- Propagate the queue handling changes to pmac as well.

- Move set_transfer to ide-taskfile.c this is the only place where it's used
   and it can be made static there. Same applies to ide_ata66_check().

- Move ide_auto_reduce_xfer to ide.c.

- Make ide_cmd() local to the only place where it's used. Rename it to
   drive_cmd(). Don't pass drive_cmd_intr() as parameter.

- Remove ide_next command completion type. Nobody is using it.

- Move ide_do_drive_cmd to ide-taskfile. It's used there and in sub-drivers.
   Not in ide.c. The usage inside the device type drivers is entirely bogus
   inconsistent and so on...

- Kill bogus IRQ masking code. The kernel is supposed to handle this properly.
   We should not try to work against possible bugs in the overall irq handling
   code. Wow this is increasing the systems overall responsibility by a
   significant margin.

- Remove disfunctional pdcadma code. It is only misleading to the user.

- Streamline device detection reporting to always use ->slot_name.

- Apply 64 bit sector size fixes to the overall code.

- Push ->handler down to the struct ata_channel.

- Introduce channel group based locking instead of a single global lock for all
   operations. There are still some places where we have preserved the ide_lock.
   We can't lock for queues during device probe and we protect global data
   structures during device registration and unregistration in ide.c with it.

- Start replacement of serialized access to the registers of
   channels which share them with proper host chip driver specific locking.
   This affects the following host chip drivers:

   cmd640.c, rz1000, ... ?

   Seems some are setting the serialize flag just in case. So better let's do it
   gradually over time.

   Well, I still have to think whatever we really need to put channels sharing
   an IRQ line in the same locking group.

   From now on the sick concept of a hw group is gone now. We have full blown
   per channel request queues! Hopefully I will be able soon to get my hands on
   a dual Athlon machine to check how this all behaves on a multi SMP machine.

- Move the whole SUPPORT_VLB_SYNC stuff to the only place where it is used: the
   pdc4030 host chip driver.  Eliminate it from the global driver part.

- Eliminate pseudo portability macros from pdc4030. This is a host chip firmly
   based on VLB.

- Fix typo in pdc202xx driver.

- Fix locking order in ioctl.

- Fix wrong time_after usage introduced in 60. Maybe the fact I always get is
   wrong is related to the fact that I'm using the mouse with the left hand!?

- Apply arch-clean-2 by Bartlomiej Zolnierkiewicz.

- Don't disable interrupts during ide_wait_stat(). I see no reason too.

- Push flags down from hwgroup to the ata_chaannel structure.

- Apply small fixes from Franz Sirl to make AEC6280 working properly again.

This patch further cleans up and separates the code in an effort to
allow setting (a) a larger maximum real-time priority than default and
(b) a maximum kernel RT priority that is separate than the maximum
priority exported to user-space.

Special thanks to Intel for support and traces.

- Commented out the usb-ohci driver.  This is part of the migration away from
  this driver, to the ohci-hcd driver.
- Prevented the two UHCI_HCD drivers from both being compiled into the kernel
  at the same time.

This removes a compiler warning due to my previous patch.

fixed up the Config.in and Makefile merge due to there being 2 uhci-hcd drivers added at once.

After maturing for more than a month, I decided that it's enough...
So here's the patch for the HCD-version of usb-uhci, I called it
usb-uhci-hcd. For me, the usual devices work (TM).

Since the internals haven't changed much, I don't expect much difference to
usb-uhci in functionality and performance.

There is one major improvement: I've added a (preliminary) watchdog, that
regularly checks whether UHCI interrupts are coming through. If they are
"missing", ie. the HC halted without saying so, the HC is "re-animated" by a
real and clean restart, which is (internally) equivalent to a module-reload.
This is especially for VIA-chips which get comatose quite easily by babble
or other incorrect transfers.

The side effect is, of course, disconnects for all connected devices, but
they re-appear after a few seconds and were dead before anyway. So keyboard
and mouse work again, which is IMO a _very_ useful thing :-)

Another point: The watchdog (currently with moderate 8 interrupts/s) detects
IRQ-problems, so the misleading "device doesn't accept new device"-message
is replaced by an immediate error.

More comments and the separation into multiple files (I've taken ohci-hcd as
an example) should make the code more concise...

A few things are still on the todo-list and will come later:
- A few watchdog modifications (fewer interrupts, better diagnostics)
- Support for module "tune"-parameters for breadth/depth search, debug etc.
- interval support for ISO
- More SMP-tests
- maybe changes for reference counting when it is clear what survives :-)

Based on a patch from Georg Acher <georg@acher.org>

Woops, I sent the wrong version. There was one extra line that was
required.

This fixes up a couple of problems I came across while working on
uhci-hcd. There are a couple of places where shifts are used where they
shouldn't be and others where should be.

This cleans up a couple of cases and tidys it up.

The patch is relative to 2.4.19-pre8 and my other patches, but it's
alright to wait for 2.4.20. It should also be applied to 2.5.

