Pete Zaitcev c36fc889b5 [PATCH] usb: Patch for USBDEVFS_IOCTL from 32-bit programs
Dell supplied me with the following test:

#include<stdio.h>
#include<errno.h>
#include<sys/ioctl.h>
#include<fcntl.h>
#include<linux/usbdevice_fs.h>

main(int argc,char*argv[])
{
   struct usbdevfs_hub_portinfo hubPortInfo = {0};
   struct usbdevfs_ioctl command = {0};
   command.ifno = 0;
   command.ioctl_code = USBDEVFS_HUB_PORTINFO;
   command.data = (void*)&hubPortInfo;
   int fd, ret;
   if(argc != 2) {
     fprintf(stderr,"Usage: %s /proc/bus/usb/<BusNo>/<HubID>\n",argv[0]);
     fprintf(stderr,"Example: %s /proc/bus/usb/001/001\n",argv[0]);
     exit(1);
   }
   errno = 0;
   fd = open(argv[1],O_RDWR);
   if(fd < 0) {
     perror("open failed:");
     exit(errno);
   }
   errno = 0;
   ret = ioctl(fd,USBDEVFS_IOCTL,&command);
   printf("IOCTL return status:%d\n",ret);
   if(ret<0) {
     perror("IOCTL failed:");
     close(fd);
     exit(3);
   } else {
       printf("IOCTL passed:Num of ports %d\n",hubPortInfo.nports);
       close(fd);
       exit(0);
   }
   return 0;
}

I have verified that it breaks if built in 32 bit mode on x86_64 and that
the patch below fixes it.

Juha Yrj?l? 4e67185a7a [PATCH] add usb transceiver set_suspend() method
When a USB device is put into suspend mode, the current drawn from VBUS
has to be less than 500 uA. Some transceivers need to be put into a
special power-saving mode to accomplish this, and won't have a separate
OTG driver handling that.

This adds a suspend method to the "otg_transceiver" struct -- misnamed,
it's not only for OTG -- and calls it from the OMAP UDC driver.

This patch resolves that issue by checking the relevant bit and adjusting

morph into an illegal 14 byte one any more.

Alan Stern b81d34363c [PATCH] UHCI: Improve handling of iso TDs
The uhci-hcd driver is fairly lax about the way it handles isochronous
transfers.  This patch (as579) improves it in three respects:

	TDs for a new URB aren't added to the schedule until all of
	them have been allocated.  This way there's no risk of the
	controller executing some of them when an allocation fails.

	TDs for an unlinked URB are removed from the schedule as soon
	as the URB is unlinked, rather than waiting until the URB is
	given back.  This way there's no risk of the controller still
	executing a TD after the URB completes.

	The urb->error_count values are now reported correctly.
	Although since they aren't used in any drivers except for
	debug messages in the system log, probably nobody cares.

Alan Stern 0c0382e32d [PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspend
This patch (as580) is perhaps the only result from the long discussion I
had with David about his changes to the root-hub suspend/resume code.  It
renames the hub_suspend and hub_resume methods in struct usb_hcd to
bus_suspend and bus_resume.  These are more descriptive names, since the
methods really do suspend or resume an entire USB bus, and less likely to
be confused with the hub_suspend and hub_resume routines in hub.c.

It also takes David's advice about removing the layer of bus glue, where
those methods are called.  And it implements a related change that David
made to the other HCDs but forgot to put into dummy_hcd.

Daniel Drake a8798533c1 [PATCH] USB Storage: HP8200: Another device type detection fix
There appears to be one more case where the HP8200 CD writer devices are
detected as flash readers - when the USB cable is replugged after use, with
the power cable still connected.

Oddly enough, the identify device command appears to 'fall through' when the
devices are in this state, the status register reading exactly the same opcode
as the command (0xA1) that was just executed.

I think it's safe to label this behaviour as specific to HP8200 devices, I
can't get the flash devices to respond like this.

This patch should solve the last of the HP8200 issues which have cropped up
recently.

Alan Stern d09d36a91c [PATCH] USB: usb_bulk_message() handles interrupts endpoints
Because there is no bulk_interrupt_message() routine and no
USBDEVFS_INTERRUPT ioctl, people have been forced to abuse the
usb_bulk_message() routine and USBDEVFS_BULK by using them for interrupt
transfers as well as bulk transfers.

