+; BDM70: Intel(R) Processor Trace PSB+ Packets May Contain Unexpected Packets.
+;
+; Some Intel Processor Trace packets should be issued only between
+; TIP.PGE and TIP.PGD packets. Due to this erratum, when a TIP.PGE
+; packet is generated it may be preceded by a PSB+ that incorrectly
+; includes FUP and MODE.Exec packets.
