Changes since 2.6.25.4-rt5

  - sched_cpupri hotplug support (Gregory Haskins)

  - sched_cpupri prio count (Gregory Haskins)

  - ftrace hotplug fix (Steven Rostedt)

to build a 2.6.25.4-rt6 tree, the following patches should be applied:

I got this error message at compile stage. Also it is the same error 
that was on -rt4. -rt3 compiles and runs fine.
