 * s/w module to access the RELA sections in the ELF image. These are used to
 * apply the relocations applied by the module loader in reverse, so that we
 * can reconstruct the image that was used to derive the HMAC used by the
 * integrity check.
 *
 * The first .long of each entry will be populated by the module loader based
 * on the actual placement of the respective RELA section in memory. The second
 * .long carries the RELA entry count, and is populated by the host tool that
 * also generates the HMAC of the contents of .text and .rodata.
