Subject: [PATCH] ftrace/x86: Show trampoline call function in
 enabled_functions

The file /sys/kernel/debug/tracing/eneabled_functions is used to debug
ftrace function hooks. Add to the output what function is being called
by the trampoline if the arch supports it.

Add support for this feature in x86_64.