This patch (as567) formalizes this practice and adds code to
usb_bulk_message() for detecting when the target is really an interrupt
endpoint.  If it is, the routine submits an interrupt URB (using the
default interval) instead of a bulk URB.  In theory this should help HCDs
that don't like it when people try to mix transfer types, queuing both
periodic and non-periodic types for the same endpoint.

Not fully tested -- I don't have any programs that use USBDEVFS_BULK for
interrupt transfers -- but it compiles okay and normal bulk messages work
as well as before.

  - Ignoring that handoff on HPPA;

The diagnostic string is mostly shared with EHCI, saving a few bytes.

David Brownell f197b2c54b [PATCH] OHCI PM updates
This simplifies the OHCI root hub suspend logic:

 - Uses new usbcore root hub calls to make autosuspend work again:
	* Uses a newish usbcore root hub wakeup mechanism,
	  making requests to khubd not keventd.
	* Uses an even newer sibling suspend hook.

 - Expect someone always made usbcore call ohci_hub_suspend() before bus
   glue fires; and that ohci_hub_resume() is only called after that bus
   glue ran.  Previously, only CONFIG_USB_SUSPEND promised those things.
   (Includes updates to PCI and OMAP bus glue.)

 - Handle a not-noticed-before special case during resume from one of
   the swsusp snapshots when using "usb-handoff":  the controller isn't
   left in RESET state.  (A bug to fix in the usb-handoff code...)

Also cleans up a minor debug printk glitch, and switches an mdelay over
to an msleep (how did that stick around for so long?).

David Brownell 5f827ea3c3 [PATCH] usbcore PCI glue updates for PM
This updates the PCI glue to address the new and simplified usbcore suspend
semantics, where CONFIG_USB_SUSPEND becomes irrelevant to HCDs because
hcd->hub_suspend() will always be called.

  - Removes now-unneeded recursion support

  - Go back to ignoring faults reported by the wakeup calls; we expect them
    to fail sometimes, and that's just fine.

The PCI HCDs will need simple changes to catch up to this, like being able
to ignore the setting of CONFIG_USB_SUSPEND.

David Brownell f3f3253d64 [PATCH] root hub updates (greater half)
This patch associates hub suspend and resume logic (including for root hubs)
with CONFIG_PM -- instead of CONFIG_USB_SUSPEND as before -- thereby unifying
two troublesome versions of suspend logic into just one.  It'll be easier to
keep things right from now on.

  - Now usbcore _always_ calls hcd->hub_suspend as needed, instead of
    only when USB_SUSPEND is enabled:
     * Those root hub methods are now called from hub suspend/resume;
       no more skipping between layers during device suspend/resume;
     * It now handles cases allowed by sysfs or autosuspended root hubs,
       by forcing the hub interface to resume too.

  - All devices, including virtual root hubs, now get the same treatment
    on their resume paths ... including re-activating all their interfaces.

Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and
updates the Kconfig to match the new definition of USB_SUSPEND:  it provides
(a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream
from any device configuration which supports it.

This calls for minor followup patches for most HCDs (and their PCI glue).

David Brownell 979d5199fe [PATCH] root hub changes (lesser half)
This patch collects various small updates related to root hubs, to shrink
later patches which build on them.

  - For root hub suspend/resume support:
     * Make the existing usb_hcd_resume_root_hub() routine respect pmcore
       locking, exporting and using the dpm_runtime_resume() method.
     * Add a new usb_hcd_suspend_root_hub() to pair with that routine.
       (Essential to make OHCI autosuspend behave again...)
     * HC_SUSPENDED by itself only refers to the root hub's downstream ports.
       So let HCDs see root hub URBs unless the parent device is suspended.

  - Remove an assertion we no longer need (and now, also don't want).

  - Generic suspend/resume updates to work better with swsusp.
     * Ignore the FREEZE vs SUSPEND distinction for hardware; trying to
       use it breaks the swsusp snapshots it's supposed to help (sigh).
     * On resume, mark devices as resumed right away, but then
       do nothing else if the device is marked NOTATTACHED.

These changes shouldn't be very noticable by themselves.

suspend routines just like on the PCI "USB_SUSPEND not defined" cases,

David Brownell 390a8c345e [PATCH] remove usb_suspend_device() parameter
This patch removes the extra usb_suspend_device() parameter.  The original
reason to pass that parameter was so that this routine could suspend any
active children.  A previous patch removed that functionality ... leaving
no reason to pass the parameter.  A close analogy is pci_set_power_state,
which doesn't need a pm_message_t either.

