FWIW that diffstat looked a lot worse than it was since it was one of
these git shows as an empty diff and I used diff -c instead which
usually looks more alarming - the change was trivial code motion
deleting code in the ftrace tree with the actual fixup being very small
but in a different file.  Was a bit weird that the parameter removal
didn't go via the ftrace tree though.
