When a command times out, the command ring is first aborted,
and then stopped. If the command ring is empty when it is stopped
the stop event will point to next command which is not yet set.
xHCI tries to handle this next event often causing an oops.
Don't handle command completion events on stopped cmd ring if ring is
empty.
This patch should be backported to kernels as old as 3.7, that contain
the commit b92cc66c047ff7cf587b318fe377061a353c120f "xHCI: add aborting
command ring function"

Pull tty/serial fixes from Greg KH:
"Here are some serial at tty driver fixes for 3.12-rc3
The serial driver fixes some kref leaks, documentation is moved to the
proper places, and the tty and n_tty fixes resolve some reported
regressions. There is still one outstanding tty regression fix that
isn't in here yet, as I want to test it out some more, it will be sent
for 3.12-rc4 if it checks out"

Commit 'tty: ar933x_uart: add device tree support
and binding documentation' introduced a new doc in
bindins/tty/serial.
According to a recent thread [1] on the linux-serial
list, the binding documentation of serial drivers
should be added into bindings/serial.
Move the documentation of qca,ar9330-uart to the
correct place.

Since commit b5dc0d10 (drm/imx: kill firstopen callback) the following probe
failure is seen:
[drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
[drm] No driver support for vblank timestamp query.
[drm] Initialized imx-drm 1.0.0 20120507 on minor 0
imx-ldb ldb.10: adding encoder failed with -16

imx-ipuv3-crtc: probe of imx-ipuv3-crtc.2 failed with error -16
imx-ipuv3-crtc imx-ipuv3-crtc.3: adding crtc failed with -16.
imx-ipuv3-crtc: probe of imx-ipuv3-crtc.3 failed with error -16
The reason for the probe failure is that now 'imxdrm->references' is incremented
early in imx_drm_driver_load(), so the following checks in imx_drm_add_crtc()
and imx_drm_add_encoder():
if (imxdrm->references) {
ret = -EBUSY;
goto err_busy;
}
,will always fail.
Instead of manually keeping the references in the imx-drm driver, let's use
drm->open_count.

The vt6656 is prone to resetting on the usb bus.
It seems there is a race condition and wpa supplicant is
trying to open the device via iw_handlers before its actually
closed at a stage that the buffers are being removed.
The device is longer considered open when the
buffers are being removed. So move ~DEVICE_FLAGS_OPENED
flag to before freeing the device buffers.

There seems to be race condition that the device is ndo_start_xmit
at a point where the device is closing and apTD is NULL resulting
in dead lock.
Add a NULL check to apTD and return NULL to calling functions.
This is more likely on 64 bit systems.

The put_device(dev) at the bottom of the loop of device_shutdown
may result in the dev being cleaned up. In device_create_release,
the dev is kfreed.
However, device_shutdown attempts to use the dev pointer again after
put_device by referring to dev->parent.
Copy the parent pointer instead to avoid this condition.
This bug was found on Chromium OS's chromeos-3.8, which is based on v3.8.11.
See bug report : https://code.google.com/p/chromium/issues/detail?id=297842
This can easily be reproduced when shutting down with
hidraw devices that report battery condition.
Two examples are the HP Bluetooth Mouse X4000b and the Apple Magic Mouse.
For example, with the magic mouse :
The dev in question is "hidraw0"
dev->parent is "magicmouse"
In the course of the shutdown for this device, the input event cleanup calls
a put on hidraw0, decrementing its reference count.
When we finally get to put_device(dev) in device_shutdown, kobject_cleanup
is called and device_create_release does kfree(dev).
dev->parent is no longer valid, and we may crash in
put_device(dev->parent).
This change should be applied on any kernel with this change :

In kobj_ns_current_may_mount the default should be to allow the
mount. The test is only for a single kobj_ns_type at a time, and unless
there is a reason to prevent it the mounting sysfs should be allowed.
Subsystems that are not registered can't have are not involved so can't
have a reason to prevent mounting sysfs.
This is a bug-fix to:
commit 7dc5dbc879bd0779924b5132a48b731a0bc04a1e
Author: Eric W. Biederman <ebiederm@xmission.com>
Date: Mon Mar 25 20:07:01 2013 -0700
sysfs: Restrict mounting sysfs
Don't allow mounting sysfs unless the caller has CAP_SYS_ADMIN rights
over the net namespace. The principle here is if you create or have
capabilities over it you can mount it, otherwise you get to live with
what other people have mounted.
Instead of testing this with a straight forward ns_capable call,
perform this check the long and torturous way with kobject helpers,
this keeps direct knowledge of namespaces out of sysfs, and preserves
the existing sysfs abstractions.

Unset init_clients_timer and amthif_stall_timers
in mei_reset in order to cancel timer ticking and hence
avoid recursive reset calls.

The client state transition may occur for example as result
of firmware initiated reset
Add mei_cl_is_transitioning wrapper to reduce the code

1. u8 counters are prone to hard to detect overflow:
make them unsigned long to match bit_ functions argument type
2. don't check me_clients_num for negativity, it is unsigned.
3. init all the me client counters from one place

This reverts commit de95ab53645a2f0015e0f68ee723f18dce2b8b51.
Markus Trippelsdorf reported that this commit broke 'perf top':
> I just see a gray screen with no text at all. Sometimes the
> following error messages are printed:
>
> *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0
> ***
> *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 ***
While this code is fixable, the commit itself fails on several levels:
- it should have been a separate helper function
- why the heck does it do strchr() twice
- it casts a const char * over into char *
- sloppy style
- it's not even a regression fix!
So lets revert it and re-try the patch in v3.13.

We still need an API exported by msm iommu driver (but not visible in
any public header anymore). For now, just declare the prototype
ourselves, but when msm iommu driver provides a better option, use that
instead.

This is a partial revert of c6cf7777a32da874fabec4fd1c2a579f0ba4e4dd.
We need to take into account the clk voltage dependencies of the
board. Not doing so can lead to stability issues on certain
boards if the clks exceed the levels in the dep tables.
DPM already takes that into account, so for optimal performance,
use DPM.
