    Subject[PATCH] 2.4 IDE core for 2.5

    I've forward ported the 2.4 IDE core (well 2.4.19-pre10-ac2 to be exact)
    to 2.5.25. It consists of 7 separate patches:

    Fix 2.5 IDE compilation problem with ide_fix_driveid()

    Add missing 2.4 IDE adapter pci ids

    Add 2.4 IDE core, modified for 2.5 changes

    various bits and pieces to make 2.4 IDE core work

    Split 2.4 and 2.5 IDE configuration

    allow 2.4 and 2.5 ide to be built

    Add 2.4 ide-scsi version (note that 2.5 with 2.4 ide calls it
    ide-scsi24.o currently, I'll take patches to rectify that).

    Find them all here:


    So why did I do this? Well, I needed stable IDE for 2.5 testing and it
    was/is clear that 2.5 just isn't quite there yet. I intend to maintain
    this patch set until I deem 2.5 IDE stable enough (in code) that I'm
    willing to spend time on that instead. So the life span of this patch
    depends heavily on that. That said, I know of others who would like to
    be able to test 2.5 and not having to worry too much about the
    state-of-the-day of the IDE core. This patch set may be useful to them
    as well.

    Also some notes on why I _didn't_ do this. I didn't do it because I
    think Martin is a jerk or because 2.5 IDE is forever doomed. I didn't do
    this because Andre twisted my arm. I didn't do this because of some
    hidden agenda.

    That said, the patch works for me here. I've ripped out ide-tape and
    ide-floppy (frankly, I don't think it's worth my time updating these),
    but apart from that I think it's 2.4 feature complete. PIO multi count
    breaks for multi page bio's, if you intend to use that you should change
    MPAGE_BIO_MAX_SIZE as noted in fs/mpage.c. I'll fix that in the next
