ftrace: fix hardirq.h for m68k

Ingo and Stephen,

The problem that Alexey pointed out should be fixed by this trivial patch.

The following patches are in:

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git

branch: tip/devel

Steven Rostedt (1):
ftrace: split out hardirq ftrace code into own header

i've pulled that into tip/tracing/ftrace and have pushed out a new auto-ftrace-next for Stephen - thanks Steve!

Ingo
