- *
- * The scif_register() function opens a window, a range of whole pages of the
- * registered address space of the endpoint epd, starting at offset po and
- * continuing for len bytes. The value of po, further described below, is a
- * function of the parameters offset and len, and the value of map_flags. Each
- * page of the window represents the physical memory page which backs the
- * corresponding page of the range of virtual address pages starting at addr
- * and continuing for len bytes. addr and len are constrained to be multiples
- * of the page size. A successful scif_register() call returns po.
- *
- * When SCIF_MAP_FIXED is set in the map_flags argument, po will be offset
- * exactly, and offset is constrained to be a multiple of the page size. The
- * mapping established by scif_register() will not replace any existing
- * registration; an error is returned if any page within the range [offset,
- * offset + len - 1] intersects an existing window.
- *
- * When SCIF_MAP_FIXED is not set, the implementation uses offset in an
- * implementation-defined manner to arrive at po. The po value so chosen will
- * be an area of the registered address space that the implementation deems
- * suitable for a mapping of len bytes. An offset value of 0 is interpreted as
- * granting the implementation complete freedom in selecting po, subject to
- * constraints described below. A non-zero value of offset is taken to be a
- * suggestion of an offset near which the mapping should be placed. When the
- * implementation selects a value for po, it does not replace any extant
- * window. In all cases, po will be a multiple of the page size.
- *
- * The physical pages which are so represented by a window are available for
- * access in calls to mmap(), scif_readfrom(), scif_writeto(),
- * scif_vreadfrom(), and scif_vwriteto(). While a window is registered, the
- * physical pages represented by the window will not be reused by the memory
- * subsystem for any other purpose. Note that the same physical page may be
- * represented by multiple windows.

- *
- * The scif_register_pinned_pages() function opens a window, a range of whole

- * the window represents a corresponding physical memory page of the range
- * represented by pinned_pages; the length of the window is the same as the
- * length of range represented by pinned_pages. A successful
- * scif_register_pinned_pages() call returns po as the return value.

- *
- * When SCIF_MAP_FIXED is not set, the implementation uses offset in an
- * implementation-defined manner to arrive at po. The po so chosen will be an
- * area of the registered address space that the implementation deems suitable
- * for a mapping of the required size. An offset value of 0 is interpreted as
- * granting the implementation complete freedom in selecting po, subject to
- * constraints described below. A non-zero value of offset is taken to be a
- * suggestion of an offset near which the mapping should be placed. When the
- * implementation selects a value for po, it does not replace any extant
- * window. In all cases, po will be a multiple of the page size.
- *
- * The physical pages which are so represented by a window are available for
- * access in calls to scif_get_pages(), scif_readfrom(), scif_writeto(),
- * scif_vreadfrom(), and scif_vwriteto(). While a window is registered, the
