    Subject[PATCH] 2.4 IDE core for 2.5
    Hi,

    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:

    00_25ide-compile-1
    Fix 2.5 IDE compilation problem with ide_fix_driveid()

    05_25pci-ids-1
    Add missing 2.4 IDE adapter pci ids

    10_24ide-core-1
    Add 2.4 IDE core, modified for 2.5 changes

    15_24-misc-bits-1
    various bits and pieces to make 2.4 IDE core work

    20_split-ide-config-1
    Split 2.4 and 2.5 IDE configuration

    25_ide-build-1
    allow 2.4 and 2.5 ide to be built

    30_ide-scsi-1
    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:

    *.kernel.org://pub/linux/kernel/people/axboe/patches/v2.5/2.5.25/

    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
    iteration.
