Subject: [for-next][PATCH 4/5] tracing: Make hash-ptr option default

From: "Steven Rostedt (VMware)" <rostedt@...dmis.org>

Since the original behavior of the trace events is to hash the %p pointers,
make that the default, and have developers have to enable the option in
order to have them unhashed.
