SubjectRe: 2.6.25.8-rt7
(Sorry for toppost)

I believe this is my fault. You must be building for uniprocessor? Ingo has a fix for this issue in sched-devel that should be pulled into -rt.

Sorry for the inconvenience. I will pull the patch myself and submit it when I get home (if someone doesn't beat me to it)

This occurs when I try to build a PowerPC (MPC5200) kernel:

[...]
In file included from kernel/sched.c:1318:
kernel/sched.c: In function 'sched_init':
kernel/sched.c:7702: error: implicit declaration of function 'global_rt_runtime'
[...]

And when I'm using the patch from Uli Brueggemann to fix it, I get:

[...]
In file included from kernel/sched.c:1325:
kernel/sched_rt.c: In function 'inc_rt_tasks':
kernel/sched_rt.c:290: error: 'struct rq' has no member named 'online'
[...]

Any hints?
