Subject[PATCH 2/3] [PATCH 2/3] tracing: switch function prints from %pf to %ps
From: Steven Rostedt <srostedt@redhat.com>

For direct function pointers (like what mcount provides) PowerPC64
requires the use of %ps, otherwise nothing is printed.

This patch converts all prints of functions retrieved through mcount
to use the %ps format from the %pf.