On the internal code path that comes through the driver model, the parameter
is now used to distinguish cases where USB devices need to "freeze" but not
suspend.   It also checks for an error case that's accessible through sysfs:
attempting to suspend a device before its interfaces (or for hubs, ports).

David Brownell c9f89fa40c [PATCH] remove suspend-path recursion
This patch removes some recursion in the CONFIG_USB_SUSPEND logic, which
suspended children (of devices or hubs) that weren't already suspended.
When it sees such cases, suspend now just fails cleanly.

That logic was not needed during system-wide sleep state transitions; and
given the current notions of how to manage selective suspend transitions,
we don't want it there either.  Where it was particularly handy was coping
with various limitations of the sysfs "echo -n N > power/state" support.
(These include assuming that "N" is always meaningful to the driver; and
that drivers can only transition to state N from state zero.)

David Brownell db69087437 [PATCH] usb_interface power state
This updates the handling of power state for USB interfaces.

  - Formalizes an existing invariant:  interface "power state" is a boolean:
    ON when I/O is allowed, and FREEZE otherwise.  It does so by defining
    some inlined helpers, then using them.

  - Adds a useful invariant:  the only interfaces marked active are those
    bound to non-suspended drivers.  Later patches build on this invariant.

  - Simplifies the interface driver API (and removes some error paths) by
    removing the requirement that they record power state changes during
    suspend and resume callbacks.  Now usbcore does that.

A few drivers were simplified to address that last change.

The latest kernel added a pretty ugly fix for the orinoco etherleak bug
which contains bogus skb->len checks already done by the caller and causes
copies of all odd sized frames (which are quite common)

While the skb->len check should be ripped out the other fix is harder to do
properly so I'm proposing for this the -mm tree only until next 2.6.x so
that it gets tested.

Instead of copying buffers around blindly this code implements a padding
aware version of the hermes buffer writing function which does padding as
the buffer is loaded and thus more cleanly and without bogus 1.5K copies.

Reduce the SHPC hotplug driver's dependence on ACPI. We don't
walk the acpi namespace anymore to build a list of bridges and

_OSHP method to transition control of hotplug hardware from
system BIOS to the shpc hotplug driver, and to run the _HPP
method to get hotplug device parameters like cache line size,
latency timer and SERR/PERR enable from BIOS.

Note that one of the side effects of this patch is that shpchp
does not enable the hot-added device or its DMA bus mastering
automatically now. It expects the device driver to do that.
This may break some drivers and we will have to fix them as
they are reported.

IPR scsi adapter have an exposure today in that they issue BIST to the adapter
to reset the card.  If, during the time it takes to complete BIST, userspace
attempts to access PCI config space, the host bus bridge will master abort the
access since the ipr adapter does not respond on the PCI bus for a brief
period of time when running BIST.  On PPC64 hardware, this master abort
results in the host PCI bridge isolating that PCI device from the rest of the
system, making the device unusable until Linux is rebooted.  This patch makes
use of some newly added PCI layer APIs that allow for protection from
userspace accessing config space of a device in scenarios such as this.

blocking code in the PCI code.  When blocked, writes will be humored and reads
will return the cached value.  Ben Herrenschmidt has also mentioned that he
plans to use this in PPC power management.

Jean Delvare 421ef47be2 [PATCH] i2c: SMBus PEC support rewrite, 2 of 3
This is my rewrite of the SMBus PEC support. The original
implementation was known to have bugs (credits go to Hideki Iwamoto
for reporting many of them recently), and was incomplete due to a
conceptual limitation.

The rewrite affects only software PEC. Hardware PEC needs very little
code and is mostly untouched.

Technically, both implementations differ in that the original one
was emulating PEC in software by modifying the contents of an
i2c_smbus_data union (changing the transaction to a different type),
while the new one works one level lower, on i2c_msg structures (working
on message contents). Due to the definition of the i2c_smbus_data union,
not all SMBus transactions could be handled (at least not without
changing the definition of this union, which would break user-space
compatibility), and those which could had to be implemented
individually. At the opposite, adding PEC to an i2c_msg structure
can be done on any SMBus transaction with common code.

