In linux kernel since version 5.2 (release Date: 2019-07-07)
Enable workaround for ARM Neoverse-N2 erratum 2067961
Affected cores may fail to flush the trace data on a TSB instruction, when
the PE is in trace prohibited state. This will cause losing a few bytes
of the trace cached.
Workaround is to issue two TSB consecutively on affected cores.
If unsure, say Y.
