+    Fix Cavium Thunder X2 build issues
+    
+    Release v4.10.0 had a few bugs related to Cavium Thunder X2 build.
+    
+    - lib/Makefile dependency was pointing to the wrong Cavium Thunder X2 event file name
+    - lib/Makefile was missing Cavium event file dependency for ARM64
+    - lib/pfmlib_commmon.c was missing support for Cavium Thunder X2 in 32-bit mode
