When processes are allowed to attempt to lock a non-contiguous range of nfs
write requests, it is possible for generic_writepages to 'wrap round' the
address space, and call writepage() on a request that is already locked by
the same process.

We avoid the deadlock by checking if the page index is contiguous with the
list of nfs write requests that is already held in our
nfs_pageio_descriptor prior to attempting to lock a new request.

It turns out from customer reports to Red Hat and some PCI dumps that the
MegaIDE in RAID mode doesn't provide the drive tuning data that the
serverworks driver expects but sometimes does provide something that
fools the code.

For the RAID class case skip the oem setup and don't trust the BIOS data.
We then tune from scratch and this sorts it out. (This has been confirmed
on an afflicted IBM blade)

[libata serverworks.c never trusts the BIOS in the first place so is
accidentally immune]

This patch (as905) removes a micro-optimization from the hub port
initialization code.  Previously we had been using a short timeout on
the first attempt the read the device descriptor; now we will use the
standard timeout length.

It's not clear that the short timeout ever provided any benefit.  And
now we know of one case where it actually hurts: The device can't meet
the short timeout and then it gets terminally confused.

This patch (as883) removes an out-of-date WARN_ON from the main HCD
endpoint-disable routine.  The warning is triggered whenever an
endpoint is disabled while the root hub is suspended.  In the past
that may not have been legal, but it definitely is legal now.  Merely
unbinding a USB driver will do it.

Furthermore, I've never seen any occurrences of this warning that
really did signal an actual bug or error condition.  At this point it
has outlived its purpose.

These are things I didn't think to include at the time but which

	If an autosuspend fails because driver activity races with
	the autosuspend call, restart the autosuspend timer.

	When a device is resumed by an external request, it counts
	as device activity and should update the last_busy time so
	that the next autoresume won't occur immediately.

This patch (as882) fixes a problem with the EHCI BIOS handoff.  On my
machine, the BIOS configures the controller and the handoff fails,
leaving the controller configured.  During resume-from-disk, this
confuses ehci-hcd into thinking that the controller has not been
tampered with.

The problem is fixed by turning off the Configured Flag whenever a
BIOS handoff is attempted, whether it succeeds or not.

In commit [1] the SPI mode is set to 1, but it should be 0.  As stated
in the commit, ads784x samples the data on the rising edge.  SPI mode 1
samples on the falling edge [2] though.

The root cause of this is a bug in the omap_uwire code, which treats
CPHA=1 incorrectly; so these two bugs cancel each other out on one
of the main regression test platforms for this driver.
