Cover letter [patch 00/10] NUMA: Memoryless Node support V1

This patch is addressing various issues with NUMA as a result of memory less nodes being used. I think this is only a start fixing the most obvious things, there may be more where this came from. I'd appreciate if someone with a system with memoryless nodes could do systematic testing to see that all the NUMA functionality works properly. Nishanth has done some testing but he seems to be farily new to this.

The patchset is also part of my upload queue at
http://ftp.kernel.org/pub/linux/kernel/people/christoph/2.6.22-rc4-mm2

I know that some people are doing work based on this patchset. Will update the patches in that location if more fixes are submitted. I hope Andrew will get a new mm version out soon.
