sata_nv: don't read shadow registers when in ADMA mode
Reading from the ATA shadow registers while we are in ADMA mode may cause

notify us if the command failed. Also, don't allow commands with result

SATA version

SATA version, that both call a common version after
setting up the `hardreset' function pointer
* pdc_old_check_atapi_dma() is now only used for SATAI
ports, so is renamed to pdc_old_sata_check_atapi_dma()

* pdc_sata_scr_{read,write}() are now only used for SATA
ports, so their is-not-SATA tests are removed
* pdc_port_start() is split into three procedures: a wrapper
which performs the ->ops adjustment on TX2plus PATA ports,
a procedure with the common code, and a procedure with

libata/IDE: remove combined mode quirk
Both old-IDE and libata should be able handle all controllers and
devices found using normal resource reservation methods.
This eliminates the awful, low-performing split-driver configuration
where old-IDE drove the PATA portion of a PCI device, in PIO-only mode,
and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
Typically vendors would ship SATA hard drive / PATA optical
configuration, which would lend itself to slow (PIO-only) CD-ROM
performance.
For Intel users running in combined mode, it is now wholly dependent on
your driver choice (potentially link order, if you compile both drivers
in) whether old-IDE or libata will drive your hardware.
In either case, you will get full performance from both SATA and PATA
ports now, without having to pass a kernel command line parameter.

libata: cable detection fixes
2.6.21-rc has horrible problems with libata and PATA cable types (and
thus speeds). This occurs because Tejun fixed a pile of other bugs and
we now do cable detect enforcement for drive side detection properly.
Unfortunately we don't do the process around cable detection right. Tejun
identified the problem and pointed to the right Annex in the spec, this patch
implements the rest of the needed changes.
We add a ->cable_detect() method called after the identify
sequence which allows a host to do host side detection at this point
should it wish, or to modify the results of the drive side identify.
This separate ->cable_detect method also cleans up a lot of code because
many drivers have their own error_handler methods which really just set
the cable type.
If there is no ->cable_detect method the cable type is left alone so a
driver setting it earlier (eg because it has the SATA flags set or
because it uses the old error_handler approach) will still do the right
thing (or at least the same thing) as before.
This patch simply adds the cable_detect method and helpers it doesn't use
them but other follow up patches will (ie Adrian please don't submit
patches to unexport them ;))

sis900: Allocate rx replacement buffer before rx operation
Just found a hole in my last patch. It was reported to me that shortly after we
integrated this patch. The report was of an oops that took place inside of
netif_rx when using the sis900 driver. Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame. The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring. So if you receive frames fast enough the skb being processed by
the network stack can get corrupted. The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP. I'll post test results when I hear
them, but I think this is a pretty straightforward fix. It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.

Use the new ohci-pci quirk infrastructure to address the problem it was
created to address: a quirk specific to the Portege 4000, in buzilla as
http://bugzilla.kernel.org/show_bug.cgi?id=6723
Also fix a misuse of "__devinit" for the quirk functions. It must not
be used without first ensuring that the references from the quirk tables
are gone, and that the function using those quirk tables is also gone.

USB: usbnet reports minidriver name through ethtool
Update "usbnet" so that ethtool reports the name of the minidriver in use
(e.g. asix, cdc_ether, dm9601, rndis_host) instead of "usbnet". This is a
better match to how other network drivers work, resolving a minor open issue.

USB: rndis_host, various cleanups
Cleanups to the rndis_host code, and a tweak that helps talking to
PXA hardware. Mostly from Ole André Vadla Ravnås <oleavr@gmail.com>
- Prevent SET_INTERFACE requests, they give PXA hardware bad indigestion
- For paranoia, null a pointer after freeing its data
- Wrap up ActiveSync oddities for RNDIS_QUERY in one routine
- Use that wrapper when getting the Ethernet address
- Whitespace fixes
Plus add a comment noting the open issues about some RNDIS clients still
needing TBD kinds of browbeating to accept non-jumbogram packets.

usbmon: bus zero
Add the "bus zero" feature to the usbmon. If a user process specifies bus
with number zero, it receives events from all buses. This is useful when
we wish to see initial enumeration when a bus is created, typically after
a modprobe. Until now, an application had to loop until a new bus could
be open, then start capturing on it. This procedure was cumbersome and
could lose initial events. Also, often it's too bothersome to find exactly
to which bus a specific device is attached.
Paolo Albeni provided the original concept implementation. I added the
handling of "bus->monitored" flag and generally fixed it up.

USB: Allow transfer_buffer with transfer_dma
Some host controller drivers may need a PIO fallback when a DMA channel
is temporarily unavailable. This patch provides an address that such
drivers can use for PIO in those cases, and nulls that field out when
no such address is available (highmem) which should help usbmon.

USB: add "last_busy" field for use in autosuspend
This patch (as877) adds a "last_busy" field to struct usb_device, for
use by the autosuspend framework. Now if an autosuspend call comes at
a time when the device isn't busy but hasn't yet been idle for long
enough, the timer can be set to exactly the desired value. And we
will be ready to handle things like HID drivers, which can't maintain
a useful usage count and must rely on the time-of-last-use to decide
when to autosuspend.
The patch also makes some related minor improvements:
Move the calls to the autosuspend condition-checking routine
into usb_suspend_both(), which is the only place where it
really matters.
If the autosuspend timer is already running, don't stop
and restart it.
Replace immediate returns with gotos so that the optional
debugging ouput won't be bypassed.
If autoresume is disabled but the device is already awake,
don't return an error for an autoresume call.
Don't try to autoresume a device if it isn't suspended.
(Yes, this undercuts the previous change -- so sue me.)
Don't duplicate existing code in the autosuspend work routine.
Fix the kerneldoc in usb_autopm_put_interface(): If an
autoresume call fails, the usage counter is left unchanged.

USB: fix omninet write vs. close race
omninet kills all URBs in close. However write() returns as soon as
the URB has been submitted. Killing the last URB means a race that
can lose that date written in the last call to write().
As a fix this is moved to shutdown().
