b4dcaea36b Pb1200/DBAu1200: fix bad IDE resource size
The header files for the Pb1200/DBAu1200 boards have wrong definition for the
IDE interface's decoded range length -- it should be 512 bytes according to
what the IDE driver does.  In addition, the IDE platform device claims 1 byte
too many for its memory resource -- fix the platform code and the IDE driver
in accordance.

fabd3a223a Au1200: IDE driver build fix
The driver fails to compile with CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA enabled:

drivers/ide/mips/au1xxx-ide.c: In function `auide_build_dmatable':
drivers/ide/mips/au1xxx-ide.c:256: error: implicit declaration of function
`sg_virt'
drivers/ide/mips/au1xxx-ide.c:275: error: implicit declaration of function
`sg_next'
drivers/ide/mips/au1xxx-ide.c:275: warning: assignment makes pointer from
integer without a cast

Fix this by including <linux/scatterlist.h>. While at it, remove the #include's
without which the driver happily builds.

09a77441f2 Au1200: kill IDE driver function prototypes
Fix these warnings emitted when compiling drivers/ide/mips/au1xxx-ide.c:

include/asm/mach-au1x00/au1xxx_ide.h:137: warning: 'auide_tune_drive' declared 
`static' but never defined
include/asm/mach-au1x00/au1xxx_ide.h:138: warning: 'auide_tune_chipset' declared
 `static' but never defined

by wiping out the whole "function prototyping" section from the header file
<asm-mips/mach-au1x00/au1xxx_ide.h> as it mostly declared functions that are
already dead in the IDE driver; move the only useful prototype into the driver.

c976816b6e siimage: fix kernel oops on PPC 44x
Fix kernel oops due to machine check occuring in init_chipset_siimage() on PPC
44x platforms.  These 32-bit CPUs have 36-bit physical address and PCI I/O and
memory spaces are mapped beyond 4 GB; arch/ppc/ code has a fixup in ioremap()
that creates an illusion of the PCI I/O and memory resources being mapped below
4 GB, while arch/powerpc/ code got rid of this fixup with PPC 44x having instead
CONFIG_RESOURCES_64BIT=y -- this causes the resources to be truncated to 32-bit
'unsigned long' type in this driver, and so non-existant memory being ioremap'ed
and then accessed...

Thanks to Valentine Barshak for providing an initial patch and explanations.

f367bed005 Revert "ide: change master/slave IDENTIFY order"
This reverts commit b140b99c41.

[ conflict in drivers/ide/ide-probe.c fixed manually ]

It turned out that probing order change causes problems for some drives:

	http://bugzilla.kernel.org/show_bug.cgi?id=10239

Since root causes are still being investigated and are unlikely to be fixed
before 2.6.25 lets revert this change for now.  As a result cable detection
becomes less reliable when compared with 2.6.24 but the affected drives are
useable again.

6c3c3158a8 IDE: Make taskfile interface more robust wrt unexpected end-of-command
Now that we handle all the special commands using REQ_TYPE_ATA_TASKFILE
rather than using the old REQ_TYPE_ATA_CMD model, we need to also
emulate the lack of full taskfile data that comes with the old command
model (ie when commands are generated with the HDIO_DRIVE_CMD ioctl
rather than using the HDIO_DRIVE_TASK[FILE] ioctls).

In particular, this means that we should handle command completion the
more relaxed way that the old drive_cmd_intr() code did.  It allows
commands to finish early even if they don't use up all the data that we
thought we had for them.

This fixes a regression seen by Anders Eriksson where some SMART
commands sent by smartd would cause a boot-time system hang on his
machine because the IDE command handling code didn't realize that the
command had completed.

Rafael J. Wysocki
3a2d5b7001 PM: Introduce PM_EVENT_HIBERNATE callback state
During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.

But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.

For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate.  Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.

These changes are necessary to fix a hibernation regression related
to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

14e04c3f6e ide-cd: fix missing residual count setting in DMA mode
This patch fixes the missing residual count setting in DMA mode,
which was introduced during the conversion to blk-end-request.
The residual count could be used by the request submitter.
So if it isn't set correctly, some upper layers does not work.
(e.g. wodim for CD burning.)

The bug is in only DMA mode.
In PIO mode, we are setting the residual count correctly,
so no need to fix.

0e7d8d4802 ht6560b: force prefetch for some devices
Prefetch needs to be set for some ide devices to work when connected to
a ht6560b interface. This was not always done properly, causing a system
with a HD and CD on the primary interface to not work properly. Or, in
effect, hang hard.

This patch forces prefetch on devices before checking whether it
is necessary to change the settings in the interface

This patch should also be applied to 2.4. I don't currently have a
2.4 tree around.

(also change my email address)

d684b21f89 falconide: locking bugfix
commit 8ac4ce742c ("ide: fix host drivers
depending on ide_generic to probe for interfaces (take 2)") moved probing
to falconide but forgot to take care of Atari specific locking - fix it.
