I'm pretty sure this one is for Ingo and Steven to sort out, their
names are all over git-sched.patch for this code.... :)

The following config will actually build on x86_64:

CONFIG_HAVE_FTRACE=y
# CONFIG_FTRACE is not set
CONFIG_FTRACE_STARTUP_TEST=y

However, at boot time, it dies a quick and horrid ker-splat and hangs without
doing anything visible at all, without even the decency of rebooting. I'm going
to guess that the startup test fandangos on memory that wasn't set up by the
non-present CONFIG_FTRACE.

I got into this state by saying 'y' to 'startup test' in make oldconfig,
then deciding I didn't want ftrace so I turned that *one* entry off in
make menuconfig - which left the startup test dangling.  Easy local workaround
was to just turn the test off too, so you guys can hash this one out at
your leisure...
