+ * sgx_calc_section_metric() - Calculate an EPC section metric
+ * @low:	low 32-bit word from CPUID:0x12:{2, ...}
+ * @high:	high 32-bit word from CPUID:0x12:{2, ...}
+ *
  * A section metric is concatenated in a way that @low bits 12-31 define the
  * bits 12-31 of the metric and @high bits 0-19 define the bits 32-51 of the
  * metric.
