Some USB device controllers make it easy to handle all the various ways
hosts interpret the USB spec about when control-IN transfers need to send
a ZLP ... they can just send one if the host asks, or start the status
stage whenever the host thinks it's time.  Other controllers make it hard
to be forgiving in those cases.

This patch updates all the gadget drivers to explicitly set the req->zero
flag to reflect whether the USB spec says a ZLP "must" be sent by the
device.  "Forgiving" drivers won't notice the change, but the others need
to see this information passed down from the gadget driver.

In a recent thread it was mentioned that some architectures, such as PPC,
do not guarantee relative ordering between different varieties of
processor/device data transfers.  This patch adds an mb() instruction to
the UHCI driver, to insure that the data structures in memory (cached by
the CPU and accessed by DMA) are fully flushed before the controller is
started (by regular bus IO).

A tricky problem the dummy_hcd driver has to solve is keeping track of the
usb_device structure that corresponds to a registered gadget.  Right now
that's not done very robustly.  This patch stores the address of the
structure when a new URB is submitted and also acquires a reference to
make sure that completing the final URB won't deallocate the structure
before dummy_hcd is through with it.

Thanks to Ludovic Aubry for this patch.  It changes some local variables
used by the UHCI driver to store IO addresses from unsigned int to
unsigned long.  This is vitally necessary on 64-bit platforms.

Various tweaks to EHCI IRQ handling, these may affact some systems.

 - Delays enabling IRQs until the root hub is more fully set up, so
   any "resume detect" IRQs can be handled properly.  (Craig Nadler)

 - Power down ports on driver shutdown.  (Craig Nadler)

 - Remove some duplicate irq-sharing logic that somehow crept in; check
   only once, and return IRQ_NONE to detect IRQ storms better (db)

 - Minor comment fix re integrated TTs.  (db)

This patch fixes another bug in the dummy_hcd driver.  When a gadget
driver unregisters (simulating a device disconnect), dummy_hcd stops the
timer that it uses for processing outstanding URBs.  Unfortunately this
means that those URBs will never be given back.  The patch lets the timer
continue running; when it expires all the remaining URBs will fail so the
timer won't be reinitialized.

This patch implements the missing functionality necessary to get device
resets working fully.  It adds a bit-array of ports with logical
connect-changes pending to the hub structure, so that the hub driver can
recognize that these ports should be treated as though they had
disconnected and re-connected.  This is how we will handle devices that
"morph" (i.e., change their descriptors) following a reset, as might
happen with a firmware upload.

There is also a lot of additional kerneldoc and a few small changes to
some log messages.  An important restriction is that usb_reset_device()
will refuse to work if the device is suspended.  Trying to reset a
suspended device leads to several problems, not least of which is that the
device's parent hub might be suspended as well.

With this patch the device reset code is pretty much complete.  However it
won't always work correctly until the device locking is straightened out.
That's coming up next.

Also clean it all up - use get_cpu()/put_cpu() instead of
playing games by hand with preemption.

Here is a simple patch which drops some out-of-date code in the w83781d
and w83627hf i2c chip drivers. These bits are left over from the times
when chip drivers were setting default limits at init.

Split ata_eng_timeout into the main part (ata_qc_timeout)
and the part called by the SCSI layer (ata_eng_timeout).

Zero behavior changes.

by "other". The normal permissions for the kernel tree
should be -rw-r--r--.

sock_fprog instances that had kernel pointer in ->filter (both of them -
in ppp_generic and isdn_ppp) replaced with explicit pairs len + kernel
pointer.  Copying of userland sock_fprog (with its __user ->filter)
cleaned up and sanitized.

Trivial annotation done in the rest of ->ioctl() in ppp_generic and
isdn_ppp.
