That should be probably improved later.
(btw I just fixed stacking there, it was written by Andi Kleen).
Anyway, now I need to check that there is no known data corruption
with this approach and then we can add another patches on top of it.
(Targeted for 2.6.38, it missed 2.6.37 merge window already.)
(If anyone see some reproducible data corruption when using this patch,
please let me know.)
