Subject: [PATCH 02/21] afs: Fix const confusion in AFS

From: Andi Kleen <ak@...ux.intel.com>

A trace point string cannot be const because the underlying special
section is not marked const. An LTO build complains about the
section attribute mismatch. Fix it by not marking the trace point
string in afs const.
