I've rebased on top of 3.10, and manually ported all changes to kernel/sched.c (in 3.0) forward to 3.10 (in kernel/sched/core.c, etc.).

The resulting kernel contains now all major bits of LITMUS^RT and even compiles. However, I can't get it to boot yet in my version of Qemu due to some stupid APIC emulation issues that are unrelated to LITMUS^RT.

Anyway, if anyone has some spare cycles, please try booting the 3.10 version and note what breaks.

(NB: liblitmus doesn't compile yet against the new kernel…)

Thanks,
Björn
