+ * Notes on guest address spaces.
+ *
+ * Address spaces are loosely coupled to virtual machines. The default is for
+ * a guest with an index of 1 to use address space 1, 2 to use 2, etc. However,
+ * any guest may be launched using any address space and any address space may be the
+ * target for a map or unmap function. Note that the (un)map list functions may pass in
+ * an address space ID on a page-by-page basis.
+ *
+ * An address space is instantiated either explicitly by mapping something into it, or
+ * implicitly by launching a guest with it.
+ *
+ * An address space is destroyed explicitly by kVmmTearDownAll or kVmmUnmapAllPages. It is
+ * destroyed implicitly by kVmmTearDownContext. The latter is done in order to remain
+ * backwards compatible with the previous implementation, which does not have decoupled
+ * guests and address spaces.
+ *
+ * An address space supports the maximum virtual address supported by the processor.
+ * The 64-bit variant of the mapping functions can be used on non-64-bit machines. If an
+ * unmappable address (e.g., an address larger than 4GB-1 on a 32-bit machine) is requested,
+ * the operation fails with a kVmmInvalidAddress return code.
+ *
+ * Note that for 64-bit calls, both host and guest are specified at 64-bit values.
