[PATCH] Building list of drives in right order

	ata_attach in linux-2.5.34/drivers/ide/ide.c builds a list of
IDE drives that do not yet have a device driver bound to them, in case
ide-disk, ide-scsi, or whatever driver you want to use is not loaded
yet.

	The problem was that ata_attach was adding to the head of
the list, so the list was being built in reverse order.  So, if
you had two IDE disks, and ide-disk was a loadable module, the
devfs entries for the disks would be numbered in reverse (the
first disk would be /dev/discs/disc1, and the second would be
/dev/discs/disc0).

	This fixes the problem by changing the relevant list_add to
list_add_tail.  Incidentally, the generic code in drivers/base/ already
does it this way.
