 *
 * To reserve the appropriate amount of space in "patch_tbl", modify the
 * constant PATCH_ENTRIES below to reflect the number of load/store with
 * update instruction pairs in the application.
 *
 * To determine how many of these situations exist in an application, run the
 * patch utility against the application with PATCH_ENTRIES set to 1.  The
 * initial run of the patch utility will tell you the exact value to set
 * PATCH_ENTRIES for the application.  PATCH_ENTRIES can be set to a larger
 * value than required if desired.
