Pull ARM updates from Russell King:
"Here's the updates for ARM for this merge window, which cover quite a
variety of areas.
There's a bunch of patch series from Will tackling various bugs like
the PROT_NONE handling, ASID allocation, cluster boot protocol and
ASID TLB tagging updates.
We move to a build-time sorted exception table rather than doing the
sorting at run-time, add support for the secure computing filter, and
some updates to the perf code. We also have sorted out the placement
of some headers, fixed some build warnings, fixed some hotplug
problems with the per-cpu TWD code."

Here's the big set of USB patches for 3.8-rc1.
Lots of USB host driver cleanups in here, and a bit of a reorg of the
EHCI driver to make it easier for the different EHCI platform drivers to
all work together nicer, which was a reduction in overall code. We also
deleted some unused firmware files, and got rid of the very old
file_storage usb gadget driver that had been broken for a long time.
This means we ended up removing way more code than added, always a nice
thing to see:
310 files changed, 3028 insertions(+), 10754 deletions(-)
Other than that, the usual set of new device ids, driver fixes, gadget
driver and controller updates and the like.
All of these have been in the linux-next tree for a number of weeks.

The Huawei E173 will normally appear as 12d1:1436 in Linux. But
the modem has another mode with different device ID and a slightly
different set of descriptors. This is the mode used by Windows like
this:
3Modem: USB\VID_12D1&PID_140C&MI_00\6&3A1D2012&0&0000
Networkcard: USB\VID_12D1&PID_140C&MI_01\6&3A1D2012&0&0001
Appli.Inter: USB\VID_12D1&PID_140C&MI_02\6&3A1D2012&0&0002
PC UI Inter: USB\VID_12D1&PID_140C&MI_03\6&3A1D2012&0&0003
All interfaces have the same ff/ff/ff class codes in this mode.

This patch (as1636) is a partial workaround for a hardware bug
affecting OHCI controllers by NVIDIA at least, maybe others too. When
the controller retires a Transfer Descriptor, it is supposed to add
the TD onto the Done Queue. But sometimes this doesn't happen, with
the result that ohci-hcd never realizes the corresponding transfer has
finished. Symptoms can vary; a typical result is that USB audio stops
working after a while.
The patch works around the problem by recognizing that TDs are always
processed in order. Therefore, if a later TD is found on the Done
Queue than all the earlier TDs for the same endpoint must be finished
as well.
Unfortunately this won't solve the problem in cases where the missing
TD is the last one in the endpoint's queue. A complete fix would
require a signficant amount of change to the driver.

This is a set of four bug fixes. The isci one is an obvious thinko (using
request buffer instead of response buffer) which causes a command to fail.
The three others are DIF/DIX updates which are required because they're part
of a series of ten patches, the other seven of which went into the block layer
during the merge window meaning our current DIF/DIX implementation is broken
without these three.

The old parameter "port" is useless for phy notify, as one usb
phy is only for one usb port. New parameter "speed" stands for
the device's speed which is on the port, this "speed" parameter
is needed at some platforms which will do some phy operations
according to device's speed.

At commit 925aa46ba963a4da6d8ee6ab1d04a02ffa8db62b, Richard Zhao
<richard.zhao@freescale.com> adds the phy notification callback
when port change occurs. In fact, this phy notification should
be added according to below rules:
1. Only set HW_USBPHY_CTRL.ENHOSTDISCONDETECT
during high speed host mode.
2. Do not set HW_USBPHY_CTRL.ENHOSTDISCONDETECT
during the reset and speed negotiation period.
3. Do not set HW_USBPHY_CTRL.ENHOSTDISCONDETECT
during host suspend/resume sequence.
Please refer: i.mx23RM(page: 413) for below rules.
http://www.freescale.com/files/dsp/doc/ref_manual/IMX23RM.pdf
Freescale i.MX SoC, i.mx23, i.mx28 and i.mx6(i.mx6SL does not
need to follow the 3rd rule) need to follow above rules.
Current code set connect notification (HW_USBPHY_CTRL.ENHOSTDISCONDETECT)
at hub_port_connect_change, it conflicts with above the 2th rule.
The correct notification setting method should be:
1. Set connect notify after the second bus reset.
2. Set disconnect notify after disconnection.

The real reason causes mx23 fail are:
- Calling mxs_phy_hw_init(mxs_phy) again at connection
- Error connect/disconnect nodity at hub.c
The coming patch will fix above two problems, Mike Thompson
tested his hardware works OK after commented out this delay
setting.
This reverts commit 363366cf61c544ea476f3d220f43a95cb03014f5.

Some devices (ex Nokia C7) simply don't respond at all when data is sent
to some of their USB interfaces. The data gets stuck in the TTYs queue
and sits there until close(2), which them blocks because closing_wait
defaults to 30 seconds (even though the fd is O_NONBLOCK). This is
rarely desired. Implement the standard mechanism to adjust closing_wait
and let applications handle it how they want to.