So I finally hunkered down and got uhci-hcd working. I was surprised how
easy it was to make the modifications for hcd.c.

This patch has received a moderate amount of testing so far. I've played
with various devices and haven't had any problems. I won't claim it's
bug free yet and I'll continue doing more testing.

The patch includes a small change to hcd.c to not call free_config if
the HCD doesn't implement it.

There are some other messages that get printed such as:

hcd.c: usb_hcd_pci_remove 00:10.0, count != 1

but it appears from the code that this is just a soft warning that all
of the references to the bus aren't freed yet. This isn't a bug.

Differences from usb-uhci/usb-uhci-hcd:
- Cleaner code. uhci-hcd is based off of uhci, so it maintains the same
  look and feel as well as readability.
- Faster. The tests I've run so far show that uhci-hcd is faster in
  every case than usb-uhci-hcd
- It does not have the watchdog type feature for VIA chipsets. It's
  something that is definately possible to implement, but I'd like to
  find out what Windows does first.

Differences from uhci:
- Modified to use the hcd.c framework. This removed a significant amount
  of code and nesessitated lots of little changes.
- Big endian support. I haven't been able to test it on a big endian
  machine yet, but atleast 90+% of the work should be done. Once I get
  my PowerPC working again, I'll test this and submit any appropriate
  patches. This was the biggest functional change between uhci.c.
- No more urb->next processing. Completely ripped out.
- urb->interval support for Isochronous pipes.
- A couple of bug fixes for some problems I noticed while working on the
  code. These will be submitted for uhci.c in a seperate email.

This was forgotten in the previous sddr55 patch import, and is needed
to support the MDSM-B reader devices.

Thanks to Andries.Brouwer@cwi.nl for the 2.4.x version of the patch.

This bug, introduced by the fix for ppp_deflate, makes zisofs unhappy
with certain input.

This patch replaces the awkwardly named usb_inc_dev_use() and
usb_dec_dev_use() with usb_get_dev() and usb_put_dev() to match the
naming convention of the rest of the kernel's reference counted
structures.  It also does away with the special case of usb_free_dev(),
and has usb_put_dev() be the same thing (through a #define, just like
usb_free_urb() works.)

Now when the last person calls usb_put_dev() or usb_free_dev() the
structure is cleaned up.  This allows the different host controller
drivers to implement their logic differently if they want to (as they
do), and everyone can be happy and stop arguing about the "proper" way
to write their host controller drivers :)

Earlier in the 2.5 development cycle a patch was applied that changed
the reference counting behaviour for USB devices.

There are a couple of problems with the change:
- It made the USB code more complicated as a whole with the introduction
  of an additional cleanup path for devices. Using the traditional method
  of reference counting, cleanup is handled implictly
- It reduces functionality by requiring a callback for all references to
  the device, but doesn't provide a method of providing callbacks for
  references. It relies on the hardcoded device driver ->disconnect and
  HCD ->deallocate method for callbacks

The traditional method of using reference counting supports as many
reference users as needed, without complicating it with mandatory
callbacks to cleanup references.

The change in 2.5 also only helps catch one subset of programming
problem in device drivers, the case where it decrements too many times.
That is of dubious debugging value.

So, this patch reverts the change and makes the reference counting
behave like it does in the rest of the kernel as well as how the USB
code does in 2.4.

This patch doesn't remove all of the superfluous code. Some drivers,
like usb-ohci, ohci-hcd and ehci-hcd have some code that is no longer
needed. I wanted to spend some more time with those drivers since the
changes weren't as trivial as uhci.c and usb-uhci.c.

I've tested with uhci and usb-ohci with no adverse effects.

added check for wMaxPacketSize of 0, which is a messed up device, but
seems to be legal according to the USB spec.

Thanks to Johannes for figuring out the problem, and providing an
original version of this patch.

I found several SMP and UP locking errors in usb-storage, attached is a
patch:

Changes:
* srb->result is a bitfield, several << 1 were missing.
* add scsi_lock calls around midlayer calls, release the lock before
  calling usb functions that might sleep.
* replace the queue semaphore with a queue spinlocks, queuecommand is
  called from bh context.

This changes do_fork() to return the task struct, rather than the PID.

Also changes CLONE_PID ("if my pid is 0, copy it") to CLONE_IDLETASK
("set child's pid to zero"), and disallows access to the flag from user
mode.

Fixes lockup on SMP boxes, and fixes buggy map scanning code.

we fix ARM720T support - this CPU has unified writethrough caches
only, so we can't use the Harvard cache operations when copying
pages.  Also, we don't have to evict cache entries during copypage.

Use the standard new-style pci_driver::remove to unregister
drivers at module unload time.

PCMCIA obviously has its own way of handling removing, the ISA
drivers unregister at module unload time as well.

Don't use a special CAPI solution to tell the drivers about 
ISA cards but use module parameters, just as other drivers do.

Internally use struct pci_dev to save that data - hopefully
one day the device tree will provide a nicer way to achieve this.

Use common function for setting the revision strings.

We now control rely on ->owner and the upper level to control the
module use count.
