[openib-general] CM patch for 2.6.17 merge

[Michael S. Tsirkin]

Roland, Sean, CM API in svn is currently richer than what we have in git.

Two parts that seem to be missing:
support for private data comparison in ib_cm_listen() and the ability to reject
requests for userspace that try to use the SDP or CMA service IDs.

The first is small and harmless if not used - I want it for things that are now
out of kernel, and to matching API API between svn and kernel.

The second is a security fix, its a must.

Sean, do you agree these two changes in CM are ready for 2.6.17?
