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.

9ea244b4b5 [PATCH] RocketPoint 1520 [hpt366] fails clock stabilization
I just purchased a HighPoint Rocket 1520 SATA controller.  There seems to
be no libata driver (yet), but there is an ide driver, hpt366.  When the
driver gets loaded, it causes a kernel NULL pointer dereference in
pci_bus_clock_list.  It seems to be because the driver is waiting for clock
stabilization in init_hpt37x() which never comes.  The driver just
continues on with the pci drvdata set to NULL, instead of a valid clock
entry.  The following patch prevents the NULL dereference from happening,
but instead exit with an error.

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.

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.

* Any failure of pre or post flush request results in failure

for fs requests, this doesn't really matter, so just using the

help the generic command-carrying request jens is working on.

Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified

probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

98e4c28b7e [PATCH] pcmcia: new suspend core
Move the suspend and resume methods out of the event handler, and into
special functions. Also use these functions for pre- and post-reset, as
almost all drivers already do, and the remaining ones can easily be
converted.

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

8f29e650bf [PATCH] ide: AU1200 IDE update
Changes here include removing all of CONFIG_PM while it is being repeatedly
smacked with a lead pipe, moving the BURSTMODE param to a #define (it should
be defined almost always anyway), fixing the rqsize stuff, pulling ide_ioreg_t,
and general cleanups and whatnot.
