Except what does the "entry" part mean?

Traditionally entry.S has been for the code that "enters" the kernel,
ie. from userspace or elsewhere. But that's not the case with any of the
ftrace code, it's kernel code called from the kernel. So using "entry"
is a bit wrong IMHO.

So if we drop that we're left with ftrace.S - which seems perfect to me.
