Commit 330605423c fixed l2cap conn establishment for non-ssp remote
devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security
is tested (which was always returning failure on any subsequent
security checks).
However, this broke l2cap conn establishment for ssp remote devices
when an ACL link was already established at SDP-level security. This
fix ensures that encryption must be pending whenever authentication
is also pending.

It turns out that many compilers don't show section warnings on ARM
currently because handling for ARM_CALL relocs are missing from
modpost.c.
Based on commit c2e26114 ([ARM] 3205/1: Handle new EABI relocations when
loading kernel modules) it seems that R_ARM_PC24, R_ARM_CALL and
R_ARM_JUMP24 can be handled the same way.
Note that at least Debian libc6-dev is missing defines for both
R_ARM_CALL and R_ARM_JUMP24 in /usr/include/elf.h. So for now
we need to define them in modpost.c if not defined.

An interrupt might be pending when irq_startup() is called, but the
startup code does not invoke the resend logic. In some cases this
prevents the device from issuing another interrupt which renders the
device non functional.
Call the resend function in irq_startup() to keep things going.

When the primary handler of an interrupt which is marked IRQ_ONESHOT
returns IRQ_HANDLED or IRQ_NONE, then the interrupt thread is not
woken and the unmask logic of the interrupt line is never
invoked. This keeps the interrupt masked forever.
This was not noticed as most IRQ_ONESHOT users wake the thread
unconditionally (usually because they cannot access the underlying
device from hard interrupt context). Though this behaviour was nowhere
documented and not necessarily intentional. Some drivers can avoid the
thread wakeup in certain cases and run into the situation where the
interrupt line s kept masked.
Handle it gracefully.

This is a flexible USB Audio Class 2.0 compliant gadget driver that
implements a simple topology with a virtual sound card exposed at
the function side.
The driver doesn't expect any real audio codec to be present on the
function - the audio streams are simply sinked to and sourced from a
virtual ALSA sound card created. The user-space application may choose
to do whatever it wants with the data received from the USB Host and
choose to provide whatever it wants as audio data to the USB Host.
Capture(USB-Out) and Playback(USB-In) can be run at independent
configurations specified via module parameters while loading the driver.
Make this new version as the default selection by a new Kconfig choice.

This hooks dtc into Kbuild's dependency system.
Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous
lack of this feature recently caused me to have very confusing "git
bisect" results.
For ARM, it's obvious what to add to $(targets). I'm not familiar enough
with other architectures to know what to add there. Powerpc appears to
already add various .dtb files into $(targets), but the other archs may
need something added to $(targets) to work.

Support for USB 3.0 hub suspend.
This patchset adds support for suspending external USB 3.0 hubs, and fixes the
USB 3.0 device remote wakeup enabling. Hubs are the only USB 3.0 devices on
the market right now that do remote wakeup, and they will only send a remote
wakeup if they are placed into suspend, so it's not necessary to backport this
patchset to stable kernels.

Now that USB 3.0 hub remote wakeup on port status changes is enabled,

This patch takes care of the race condition between the Function Wake
Device Notification and the auto-suspend timeout for this situation:
Roothub
| (U3)
hub A
| (U3)
hub B
| (U3)
device C
When device C signals a resume, the xHCI driver will set the wakeup_bits
for the roothub port that hub A is attached to. However, since USB 3.0
hubs do not set a link state change bit on device-initiated resume, hub
A will not indicate a port event when polled. Without this patch, khubd
will notice the wakeup-bits are set for the roothub port, it will resume
hub A, and then it will poll the events bits for hub A and notice that
nothing has changed. Then it will be suspended after 2 seconds.
Change hub_activate() to look at the port link state for each USB 3.0
hub port, and set hub->change_bits if the link state is U0, indicating
the device has finished resume. Change the resume function called by
hub_events(), hub_handle_remote_wakeup(), to check the link status
for resume instead of just the port's wakeup_bits.

USB 3.0 hubs don't have a port suspend change bit (that bit is now
reserved). Instead, when a host-initiated resume finishes, the hub sets
the port link state change bit.
When a USB 3.0 device initiates remote wakeup, the parent hubs with
their upstream links in U3 will pass the LFPS up the chain. The first
hub that has an upstream link in U0 (which may be the roothub) will
reflect that LFPS back down the path to the device.
However, the parent hubs in the resumed path will not set their link
state change bit. Instead, the device that initiated the resume has to
send an asynchronous "Function Wake" Device Notification up to the host
controller. Therefore, we need a way to notify the USB core of a device
resume without going through the normal hub URB completion method.
First, make the xHCI roothub act like an external USB 3.0 hub and not
pass up the port link state change bit when a device-initiated resume
finishes. Introduce a new xHCI bit field, port_remote_wakeup, so that
we can tell the difference between a port coming out of the U3Exit state
(host-initiated resume) and the RExit state (ending state of
device-initiated resume).
Since the USB core can't tell whether a port on a hub has resumed by
looking at the Hub Status buffer, we need to introduce a bitfield,
wakeup_bits, that indicates which ports have resumed. When the xHCI
driver notices a port finishing a device-initiated resume, we call into
a new USB core function, usb_wakeup_notification(), that will set
the right bit in wakeup_bits, and kick khubd for that hub.
We also call usb_wakeup_notification() when the Function Wake Device
Notification is received by the xHCI driver. This covers the case where
the link between the roothub and the first-tier hub is in U0, and the
hub reflects the resume signaling back to the device without giving any
indication it has done so until the device sends the Function Wake
notification.
Change the code in khubd that handles the remote wakeup to look at the
state the USB core thinks the device is in, and handle the remote wakeup
if the port's wakeup bit is set.
This patch only takes care of the case where the device is attached
directly to the roothub, or the USB 3.0 hub that is attached to the root
hub is the device sending the Function Wake Device Notification (e.g.
because a new USB device was attached). The other cases will be covered
in a second patch.

