I'm curious if there a source code of SGI Numatools, which is part of proprietary package (SGI ProPack); but contain GPL code. This package consists of dlook, dplace NUMA utilities and numatools kernel module.
GPL license is listed there, in release notes of SGI ProPack: http://techpubs.sgi.com/library/dynaweb_docs/linux/usr/relnotes/sgi-propack-5-sp3-for-linux-for-amd64-em64t-for-use-with-sles10-sp1/PACKAGE_LICENSES.txt
numatools : GPL
sgi-numatools-kmp-debug : GPL
sgi-numatools-kmp-default : GPL
sgi-numatools-kmp-sltdebug : GPL
sgi-numatools-kmp-smp : GPL
sgi-numatools-kmp-xen : GPL
They used to claim that:
SGI established its intellectual alliance with Open Source years before the term was coined.

and they still provide some information about NUMA Linux support:

and a pointer to its SourceForge project:
http://lse.sourceforge.net/numa/
However the sources and information that you find in those links is not exactly up-to-date...
