compile error for mips with 2.6.29.2-rt10

Hello list,
I use 2.6.29.2-rt10 patch on linux-2.6.29.2 (from linux-mips.org and for bcm47xx MCU) and I had following compilation error:

kernel/sched.c: In function 'finish_task_switch':
kernel/sched.c:2902: error: implicit declaration of function '_finish_arch_switch'
make[1]: *** [kernel/sched.o] Error 1
make: *** [kernel] Error 2

When I change "_finish_arch_switch" to "finish_arch_switch" in kernel/sched.c, no compilation error, but I didn't try resulting vmlinux.

Do I miss something?

The patch is working on x86 (32 and 64bit) but we have not yet updated ARM, PPC and MIPS (work in progress).

This is still true for MIPS , but we are working on it and hopefully one of the next preempt-rt releases will have MIPS support again. Stay tuned.

Thanks,