USB 3.0 hubs have a different remote wakeup policy than USB 2.0 hubs.
USB 2.0 hubs, once they have remote wakeup enabled, will always send
remote wakes when anything changes on a port.
However, USB 3.0 hubs have a per-port remote wake up policy that is off
by default. The Set Feature remote wake mask can be changed for any
port, enabling remote wakeup for a connect, disconnect, or overcurrent
event, much like EHCI and xHCI host controller "wake on" port status
bits. The bits are cleared to zero on the initial hub power on, or
after the hub has been reset.
Without this patch, when a USB 3.0 hub gets suspended, it will not send
a remote wakeup on device connect or disconnect. This would show up to
the user as "dead ports" unless they ran lsusb -v (since newer versions
of lsusb use the sysfs files, rather than sending control transfers).
Change the hub driver's suspend method to enable remote wake up for
disconnect, connect, and overcurrent for all ports on the hub. Modify
the xHCI driver's roothub code to handle that request, and set the "wake
on" bits in the port status registers accordingly.

The USB 3.0 bus specification introduces a new type of power management
called function suspend. The idea is to be able to suspend different
functions (i.e. a scanner or an SD card reader on a USB printer)
independently. A device can be in U0, but have one or more functions
suspended. Thus, signaling a function resume with the standard device
remote wake signaling was not possible.
Instead, a device will (without prompt from the host) send a "device
notification" for the function remote wake. A new Set Feature Function
Remote Wake was developed to turn remote wake up on and off for each
function.
USB 3.0 devices can still go into device suspend (U3), and signal a
remote wakeup to bring the link back into U1. However, they now use the
function remote wake device notification to allow the host to know which
function woke the device from U3.
The spec is a bit ambiguous about whether a function is allowed to
signal a remote wakeup if the function has been enabled for remote
wakeup, but not placed in function suspend before the device is placed
into U3.
Section 9.2.5.1 says "Suspending a device with more than one function
effectively suspends all the functions within the device." I interpret
that to mean that putting a device in U3 suspends all functions, and
thus if the host has previously enabled remote wake for those functions,
it should be able to signal a remote wake up on port status changes.
However, hub vendors may have a different interpretation, and it can't
hurt to put the function into suspend before putting the device into U3.
I cannot get an answer out of the USB 3.0 spec architects about this
ambiguity, so I'm erring on the safe side and always suspending the
first function before placing the device in U3. Note, this code should
be fixed if we ever find any USB 3.0 devices that have more than one
function.

When the USB 3.0 hub support went in, I disabled selective suspend for
all external USB 3.0 hubs because they used a different mechanism to
enable remote wakeup. In fact, other USB 3.0 devices that could signal
remote wakeup would have been prevented from going into suspend because
they would have stalled the SetFeature Device Remote Wakeup request.
This patch adds support for the USB 3.0 way of enabling remote wake up
(with a SetFeature Function Suspend request), and enables selective
suspend for all hubs during hub_probe. It assumes that all USB 3.0 have
only one "function" as defined by the interface association descriptor,
which is true of all the USB 3.0 devices I've seen so far. FIXME if
that turns out to change later.
After a device signals a remote wakeup, it is supposed to send a Device
Notification packet to the host controller, signaling which function
sent the remote wakeup. The host can then put any other functions back
into function suspend. Since we don't have support for function suspend
(and no devices currently support it), we'll just assume the hub
function will resume the device properly when it received the port
status change notification, and simply ignore any device notification
events from the xHCI host controller.

xHCI roothubs go through slightly different port state machines when
either a device initiates a remote wakeup and signals resume, or when
the host initiates a resume.
According to section 4.19.1.2.13 of the xHCI 1.0 spec, on host-initiated
resume, the xHC port state machine automatically goes through the U3Exit
state into the U0 state, setting the port link state change (PLC) bit in
the process.
When a device initiates resume, the xHCI port state machine goes into
the "Resume" state and sets the PLC bit. Then the xHCI driver writes U0
into the port link state register to transition the port to U0 from the
Resume state.
We can't be sure the device is actually in the U0 state until we receive
the next port status change event with the PLC bit set. We really don't
want khubd to be polling the roothub port status bits until the device
is really in U0.

This commit ensures that lost_cnt_hint is correctly updated in

need their own adjustment.
This applies the spirit of 1e5289e121372a3494402b1b131b41bfe1cf9b7f -
except now that the sequence range passed into tcp_sacktag_one() is

Intel has a PCI USB xhci host controller on a new platform. It doesn't
have a line IRQ definition in BIOS. The Linux driver refuses to

Actually, Linux also can work for MSI. This patch avoids the line IRQ
checking for USB3 HCDs in usb core PCI probe. It allows the xHCI driver
to try to enable MSI or MSI-X first. It will fail the probe if MSI
enabling failed and there's no legacy PCI IRQ.
This patch should be backported to kernels as old as 2.6.32.

an atomic (tasklet) context, which is not supported by the shdma dmaengine
driver. Fix it by switching to a work.
