          Instead of emitting them as absolute values in the native word size,
          emit the symbol references in the kallsyms table as 32-bit entries,
-         each containing either an absolute value in the range [0, S32_MAX] or
-         a relative value in the range [base, base + S32_MAX], where base is
-         the lowest relative symbol address encountered in the image.

          On 64-bit builds, this reduces the size of the address table by 50%,
          but more importantly, it results in entries whose values are build
