Ravikiran G Thirumalai 556e58febf [PATCH] ide: fix kmalloc_node breakage in ide driver
Patch fixes oops caused by ide interfaces not on pci.  pcibus_to_node
causes the kernel to crash otherwise.  Patch also adds a BUG_ON to check if
hwif is NULL.

Dominik Brodowski 2b8d466937 [PATCH] pcmcia: defer ide-cs initialization after other IDE drivers started up
Avoid registering PCMCIA CF cards before other IDE stuff. This means the risk
of /dev/hd* being re-ordered is lessened. The _sane_ thing to assert any
ordering is to use udev, nameif and so on, of course.

SanDisk ConnectPlus has two functions.  Function 0 is prism2 card, currently

Jesper Juhl 77933d7276 [PATCH] clean up inline static vs static inline
`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration.  This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).

While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

Rob Punkunus recently submitted a patch to enable support for MCP51/MCP55 in

Greg Kroah-Hartman 7586585897 [PATCH] PCI: clean up dynamic pci id logic
The dynamic pci id logic has been bothering me for a while, and now that
I started to look into how to move some of this to the driver core, I
thought it was time to clean it all up.

It ends up making the code smaller, and easier to follow, and fixes a
few bugs at the same time (dynamic ids were not being matched
everywhere, and so could be missed on some call paths for new devices,
semaphore not needed to be grabbed when adding a new id and calling the
driver core, etc.)

I also renamed the function pci_match_device() to pci_match_id() as
that's what it really does.

Alan Cox da9091ee3b [PATCH] ide: it8212 backport for Bartlomiej IDE
This lets you throw out the iteraid stuff that has ended up back in due
to stupid goings on in the IDE world. Its the same heavily tested code
shipped in Fedora/Red Hat products but without the other dependancies on
the Bartlomiej IDE layer.

Pre-requisite: the ide-disk patch I sent to handle pure LBA devices.

Obviously you lose things like hot unplug with the Bartlomiej IDE layer
at the moment but that won't matter to most users.

The patch does the following
- Add IT8211/12 to pci_ids.h
- Add Makefile/Kconfig entry
- Add it8212 driver

No core IDE code is touched by this diff

The ide-generic driver gives you DMA at bios tuned speed so can actually run a

Eric Piel 9235e68be8 [PATCH] IDE CD reports current speed
The current ide-cd driver reports the CDROM speed (as found in
/proc/sys/dev/cdrom/info) as the current speed when loading the driver.
Changing the speed of the cdrom drive (by "eject -x" for instance) doesn't
update the speed reported by the kernel.  Updating the info could be
valuable for the user as it's the only way to know if the drive accepted
the request or discarded it.  It could even be used to list all the
available speeds of the drive.

The attached patch modifies the ide-cd driver so that after every speed
change request the new speed is updated.  Please note that the actual
modification is very little but I had to touch quite a few lines in order
to avoid to pre-declare the sub-functions.

Brent Casavant 22329b511a [PATCH] ioc4: Core driver rewrite
This series of patches reworks the configuration and internal structure
of the SGI IOC4 I/O controller device drivers.

These changes are motivated by several factors:

- The IOC4 chip PCI resources are of mixed use between functions (i.e.
  multiple functions are handled in the same address range, sometimes
  within the same register), muddling resource ownership and initialization
  issues.  Centralizing this ownership in a core driver is desirable.

- The IOC4 chip implements multiple functions (serial, IDE, others not
  yet implemented in the mainline kernel) but is not a multifunction
  PCI device.  In order to properly handle device addition and removal
  as well as module insertion and deletion, an intermediary IOC4-specific
  driver layer is needed to handle these operations cleanly.

- All IOC4 drivers are currently enabled by a single CONFIG value.  As
  not all systems need all IOC4 functions, it is desireable to enable
  these drivers independently.

- The current IOC4 core driver will trigger loading of all function-level
  drivers, as it makes direct calls to them.  This situation should be
  reversed (i.e. function-level drivers cause loading of core driver)
  in order to maintain a clear and least-surprise driver loading model.

- IOC4 hardware design necessitates some driver-level dependency on
  the PCI bus clock speed.  Current code assumes a 66MHz bus, but the
  speed should be autodetected and appropriate compensation taken.

This patch series effects the above changes by a newly and better designed
IOC4 core driver with which the function-level drivers can register and
deregister themselves upon module insertion/removal.  By tracking these
modules, device addition/removal is also handled properly.  PCI resource
management and ownership issues are centralized in this core driver, and
IOC4-wide configuration actions such as bus speed detection are also
handled in this core driver.

This patch:

The SGI IOC4 I/O controller chip implements multiple functions, though it is
not a multi-function PCI device.  Additionally, various PCI resources of the
IOC4 are shared by multiple hardware functions, and thus resource ownership by
driver is not clearly delineated.  Due to the current driver design, all core
and subordinate drivers must be loaded, or none, which is undesirable if not
all IOC4 hardware features are being used.

This patch reorganizes the IOC4 drivers so that the core driver provides a
subdriver registration service.  Through appropriate callbacks the subdrivers
can now handle device addition and removal, as well as module insertion and
deletion (though the IOC4 IDE driver requires further work before module
deletion will work).  The core driver now takes care of allocating PCI
resources and data which must be shared between subdrivers, to clearly
delineate module ownership of these items.

Jens Axboe 4e7c6816d6 [PATCH] Relax idecd dma alignment check
Only the address needs alignment of mask bits, length should work with
a relaxed alignment check.

Signed-off-by: Jens Axboe <axboe@suse.de>

[ This is take 2: make the length check be for 16-byte alignment, not
  just word alignment.  That should hopefully keep everybody happy,
  while still allowing CD writing with DMA ]

Marcello Maggioni 284e423811 [PATCH] timeout at boottime with NEC3500A (and possibly others) when inserted a CD in it
From: Marcello Maggioni <hayarms@gmail.com>

Problem: Some drives (NEC 3500, TDK 1616N, Mad-dog MD-16XDVD9, RICOH
MP5163DA, Memorex DVD9 drive and IO-DATA's too for sure), if a
CD/DVD is inserted into the tray when the system is booted and if
before the OS bootup the BIOS checked for the presence of a bootable
CD/DVD into the drive, during the IDE probe phase the drive may
result busy and remain so for the next 25/30 seconds . This cause the
drive to be skipped during the booting phase and not begin usable
until the next reboot (if the reboot goes well and the drive doesn't
timeout again).

Solution: Rising the timeout time from 10 seconds to 35 seconds
(during these 35 seconds every drive should wake up for sure
according to the tests I've done).

Bartlomiej Zolnierkiewicz 8604affde9 [PATCH] convert IDE device drivers to driver-model
* add ide_bus_match() and export ide_bus_type
* split ide_remove_driver_from_hwgroup() out of ide_unregister()
* move device cleanup from ide_unregister() to drive_release_dev()
* convert ide_driver_t->name to driver->name

* remove ide_driver_t->busy as ide_bus_type->subsys.rwsem
  protects against concurrent ->{probe,remove} calls
* make ide_{un}register_driver() void as it cannot fail now
* use driver_{un}register() directly, remove ide_{un}register_driver()
* use device_register() instead of ata_attach(), remove ata_attach()
* add proc_print_driver() and ide_drivers_show(), remove ide_drivers_op
* fix ide_replace_subdriver() and move it to ide-proc.c
