In addition, cherry-picking this fixes the build (but we haven't done a
full test with it):

commit 2750af50a360b52c6df1f5652ae728878bececc0
Author: Adrian Hunter <adrian.hunter@...el.com>
Date:   Mon Jan 24 10:41:39 2022 +0200

     perf intel-pt: pkt-decoder: Add CFE and EVD packets

Greg: Do you prefer this kind of error report go to the 0/N email (like
in this case) or to the specific problematic patch email if we've
already identified it?

Thanks,
