Hi Bart,

I got the following IDE error while trying to boot the linux-next tree

This error was bisected to the following commit:

commit fb56dbc95e05415a0c967ece13f927dd50c254bc
Author: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
Date:   Mon Apr 21 11:44:02 2008 +1000

    ide: fix hwif-s initialization

    * Add ide_hwifs[] entry initialization to ide_find_port_slot()
      and remove ide_init_port_data() calls from host drivers.

    * Unexport ide_init_port_data().

    * Remove no longer needed init_ide_data().
