Consequently, remove it from the documentation.

-no_force_psb    This is a driver option and is not in the IA32_RTIT_CTL MSR.

-                It stops the driver resetting the byte count to zero whenever
-                enabling the trace (for example on context switches) which in
-                turn results in no PSB being forced.  However some processors
-                will produce a PSB anyway.
-
-                In any case, there is still a PSB when the trace is enabled for
-                the first time.
-
-                no_force_psb can be used to slightly decrease the trace size but
-                may make it harder for the decoder to recover from errors.
-
-                no_force_psb is not selected by default.
