 * Parse the command-line parameters given our kernel, but do not

 *

 * 27/11/1999: Fixed to work correctly with the 2.3 kernel (which

 *             assigns the task of parsing integer arguments to the

 *             invoked program now).  Added ability to initialise all

 *             the MD devices (by specifying multiple "md=" lines)

 *             instead of just one.  -- KTK

 * 18May2000: Added support for persistent-superblock arrays:

 *             md=n,0,factor,fault,device-list   uses RAID0 for device n

 *             md=n,-1,factor,fault,device-list  uses LINEAR for device n

 *             md=n,device-list      reads a RAID superblock from the devices

 *             elements in device-list are read by name_to_kdev_t so can be

 *             a hex number or something like /dev/hda1 /dev/sdb

 * 2001-06-03: Dave Cinege <dcinege@psychosis.com>

 *      Shifted name_to_kdev_t() and related operations to md_set_drive()

 *      for later execution. Rewrote section to make devfs compatible.