Advantages of the new implementation:

* It's about twice as small (from ~136 lines before to ~70 now, only
  counting i2c-core, including blank and comment lines). The memory
  used by i2c-core is down by ~640 bytes (~3.5%).

* Easier to validate, less tricky code. The code being common to all
  transactions by design, the risk that a bug can stay uncovered is
  lower.

* All SMBus transactions have PEC support in I2C emulation mode
  (providing the non-PEC transaction is also implemented). Transactions
  which have no emulation code right now will get PEC support for free
  when they finally get implemented.

* Allows for code simplifications in header files and bus drivers
  (patch follows).

Drawbacks (I guess there had to be at least one):

* PEC emulation for non-PEC capable non-I2C SMBus masters was dropped.
  It was based on SMBus tricks and doesn't quite fit in the new design.
  I don't think it's really a problem, as the benefit was certainly
  not worth the additional complexity, but it's only fair that I at
  least mention it.

Lastly, let's note that the new implementation does slightly affect
compatibility (both in kernel and user-space), but doesn't actually
break it. Some defines will be dropped, but the code can always be
changed in a way that will work with both the old and the new
implementations. It shouldn't be a problem as there doesn't seem to be
many users of SMBus PEC to date anyway.

__iomem/iowrite8/ioread8 functions to abstract the direct or
memory-mapped variants of register access.  Also, the original driver
would crash on module load on the Alpha because the PCI memory region
was not remapped into kernel memory.

I have managed the following testing:

* compiled and tested it on my Alpha UP2000+ system.
* compiles cleanly for x86 but I don't have the hardware to test.

I2C_SMBUS_I2C_BLOCK_MAX has always been defined to the same value as
I2C_SMBUS_BLOCK_MAX, and this will never change: setting it to a lower
value would make no sense, setting it to a higher value would break
i2c_smbus_data compatibility. There is no point in changing
i2c_smbus_data to support larger block transactions in SMBus mode, as
no SMBus hardware supports more than 32 byte blocks. Thus, for larger
transactions, direct I2C transfers are the way to go.

Petr Vandrovec ada0c2f8fa [PATCH] hwmon: Fix w83627ehf/hf vs PNPACPI conflict (bug #4014)
This patch changes w83627hf and w83627ehf drivers to reserve only ports
0x295-0x296, instead of full 0x290-0x297 range.  While some other
sensors chips respond to all addresses in 0x290-0x297 range, Winbond
chips respond to 0x295-0x296 only (this behavior is implied by
documentation, and matches behavior observed on real systems).  This is
not problem alone, as no BIOS was found to put something at these unused
addresses, and sensors chip itself provides nothing there as well.

But in addition to only respond to these two addresses, also BIOS
vendors report in their ACPI-PnP structures that there is some resource
at I/O address 0x295 of length 2.  And when later this hwmon driver
attempts to request region with base 0x290/length 8, it fails as one
request_region cannot span more than one device.

Due to this we have to ask only for region this hardware really
occupies, otherwise driver cannot be loaded on systems with ACPI-PnP
enabled.

small driver so the benefit is thin, but still worth it.

Jean Delvare d6072f842a [PATCH] i2c: Reuse name strings in i2c bus drivers
Clean up name string usage in 12 i2c bus drivers:
* Use the i2c_adapter name for requesting the I/O region rather than
  redefining a new string.
* Do not initialize the i2c_adapter name to "unset".
This should save a few data bytes here and there.

Eugene Surovegin 37448f7d39 [PATCH] New PowerPC 4xx on-chip ethernet controller driver
This patch replaces current PowerPC 4xx EMAC driver with
new, re-written from the scratch version. This patch is quite big
(~234K) because there is virtualy 0% of common code between old and
new version.

New driver uses NAPI, it solves stability problems under heavy packet
load and low memory, corrects chip register access and fixes numerous
small bugs I don't even remember now.

This patch has been tested on all supported in 2.6 PPC 4xx boards.
It's been used in production for almost a year now on custom
4xx hardware. PPC32 specific parts are already upstream.

Patch was acked by the current EMAC driver maintainer (Matt Porter). I
will be maintaining this new version.

