Fix the following similar misleading comments of ftrace for arch
ia64/metag/powerpc/sh/x86:

Note: Due to modules and __init, code can
 disappear and change, we need to protect against faulting
 as well as code changing. We do this by using the
 probe_kernel_* functions.

No real locking needed, this code is run through
kstop_machine, or before SMP starts.
