Business Case: The situation is that SGI's x86_64 platforms were just recently LSPP security certified with RHEL 5. As a result of this, a number of our DoD customers (and integrators) want to switch to RHEL, but they require all of the SGI Propack software features. Portions of the ProPack layered software were not ported to RHEL until we knew the security certification would be completed. We unfortunately overlooked that smp_call_function_single() is *not* exported on x86_64 (although it is in 2.6.20). Obviously, DoD is an important SGI customer (largest I believe). The one line patch with the export is upstream at: http://www.kernel.org/hg/index.cgi/linux-2.6/rev/f1357bacbc8b I will attach the backport to 2.6.18-86 shortly---I seem to be hitting something with git I don't understand. http://bugworks.engr.sgi.com/query.cgi/979309
