2.5.59-mm8

[Andrew Morton]

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.59/2.5.59-mm8/

. Various tweaks and fixes, and some hugetlbpage work.

. There is an updated anticipatory scheduler patch from Nick over in
  experimental/ which addresses the large-read-starves-everything problem.

. The reworked ia32 balancing patch from Nitin Kamble is stable, and is
  consistently showing benefit for heavy networking loads on large SMP
  machines.  Even though everyone seems to agree that a userspace solution to
  this is smarter, that's no reason to hold back on improving the
  kernel-based solution so I shall be submitting that patch.

. Ingo's latest scheduler changes are here.  I held off on that because it
  appeared that there was some interaction with the I/O scheduler.  Whatever
  that was has gone away without any CPU scheduler changes, so...

. frlocks have been renamed to seqlocks, and that code is now converging
  onto something stable.

Booted to login prompt, then immediately oopsed 
(16-way NUMA-Q, mm6 worked fine). At a wild guess, I'd suspect 
irq_balance stuff.

There are a lot of scsi updates in Linus's tree.  Can you please
test just

This didn't include 4k/irqstack stuff did it?  That is in the path that
those patches touch.

<shameless plug>
A version of a proposed userspace solution can be found at
http://people.redhat.com/arjanv/irqbalance/irqbalance-0.05.tar.gz
</shameless plug>

It's still relatively simple, but it has the buildingblocks for becoming
more advanced.

Yup, the SCSI code in Linus' tree has broken since 2.5.59.
I reproduced this on my 4-way SMP machine (panic from that below), 
so it's not just NUMA-Q wierdness ;-)
