   * There are a number of reasons for patching instructions.  Rather than duplicating code
   * all over the place, we put the common stuff here.  Reasons for patching: in-kernel
   * module-loader, virtual-to-physical patch-list, McKinley Errata 9 workaround, and gate
   * shared library.  Undoubtedly, some of these reasons will disappear and others will
   * be added over time.
