The patch titled
     Subject: rapidio: add modular build option for the subsystem core
has been removed from the -mm tree.  Its filename was
     rapidio-add-modular-build-option-for-the-subsystem-core.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Alexandre Bounine <alexandre.bounine@idt.com>
Subject: 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=".
