9f6a93f7bb usb: free DMA mappings if enqueue fails
This patch releases DMA resources if enqueue fails in the HCD.

Linux had this bug ever since we converted from virt_to_bus for 2.4.
It is difficult to hit. A user would need a significant memory pressure
or some other unusual condition.

It was reported to me by IBM. They ran a management application for
RSA II adapters which sent Bulk requests to an Interrupt endpoint.
Submissions got rejected by HCD due to an invalid interval value
and the swiotlb pool became depleted in the matter of hours.

We fixed the invalid interval issue in devio.c separately, but this
seems to be a bug worth fixing as well.

52f6b5e1f1 synchronization in usb_serial_put
I think there is a race between usb_serial_put() and
usb_serial_get_by_index() (and get_free_serial()) with regards
to handling the serial port refcount.

usb_serial_get_by_index() gets a reference on the serial port under
table_lock while return_serial releases all the returned ports
from the table under the same lock.  However, the table_lock is not
taken around the call to kref_put, theoretically allowing to sneak
in and grab a reference after kref_put has already determined that
the reference count is zero (and before calling destroy_serial)
causing use after free.

756aa6b3d5 ehci-hub: improved over-current recovery
According to the USB Specification Revision 2.0 chapter 11.12.5
a hub experiencing an over-current condition must place all
affected ports in the powered-off state. It seems that some root
hubs need port power to be cycled by software in order to get back
to normal functionality after an over-current condition ... like
the EHCI implementation on an MPC8343E.

ed76cacbea USB: usb-storage: use kthread_stop() for the control thread
This patch (as923) makes usb-storage's control thread use
kthread_should_stop()/kthread_stop().  The scanning thread can't be
similarly converted until the core kthread implementation allows
threads to call do_exit().

The advantage of this change is that we can now be certain the control
thread has terminated before storage_disconnect() returns.  This will
simplify the locking requirements when autosuspend support is added.

Okay, from this it looks like there's a problem in the option.c serial
driver.  Glancing at the code, it's obvious why: The thing totally
abuses the USB API.

Try applying this patch; it should help.

b41a60eca8 USB: add power/persist device attribute
This patch (as920) adds an extra level of protection to the
USB-Persist facility.  Now it will apply by default only to hubs; for
all other devices the user must enable it explicitly by setting the
power/persist device attribute.

The disconnect_all_children() routine in hub.c has been removed and
its code placed inline.  This is the way it was originally as part of
hub_pre_reset(); the revised usage in hub_reset_resume() is
sufficiently different that the code can no longer be shared.
Likewise, mark_children_for_reset() is now inline as part of
hub_reset_resume().  The end result looks much cleaner than before.

The sysfs interface is updated to add the new attribute file, and
there are corresponding documentation updates.

54515fe528 USB: unify reset_resume and normal resume
This patch (as919) unifies the code paths used for normal resume and
for reset-resume.  Earlier I had failed to note a section in the USB
spec which requires the host to resume a suspended port before
resetting it if the attached device is enabled for remote wakeup.
Since the port has to be resumed anyway, we might as well reuse the
existing code.

The main changes are:

	usb_reset_suspended_device() is eliminated.

	usb_root_hub_lost_power() is moved down next to the
	hub_reset_resume() routine, to which it is logically
	related.

	finish_port_resume() does a port reset() if the device's
	reset_resume flag is set.

	usb_port_resume() doesn't check whether the port is initially
	enabled if this is a USB-Persist sort of resume.

	Code to perform the port reset is added to the resume pathway
	for the non-CONFIG_USB_SUSPEND case.

f07600cf9e USB: add reset_resume method
This patch (as918) introduces a new USB driver method: reset_resume.
It is called when a device needs to be reset as part of a resume
procedure (whether because of a device quirk or because of the
USB-Persist facility), thereby taking over a role formerly assigned to
the post_reset method.  As a consequence, post_reset no longer needs
an argument indicating whether it is being called as part of a
reset-resume.  This separation of functions makes the code clearer.

In addition, the pre_reset and post_reset method return types are
changed; they now must return an error code.  The return value is
unused at present, but at some later time we may unbind drivers and
re-probe if they encounter an error during reset handling.

The existing pre_reset and post_reset methods in the usbhid,
usb-storage, and hub drivers are updated to match the new
requirements.  For usbhid the post_reset routine is also used for
reset_resume (duplicate method pointers); for the other drivers a new
reset_resume routine is added.  The change to hub.c looks bigger than
it really is, because mark_children_for_reset_resume() gets moved down
next to the new hub_reset_resume() routine.

A minor change to usb-storage makes the usb_stor_report_bus_reset()
routine acquire the host lock instead of requiring the caller to hold
it already.

This patch (as917) removes a now-unnecessary level of subroutine
nesting from hub.c.  Since usb_port_suspend() does nothing but call

Also included in the patch are a few cosmetic changes involving

686314cfbd USB: separate root and non-root suspend/resume
This patch (as916) completes the separation of code paths for suspend
and resume of root hubs as opposed to non-root devices.  Root hubs
will be power-managed through their bus_suspend and bus_resume
methods, whereas normal devices will use usb_port_suspend() and
usb_port_resume().

Changes to the hcd_bus_{suspend,resume} routines mostly represent
motion of code that was already present elsewhere.  They include:

	Adding debugging log messages,

	Setting the device state appropriately, and

	Adding a resume recovery time delay.

Changes to the port-suspend and port-resume routines in hub.c include:

	Removal of checks for root devices (since they will never
	be triggered), and

	Removal of checks for NULL or invalid device pointers (these
	were left over from earlier kernel versions and aren't needed
	at all).

Make sure gadgetfs userspace interface is properly exported:

 - Move <linux/usb_gadgetfs.h> to <linux/usb/gadgetfs.h>;
 - Export it using Kbuild;
 - Add an #include guard;
 - Correct some internal documentation;
 - Update struct layout so it's the same on 32/64 bit kernels.

ba02978a48 USB: ehci_fsl update for MPC831x support
For MPC831x support, change the ehci-fsl driver to preserve
bits set in platform code.  Add a common CONFIG_USB_EHCI_FSL
to indicate presence of Freescale EHCI SOC.  Add FSL_USB2_DR_OTG
operating mode support, thus both host and device can work for the
mini-ab receptacle.  Note: this doesn't enable OTG protocol
support.

CONFIG_USB_EHCI_BIG_ENDIAN_MMIO and CONFIG_USB_EHCI_BIG_ENDIAN_DESC in
the usb host Kconfig file and not in the platform Kconfig files.

97cd49ebf7 USB: ftdi_sio.c: Allow setting latency timer on FT232RL
The new FT232RL allows setting and getting the value of the latency
timer, like on the FT232BM. However, the driver will not create the
sysfs entries for the RL without this one-line patch. 

I have tested it on two systems with successful results.

20dfdad74a USB: rework C++-style comments
This patch (as911) replaces some C++-style commented-out debugging
lines in driver.c with a new "verbose debugging" macro.  It makes the
code look cleaner, and it's easier to turn the debugging on or off.
