The transfer buffer of dev->interrupt is allocated in .probe path,
but not freed in .disconnet path, so mark the interrupt URB as
URB_FREE_BUFFER to free the buffer when the URB is destroyed.

Creating a VLAN interface on top of ucc_geth adds 4 bytes
to the frame and the HW controller is not prepared to
TX a frame bigger than 1518 bytes which is 4 bytes too
small for a full VLAN frame. Add 16 bytes which will handle
the a simple VLAN and leaves 12 bytes for future expansion.

Pull USB patches from Greg Kroah-Hartman:
"Here are two EHCI Tegra driver patches for your tree.
The first is a bit big, but the majority is just moving code around.
It is needed due to the other EHCI core changes that went in way back
in 3.4-rc1, so this driver will now properly handle suspend/resume, as
it was broken. The other one is a minor bugfix that resolves an

On SandyBridge IPS was entirely implemented in hardware and not reliant
on the driver monitoring power consumption and feeding back desired run
states, so the hardware is able to adapt quicker and more flexibly. Which
is a huge relief for us as we no longer have to carry empirically
derived magic algorithms.
Yet despite the advance in technology, the driver was still doing its
IPS polling on all machines. Restrict it to the only supported hardware,
Clarkdale/Arrandale.

The immediately preceding gpio_direction_output() already set the value,
so there's no need to repeat it. This also prevents gpio_set_value() from
WARNing when the GPIO is sleepable (e.g. is on an I2C expander); the set
direction API is always sleepable, but plain set_value isn't.

This patch (as1547) rearranges the Power Management parts of the
ehci-tegra driver to match the conventions used in other EHCI platform
drivers. In particular, the controller should not be powered down by
the root hub's suspend routine; the controller's power level should be
managed by the controller's own PM methods.
The end result of the patch is that the standard ehci_bus_suspend()
and ehci_bus_resume() methods can be used instead of special-purpose
routines. The driver now uses the standard dev_pm_ops methods instead
of legacy power management. Since there is no supported wakeup
mechanism for the controller, runtime suspend is forbidden by default
(this can be overridden via sysfs, if desired).
These adjustments are needed in order to make ehci-tegra compatible
with recent changes to the USB core. The core now checks the root
hub's status following bus suspend; if the controller is automatically
powered down during bus suspend then the check will fail and the root
hub will be resumed immediately. Doing the controller power-down in a
separate method avoids this problem.

Fixing the locking accidentally replaced a race in the scroll
lock handling with a deadlock. Turn it back into a race for
now.
The basic problem is that there are two paths into the tty
stop/start helpers. One via the tty layer ^S/^Q handling
where we need to take the kbd_event_lock and one via the
special keyboard handler for fn_hold where we already hold
it. Probably we need to split out into a separate LED lock
but for now just go back to the race as it's a bit close
to release.

Bug: The VLAN bit of the MAC RX Status Word is unreliable in several older
supported chips. Sometimes the VLAN bit is not set for valid VLAN packets
and also sometimes the VLAN bit is set for non-VLAN packets that came after
a VLAN packet. This results in a receive length error when VLAN hardware
tagging is enabled.
Fix: Variation on original fix proposed by Mirko.
The VLAN information is decoded in the status loop, and can be
applied to the received SKB there. This eliminates the need for the
separate tag field in the interface data structure. The tag has to
be copied and cleared if packet is copied. This version checked out
with vlan and normal traffic.
Note: vlan_tx_tag_present should be renamed vlan_tag_present, but that
is outside scope of this.

The driver calls cxgb_vlan_mode() from init_one(). This calls into
synchronize_rx(), which locks all the q locks, but the q locks are not
initialized until cxgb_up() -> setup_sge_qsets(). So move the call to
cxgb_vlan_mode() into cxgb_up(), after the call to setup_sge_qsets().
We also move the body of these functions up higher to avoid having to
a forward declaration.
This was found because of the lockdep warning:
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

With the support to bounce buffer added, the skb is coming as nonlinear in the
case of non-DDPed data frames for FCoE, which is mostly ok as the FCoE stack
would take care of that. However, for target mode, we have to set the FC CRC
and FC EOF field to allow the protocol stack to not drop the frame for the last
data frame of that sequence. So fix this by linearizing the skb first before
doing skb_put().

