Greetings and Salutations,
	Sorry about the cross-post, but this patch should be of interest to both
lists.  Attatched is a copy of my implementation of the NUMA API that I would
like to see included in the mainline kernel.  The NUMA API is an API designed
to facilitate using NUMA machines.  The complete API is specified at:
http://lse.sourceforge.net/numa/numa_api.html

The patch facilitates the binding of processes to particular CPUs, groups of
CPUs, nodes, and/or memory blocks.  It also allows for a rudimentary form of
topology discovery via the xxx_to_node() and node_to_xxx() calls.  The API is
currently implemented through prctl() calls, although I do have a version that
uses syscalls instead if anyone is interested in that.

The patch is against 2.5.11, although it has only been tested on 2.5.8,
because 2.5.[9-11] do not boot on our NUMA-Q boxen.  I will be having a look
at that problem now that I've finished this.  Having looked through
changelogs, I do not see any code that would break the patch, and it applies
cleanly.  Some of the code is only useful if CONFIG_DISCONTIGMEM and/or
CONFIG_NUMA is turned on, like the memory allocation changes...

As always, questions, comments, and criticism welcome!
