Jon,

This version should be good to go.  
Applied, thanks.
And I now see I sent an older version that had a typo in it :-p


+			Note, saving the trace buffer across reboots does require that the system
+			is set up to not wipe memory. For instance, CONFIG_RESET_ATTACK_MITIGATION
+			can force a memory reset on boot which will clear any trace that was stored.
+			This is just one of many ways that can clear memory. Make sure you system

										       your system

+			keeps the content of memory across reboots before relying on this option.
+

I can send a v3.
*Grumble... :)

I haven't pushed out my tree yet, so I can replace the other one.
