Support needs to be there before anyone can use it :)

Here is a git tree of our atomics work so far:
http://www.openfabrics.org/git/?p=~agrover/ofed_1_5/linux-2.6.git;a=shortlog;h=future/20100203

Still in-development, but it should be ready very soon. We will be the
first in-kernel user of atomics, as well as masked atomics. This tree
does not support masked atomics yet because it is based on ofed 1.5.1.
When 1.5.2 is officially released, I'll rebase, add mask support, and
plan on pushing to mainline and ofed 1.6 as soon as it opens.
