This one should hopefully fix the SMP problems of the resent times.  It
works on Malta with 34K, it seems to work on IP27 (the kernel is
presumably failing due to other issues), so now I'd ask especially
RM9000 & BCM1250 users for testing.  This really needs to be fixed for
2.6.16.

I'm not sure if this is the specific fix or not, but I can report that git
as of today (approx 2pm est) is working better than is has since 2.6.14 for
me on a bcm1480. I had tried git a couple of weeks ago, and it still hung
when I stressed it.

I use NFS root, and the stress test that would hang the system is simply
"make -j 4" of the kernel. Previously this would hang the syste before
finishing.

Now that things seem to be better, I'll leave this looping for a while,
and then run some other tests. It's time to run the ltp on the 3 different
ABIs again anyway.