This patch fixes a bug that happens when the hypervisor can't add a

called BUG().  The patch writes the right value into the free_map array

This patch removes the allocation of RX skb's  buffers from a workqueue
to be called directly at RX processing time.  This change was suggested
by Dave Miller when the driver was starving the RX buffers and
deadlocking under heavy traffic:

> Allocating RX SKBs via tasklet is, IMHO, the worst way to
> do it.  It is no surprise that there are starvation cases.
>
> If tasklets or work queues get delayed in any way, you lose,
> and it's very easy for a card to catch up with the driver RX'ing
> packets very fast, no matter how aggressive you make the
> replenishing.  By the time you detect that you need to be
> "more aggressive" it is already too late.

This patch changes the way the ibmveth driver handles the receive

regardless of MTU size and it also limits the number of buffer pools to
three. This patch makes the driver malloc and map the buffers necessary
to support the current MTU. It also changes the hardcoded names of the
buffer pool number, size, and elements to arrays to make it easier to
change (with the hope of making them runtime parameters in the future).

Russell King 9480e307cd [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks
In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

Ben Dooks a1bdc7aad8 [PATCH] drivers/base - fix sparse warnings
There are a number of sparse warnings from the latest sparse
snapshot being generated from the drivers/base build. The
main culprits are due to the initialisation functions not
being declared in a header file.

Also, the firmware.c file should include <linux/device.h>
to get the prototype of  firmware_register() and
firmware_unregister().

This patch moves the init function declerations from the
init.c file to the base.h, and ensures it is included in
all the relevant c sources. It also adds <linux/device.h>
to the included headers for firmware.c.

The patch does not solve all the sparse errors generated,
but reduces the count significantly.

This patch allows struct class_device to be nested, so that another
struct class_device can be the parent of a new one, instead of only
having the struct class be the parent.  This will allow us to
(hopefully) fix up the input and video class subsystem mess.

But please people, don't go crazy and start making huge trees of class
devices, you should only need 2 levels deep to get everything to work
(remember to use a class_interface to get notification of a new class
device being added to the system.)

Oh, this also allows us to have the possibility of potentially, someday,
moving /sys/block into /sys/class.  The main hindrance is that pesky
/dev numberspace issue...

This patch teaches "usb_device" about the new driver model wakeup support:

 - It updates device wakeup capabilities when entering a configuration
   with the WAKEUP attribute;

 - During suspend processing it consults the policy bit to see
   whether it should enable wakeup for that device.  (This resolves
   a FIXME to not assume the answer is always "yes"; some devices
   lie about supporting remote wakeup.)

Support for root hubs and the HCDs is separate (and more complex).

This is a refresh of an earlier patch to add "wakeup" support to the
PM core model.  This provides per-device bus-neutral control of the
use of wakeup events.

  * "struct device_pm_info" has two bits that are initialized as
    part of setting up the enclosing struct device:
      - "can_wakeup", reflecting hardware capabilities
      - "may_wakeup", the policy setting (when CONFIG_PM)

  * There's a writeable sysfs "wakeup" file, with one of two values:
      - "enabled", when the policy is to allow wakeup
      - "disabled", when the policy is not to allow it
      - "" if the device can't currently issue wakeups

By default, wakeup is enabled on all devices that support it.  If its
driver doesn't support it ... treat it as a bug.  :)

expires; or 2) a SCSI command completes with an error.

As long as the host software (qla2xxx) services the response
queue for completions (this polling is done during
queuecommand()) within the 'delay timer' period, the
firmware will not generate system interrupt.

Ian Campbell 63a4b52c9d [ARM] 3044/1: Fix sparse warnings about incompatible pointer types for register defined in pxa-regs.h
Patch from Ian Campbell

The sparse warning initially surfaced in sound/arm/pxa2xx-ac97.c
because it was using u32 * variables to hold the unsigned long *
register addresses.

I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register
definitions to use u32.

Most other subarches seem to use u32 for their register type, at least
the ones which use a __REG macro (like the PXA) do. Nico indicated in
the thread above that he wouldn't mind this patch.

Changing the type required fixes for opposite warnings in the pxa2xx usb
gadget code but that was the only new warning introduced on defconfig
or lubbock, mainstone and our own PXA255 boards.

Tejun Heo cb98fc8bb9 [BLOCK] Reimplement elevator switch
This patch reimplements elevator switch.  This patch assumes generic
dispatch queue patchset is applied.

