Kumar Gala 208a08f7cc [PATCH] ide: Allow IDE interface to specify its not capable of 32-bit operations
In some embedded systems the IDE hardware interface may only support 16-bit
or smaller accesses.  Allow the interface to specify if this is the case
and don't allow the drive or user to override the setting.

Michael Richardson c2f8311d31 [PATCH] ide: cast arguments to pr_debug() properly
This does not show up unless you #define DEBUG in the file, which most
people wouldn't do.  On PPC405, at least, "sector_t" is unsigned long,
which doesn't match %llx/%llu.  Since sector# may well be >32 bits, promote
the value to match the format.

Richard Purdie 9810933701 [PATCH] stop CompactFlash devices being marked as removable
This patch stops CompactFlash devices being marked as removable.  They are
not removable (as defined by Linux) as the media and device are
inseparable.  When a card is removed, the whole device is removed from the
system and never sits in a media-less state.

This stops some nasty udev device creation/destruction loops.

Further, once this change is made, there is no need for ide to can be
removed from ide_drive_t.

Christoph Hellwig a885c8c431 [PATCH] Add block_device_operations.getgeo block device method
HDIO_GETGEO is implemented in most block drivers, and all of them have to
duplicate the code to copy the structure to userspace, as well as getting
the start sector.  This patch moves that to common code [1] and adds a
->getgeo method to fill out the raw kernel hd_geometry structure.  For many
drivers this means ->ioctl can go away now.

[1] the s390 block drivers are odd in this respect.  xpram sets ->start
    to 4 always which seems more than odd, and the dasd driver shifts
    the start offset around, probably because of it's non-standard
    sector size.

Tejun Heo 3e087b5754 [BLOCK] update IDE to use new blk_ordered for barriers
Update IDE to use new blk_ordered.  This change makes the
following behavior changes.

* Partial completion of the barrier request is handled as
  failure of the whole ordered sequence.  No more partial
  completion for barrier requests.

* Any failure of pre or post flush request results in failure
  of the whole ordered sequence.

So, successfully completed ordered sequence guarantees that
all requests prior to the barrier made to physical medium and,
then, the while barrier request made to the physical medium.

Kay Sievers 263756ec22 [PATCH] ide: MODALIAS support for autoloading of ide-cd, ide-disk, ...
IDE: MODALIAS support for autoloading of ide-cd, ide-disk, ...

Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and
ide-tape, to autoload these modules depending on the probed media type of
the IDE device.

It is used by udev and replaces the former agent shell script of the hotplug
package, which was required to lookup the media type in the proc filesystem.
Using proc was racy, cause the media file is created after the hotplug event
is sent out.

The module autoloading does not take any effect, until something like the
following udev rule is configured:
  SUBSYSTEM=="ide",  ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}"

The module ide-scsi will not be autoloaded, cause it requires manual
configuration. It can't be, and never was supported for automatic setup in
the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported
media types, would just lead to a default blacklist entry anyway.

  $ modinfo ide-disk
  filename:       /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko
  description:    ATA DISK Driver
  alias:          ide:*m-disk*
  license:        GPL
  ...

  $ modprobe -vn ide:m-disk
  insmod /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko

  $ cat /sys/bus/ide/devices/0.0/modalias
  ide:m-disk

It also adds attributes to the IDE device:
  $ tree /sys/bus/ide/devices/0.0/
  /sys/bus/ide/devices/0.0/
  |-- bus -> ../../../../../../../bus/ide
  |-- drivename
  |-- media
  |-- modalias
  |-- power
  |   |-- state
  |   `-- wakeup
  `-- uevent

  $ cat /sys/bus/ide/devices/0.0/{modalias,drivename,media}
  ide:m-disk
  hda
  disk

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
