The upcoming Intel Lynx Point chipset includes an xHCI host controller
that can have ports switched from the EHCI host controller, just like
the Intel Panther Point xHCI host. This time, ports from both EHCI
hosts can be switched to the xHCI host controller. The PCI config
registers to do the port switching are in the exact same place in the
xHCI PCI configuration registers, with the same semantics.
Hooray for shipping patches for next-gen hardware before the current gen
hardware is even available for purchase!

If the user chooses to say "no" to CONFIG_USB_XHCI_HCD on a system
with an Intel Panther Point chipset, the PCI quirks code or the EHCI
driver will switch the ports over to the xHCI host, but the xHCI driver
will never load. The ports will be powered off and seem "dead" to the
user.
Fix this by only switching the ports over if CONFIG_USB_XHCI_HCD is
either compiled in, or compiled as a module.

While testing unplugging an UVC HD webcam with usb-redirection (so through
usbdevfs), my userspace usb-redir code was getting a value of -1 in
iso_frame_desc[n].status, which according to Documentation/usb/error-codes.txt
is not a valid value.
The source of this -1 is the default case in xhci-ring.c:process_isoc_td()
adding a kprintf there showed the value of trb_comp_code to be COMP_TX_ERR
in this case, so this patch adds handling for that completion code to
process_isoc_td().
This was observed and tested with the following xhci controller:
1033:0194 NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04)
Note: I also wonder if setting frame->status to -1 (-EPERM) is the best we can
do, but since I cannot come up with anything better I've left that as is.
This patch should be backported to kernels as old as 2.6.36, which contain the
commit 04e51901dd44f40a5a385ced897f6bca87d5f40a "USB: xHCI: Isochronous
transfer implementation".

This commit adds a bit-array to xhci bus_state for keeping track of
which ports are undergoing a resume transition. If any of the bits
are set when xhci_hub_status_data() is called, the routine will return
a non-zero value even if no ports have any status changes pending.
This will allow usbcore to handle races between root-hub suspend and
port wakeup.
This patch should be backported to kernels as old as 3.4, that contain
the commit 879d38e6bc36d73b0ac40ec9b0d839fda9fa8b1a "USB: fix race
between root-hub suspend and remote wakeup".

Commit af4e1ee04026908086d7ed252db2619a8ceaa333 (usb-next)
"USB: remove err() macro"
was preceeded by a tree-wide cleanup of users, however this
one squeaked through the cracks because it had whitespace
between the function name and the bracket for the args.
Map it onto dev_err, just like all the "pre-commits" made
in advance of af4e1ee04026, such as the example seen in
the commit d57b177208b6ec20cacd7321ee32ef02f9f9e7fa:
"USB: ohci-xls.c: remove err() usage"

In the SetPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control()
would read from status_reg, modify the value, and write the result back to
status_reg. This would clear any bits in PORT_RWC_BITS that were set in
the register. Fix this by masking these bits off before the write.
This is logically the same change as 6d5f89c "USB: EHCI: remove
PORT_RWC_BITS when clearing USB_PORT_FEAT_ENABLE", but applied to the
Tegra driver rather than the USB core.

The ehci-hcd driver is a little haphazard about keeping track of the
state of the USBCMD register. The ehci->command field is supposed to
hold the register's value (apart from a few special bits) at all
times, but it isn't maintained properly.
This patch (as1543) cleans up the situation. It keeps ehci->command
up-to-date, and uses that value rather than reading the register from
the hardware whenever possible.

err() was a very old USB-specific macro that I thought had
gone away. This patch removes it from being used in the
driver and uses dev_err() instead.

In the ClearPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control()
would read from status_reg, clear PORT_PE, and write the result back to
status_reg. This would clear any bits in PORT_RWC_BITS that were set in
the registers. Fix this by masking these bits off before the write.
Since this masking is common across all ClearPortFeature cases, move it
into a single early location to avoid duplicating it.
Remove the same bugfix from ehci-tegra.c's tegra_ehci_hub_control(), now
that this case is correctly handled by the core.

This patch (as1541) corrects a small mistake in ehci-hcd. The IAAD
(Interrupt on Async Advance Doorbell) bit in the USBCMD register is
designed, as its name says, to act as a "doorbell". That is, the
driver activates the bit by setting it to 1, and the hardware
deactivates it later by setting it back to 0. The driver cannot clear
the bit by writing a 0 to it; such writes are simply ignored.
Therefore there is no reason for ehci-hcd to try to clear the bit.
The patch removes the two instances where such attempts occur.

Make sure that dequeued urbs get handled first
by collect_qtds. To achieve that we better move them

This for instance fixes hanging serial devices, which wait
