Ok Oliver, can I ask you to test one more tree?  We'll shoot for
including Ram's patches in -next, but I've just included his other
patch to disable the new realloc code by default for the current
kernel.  Can you give my for-linus tree a try and make sure it gives
you back the old behavior?  Thanks a lot for your diligent testing so
far.

git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6 is the
tree, then check out the "for-linus" branch.

Thanks,