 * Each request is tagged with REQ_ELVPRIV flag if it has its elevator
   private data set.
 * Requests which doesn't have REQ_ELVPRIV flag set never enter
   iosched.  They are always directly back inserted to dispatch queue.
   Of course, elevator_put_req_fn is called only for requests which
   have its REQ_ELVPRIV set.
 * Request queue maintains the current number of requests which have
   its elevator data set (elevator_set_req_fn called) in
   q->rq->elvpriv.
 * If a request queue has QUEUE_FLAG_BYPASS set, elevator private data
   is not allocated for new requests.

 To switch to another iosched, we set QUEUE_FLAG_BYPASS and wait until
elvpriv goes to zero; then, we attach the new iosched and clears
QUEUE_FLAG_BYPASS.  New implementation is much simpler and main code
paths are less cluttered, IMHO.

Jens Axboe b4878f245e [PATCH] 02/05: update ioscheds to use generic dispatch queue
This patch updates all four ioscheds to use generic dispatch
queue.  There's one behavior change in as-iosched.

* In as-iosched, when force dispatching
  (ELEVATOR_INSERT_BACK), batch_data_dir is reset to REQ_SYNC
  and changed_batch and new_batch are cleared to zero.  This
  prevernts AS from doing incorrect update_write_batch after
  the forced dispatched requests are finished.

* In cfq-iosched, cfqd->rq_in_driver currently counts the
  number of activated (removed) requests to determine
  whether queue-kicking is needed and cfq_max_depth has been
  reached.  With generic dispatch queue, I think counting
  the number of dispatched requests would be more appropriate.

* cfq_max_depth can be lowered to 1 again.

Roland Dreier 3d155f8cd0 [IB] mthca: first pass at catastrophic error reporting
Add some initial support for detecting and reporting catastrophic
errors reported by Mellanox HCAs.  We start a periodic timer which
polls the catastrophic error reporting buffer in device memory.  If an
error is detected, we dump the contents of the buffer for port-mortem
debugging, and report a fatal asynchronous error to higher levels.

In the future we can try to recover from these errors by resetting the
device, but this will require some work in higher-level code as well.
Let's get this in now, so that we at least get catastrophic errors
reported in logs.

Andrew Morton 444d1d9bb5 [PATCH] qlogic lockup fix
If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call
qla2x00_free_device() to clean up.  But because ha->dpc_pid hasn't been set
yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started
yet.  It does wait_for_completion() against an uninitialised completion struct
and the kernel hangs up.

Fix it by initialising ha->dpc_pid a bit earlier.

Roland Dreier 547e309073 [IB] mthca: correct modify QP attribute masks for UC
The UC transport does not support RDMA reads or atomic operations, so
we shouldn't require or even allow the consumer to set attributes
relating to these operations for UC QPs.

Sean Hefty 34816ad98e [IB] Fix MAD layer DMA mappings to avoid touching data buffer once mapped
The MAD layer was violating the DMA API by touching data buffers used
for sends after the DMA mapping was done.  This causes problems on
non-cache-coherent architectures, because the device doing DMA won't
see updates to the payload buffers that exist only in the CPU cache.

Fix this by having all MAD consumers use ib_create_send_mad() to
allocate their send buffers, and moving the DMA mapping into the MAD
layer so it can be done just before calling send (and after any
modifications of the send buffer by the MAD layer).

Tested on a non-cache-coherent PowerPC 440SPe system.

On 2005-05-01, Gerd Knorr sent in a patch to add cx22702 to cx88-dvb:

 [PATCH] dvb: cx22702 frontend driver update
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9990d744bea7d28e83c420e2c9d524c7a8a2d136

...but as we can see, the Kconfig portion of his patch was incorrectly
applied to saa7134-dvb instead of cx88-dvb.

On 2005-06-24, Adrian bunk fixed cx88-dvb:

 [PATCH] VIDEO_CX88_DVB must select DVB_CX22702
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d6988588e13616587aa879c2e0bd7cd811705e5d

...but we never removed the original patch from Gerd.

This patch sets things straight:

That's what we've always historically done, and bigger windows seem to
confuse some cardbus bridges. Or something.

Alan reports that this makes the ThinkPad 600x series work properly
again: the 4kB IO window for some reason made IDE DMA not work, which
makes IDE painfully slow even if it works after DMA timeouts.
