Please include this patch from David Miller. Alan Cox already received
it (according to davem) and it will be in 2.2.15final. Without the
patch our two Ultra I sparc boxes didn't even survive a one minute
crashme run ;-)
So it's a crucial stability fix (at least for Ultra I cpus).

What's the railroad to me ?
I never go to see
Where it ends.
It fills a few hollows,
And makes banks for the swallows,
It sets the sand a-blowing,
And the blackberries a-growing.
(Henry David Thoreau)
Here is that patch for 2.2.15pre19
