This patch series allows user-specified mount commands to be
sent in via kernel command line ("kinit_mount=...") or via
an embedded /etc/fstab file.
The first patch is a cleanup of a patch sent last November
by San Mehat (http://web.archiveorange.com/archive/v/EazJNBMORV2U7E0coh5h);
the next two are small improvements or bug fixes.
