+	  per device dynamic DMA page table management provided by the Cell
+	  processor's IO Controller.  This support incurs some runtime
+	  overhead and also slightly increases kernel memory usage.  The
+	  current implementation should be considered experimental.
+
+	  This support is mainly for Linux kernel development.  If unsure,
+	  say N.
