internal and external
- * buffers.  On i386, the external buffers may require access via a
- * different segment, and the buffer address cannot be encoded into a
- * simple void * pointer.  The @c userptr_t type encapsulates the
- * information needed to identify an external buffer, and the
- * copy_to_user() and copy_from_user() functions provide methods for
- * transferring data between internal and external buffers.
- *
- * Note that userptr_t is an opaque type; in particular, performing
- * arithmetic upon a userptr_t is not allowed.
