Re: [PATCH 5/7] rapidio: add modular build option for the subsystem core

Add a configuration option to build RapidIO subsystem core code as a loadable
kernel module. Currently this option is available only for x86-based platforms,
with the additional patch for PowerPC planned to be provided later.

This patch replaces kernel command line parameter "riohdid=" with its
module-specific analog "rapidio.hdid=".
