We increasingly see on other architectures that people turn of 
configurable kernel features, maybe as some form of security hardening 
(threat surface reduction).  This means that code which assumes the 
presence of these kernel features (because the used to be non-optional 
and may even be mentioned in ABI documents) no longer runs. 
Consequently, you have to convince others to change their kernel 
configuration, or you have to build your software differently.

Thanks,
