+    Only print debug message when failed to serach for kernel symbol from /proc/kallsyms
+    
+    Kernel symbol page_offset_base could be unavailable when mm KASLR code is
+    not compiled in kernel. It's inappropriate to print out error message
+    when failed to search for page_offset_base from /proc/kallsyms. Seems now
+    there is not a way to find out if mm KASLR is compiled in or not. An
+    alternative approach is only printing out debug message in get_kernel_sym
+    if failed to search a expected kernel symbol.
+    
+    Do it in this patch, a simple fix.
