 /**
- * Lazily sync in the FPU/XMM state
+ * Lazily sync the guest-FPU/XMM state if possible.
+ *
+ * Loads the guest-FPU state, if it isn't already loaded, into the CPU if the
+ * guest is not expecting a #NM trap.
  *
  * @returns VBox status code.
- * @param   pVM         Pointer to the VM.
- * @param   pVCpu       Pointer to the VMCPU.
- * @param   pCtx        Pointer to the guest CPU context.
+ * @retval VINF_SUCCESS           if the guest FPU state is loaded.
+ * @retval VINF_EM_RAW_GUEST_TRAP if it is a guest trap.
+ *
+ * @remarks This relies on CPUMIsGuestFPUStateActive() reflecting reality.
