They're interfaces specific to OpenSSI clustering (and Non-Stop Clusters 
for UnixWare). The rfork() and rexecve() calls allow a process to 
remotely fork and exec to another node in the cluster. The ssisys() call 
is undocumented. It serves as a single syscall number for the OpenSSI 
membership API.

Not sure you need to put these in, unless Red Hat's ready to ship 
OpenSSI clustering with Advanced Server. ;)
