+    PowerPC: Remove trailing comma in cpu_name.
+    
+    Will:
+    
+    I redid the patch as follows per your suggestions.  I was able to get
+    on to a system where the issue occurs and test the patch.  The patch
+    seems to work fine.

+    
+    The processor type for some Power 9 systems had a comma after POWER9.
+    Remove the comma before returning the string for the CPU.

+Subject: [PATCH] Initialize the trans structure fields to values unused by
+ perf samples
+
+On newer 4.14 kernel operf was crashing because the kernel commit
+1d953111b648e ("perf/core: Don't report zero PIDs for exiting tasks")
+made perf samples have TID/PID of -1 for exiting processes.  OProfile
+used this same value internally to indicate the that field had not
+been initialized.  As a result operf would incorrectly attempt to run
+some bookkeeping code due to an invalid match. The initialization of
+the trans tgid field is now changed to a value that is unsed by the
+perf samples to ensure that these invalid matches do not occur.