A common flaw in UEFI systems is a refusal to POST triggered by a malformed
boot variable. Once in this state, machines may only be restored by
reflashing their firmware with an external hardware device. While this is
obviously a firmware bug, the serious nature of the outcome suggests that
operating systems should filter their variable writes in order to prevent
a malicious user from rendering the machine unusable.

The patch also corrects 2 typos that incorrectly report why an error branch
is being taken.

"Here are a number of small USB fixes for 3.4-rc5.
Nothing major, as before, some USB gadget fixes. There's a crash fix
for a number of ASUS laptops on resume that had been reported by a
number of different people. We think the fix might also pertain to
other machines, as this was a BIOS bug, and they seem to travel to
different models and manufacturers quite easily. Other than that,
some other reported problems fixed as well."

Clearing bit 5 of CACHE_MODE_0 is necessary to prevent GPU hangs in
OpenGL programs such as Google MapsGL, Google Earth, and gzdoom when
using separate stencil buffers. Without it, the GPU tries to use the
LRA eviction policy, which isn't supported. This was supposed to be off
by default, but seems to be on for many machines.
This cannot be done in gen6_init_clock_gating with most of the other
workaround bits; the render ring needs to exist. Otherwise, the
register write gets dropped on the floor (one printk will show it
changed, but a second printk immediately following shows the value
reverts to the old one).

Pull Xen fixes from Konrad Rzeszutek Wilk:
"Some of these had been in existence since the 2.6.27 days, some since
3.0 - and some due to new features added in v3.4.
The one that is most interesting is David's one - in the low-level
assembler code we had be checking events needlessly. With his patch
now we do it when the appropriate flag is set - with the added benefit
that we can process events faster. Stefano's is fixing a mistake
where the Linux IRQ numbers were ACK-ed instead of the Xen IRQ,
resulting in missing interrupts. The other ones are bootup related
that can show up on various hardware."
- In the low-level assembler code we would jump to check events even if
none were present. This incorrect behavior had been there since
2.6.27 days!
- When using the fast-path for ACK-ing interrupts we were using the
Linux IRQ numbers instead of the Xen ones (and they can differ) and
missing interrupts in process.
- Fix bootup crashes when ACPI hotplug CPUs were present and they would
expand past the set number of CPUs we were allocated.
- Deal with broken BIOSes when uploading C-states to the hypervisor.
- Disable the cpuid check for MWAIT_LEAF if the ACPI PAD driver is
loaded. If the ACPI PAD driver is used it will crash, so lets not
export the functionality so the ACPI PAD driver won't load.

xen: correctly check for pending events when restoring irq flags

Pull build fixes for less mainstream architectures from Paul Gortmaker:
"These are fixes for frv(1), blackfin(2), powerpc(1) and xtensa(4).
Fortunately the touches are nearly all specific to files just used by
the arch in question. The two touches to shared/common files
[kernel/irq/debug.h and drivers/pci/Makefile] are trivial to assess as
no risk to anyone.
Half of them relate to xtensa directly. It was only when I fixed the
last xtensa issue that I realized that the arch has been broken for a
significant time, and isn't a specific v3.4 regression. So if you
wanted, we could leave xtensa lying bleeding in the street for a
couple more weeks and queue those for 3.5. But given they are no risk
to anyone outside of xtensa, I figured to just leave them in.
If you are OK with taking the xtensa fixes, then please pull to get:
- one last implicit include uncovered by system.h that is in a file
specific to just one powerpc defconfig. (I'd sync'd with BenH).
- fix an oversight in the PCI makefile where shared code wasn't being
compiled for ARCH=frv
- fix a missing include for GPIO in blackfin framebuffer.
- audit and tag endif in blackfin ezkit board file, in order to find
and fix the misplaced endif masking a block of code.
- fix irq/debug.h choice of temporary macro names to be more internal
so they don't conflict with names used by xtensa.
- fix a reference to an undeclared local var in xtensa's signal.c
- fix an implicit bug.h usage in xtensa's asm/io.h uncovered by my
removing bug.h from kernel.h
- fix xtensa to properly indicate it is using asm-generic/hardirq.h
in order to resolve the link error - undefined ack_bad_irq
The xtensa still fails final link as my latest binutils does something
evil when ld forward-relocates unlikely() blocks, but in theory people
who have older/valid toolchains could now use the thing."

This driver currently leaves elp_work behind when stopping, which
occasionally results in data corruption because work function ends
up accessing freed memory, typical symptoms of this are various
worker_thread crashes. Fix it by cancelling elp_work.
