for return value checks.
I've also included removal of some extra semicolons,

ARM: OMAP4/AM335x: hwmod: fix disable_module regression in hardreset handling
Commit
eb05f691290e99ee0bd1672317d6add789523c1e ("ARM: OMAP: hwmod:
partially un-reset hwmods might not be properly enabled") added code
to skip the IP block disable sequence if all of the block's hardreset
lines weren't asserted. But this did not handle the case when no
hardreset lines were associated with a module, which is the general
case. In that situation, the IP block disable would be skipped. This
is likely to cause PM regressions.
So, modify _omap4_disable_module() and _am33xx_disable_module() to
only bail out early if there are any hardreset lines asserted. And
move the AM33xx test above the actual module disable code to ensure
that the behavior is consistent.

- Preparation patches for the OMAP common clock framework conversion
- clkdev alias additions required by other drivers
- Performance Monitoring Unit (PMU) support for OMAP2, 3, and

- Preparation patches for the IOMMU runtime PM conversion
- Preparation patches for OMAP4 full-chip retention support

- New driver for "address decoder controller" for mvebu, which is a
piece of hardware that configures addressable devices and
peripherals. First user is the boot rom aperture on armada XP
since it is needed for SMP support.
- New device tree bindings for peripherals such as gpio-fan, iconnect

Merge branch 'v4l_for_linus' of git://git./linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
"The first part of the media updates for Kernel 3.7.
This series contain:
- A major tree renaming patch series: now, drivers are organized
internally by their used bus, instead of by V4L2 and/or DVB API,
providing a cleaner driver location for hybrid drivers that
implement both APIs, and allowing to cleanup the Kconfig items and
make them more intuitive for the end user;
- Media Kernel developers are typically very lazy with their duties
of keeping the MAINTAINERS entries for their drivers updated. As
now the tree is more organized, we're doing an effort to add/update
those entries for the drivers that aren't currently orphan;
- Several DVB USB drivers got moved to a new DVB USB v2 core; the new
core fixes several bugs (as the existing one that got bitroted).
Now, suspend/resume finally started to work fine (at least with
some devices - we should expect more work with regards to it);
- added multistream support for DVB-T2, and unified the API for
DVB-S2 and ISDB-S. Backward binary support is preserved;
- as usual, a few new drivers, some V4L2 core improvements and lots
of drivers improvements and fixes.
There are some points to notice on this series:
1) you should expect a trivial merge conflict on your tree, with the
removal of Documentation/feature-removal-schedule.txt: this series
would be adding two additional entries there. I opted to not
rebase it due to this recent change;
2) With regards to the PCTV 520e udev-related breakage, I opted to
fix it in a way that the patches can be backported to 3.5 even
without your firmware fix patch. This way, Greg doesn't need to
rush backporting your patch (as there are still the firmware cache
and firmware path customization issues to be addressed there).
I'll send later a patch (likely after the end of the merge window)
reverting the rest of the DRX-K async firmware request, fully
restoring its original behaviour to allow media drivers to
initialize everything serialized as before for 3.7 and upper.
3) I'm planning to work on this weekend to test the DMABUF patches
for V4L2. The patches are on my queue for several Kernel cycles,
but, up to now, there is/was no way to test the series locally.
I have some concerns about this particular changeset with regards
to security issues, and with regards to the replacement of the old
VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
GPU drivers change. The Overlay API allows direct PCI2PCI
transfers from a media capture card into the GPU framebuffer, but
its API is crappy. Also, the only existing X11 driver that
implements it requires a XV extension that is not available
anymore on modern drivers. The DMABUF can do the same thing, but
with it is promising to be a properly-designed API. If I can
successfully test this series and be happy with it, I should be
asking you to pull them next week."

"There are three main parts:
(1) I found I needed some more fixups in the wake of testing Arm64

__KERNEL__ splitting needed to take place in Arm64.
(2) I found that c6x was missing some __KERNEL__ guards in its
asm/signal.h. Mark Salter pointed me at a tree with a patch to
remove that file entirely and use the asm-generic variant instead.
(3) Lastly, m68k turned out to have a header installation problem due
to it lacking a kvm_para.h file.
The conditional installation bits for linux/kvm_para.h, linux/kvm.h
and linux/a.out.h weren't very well specified - and didn't work if
an arch didn't have the asm/ version of that file, but there *was*
an asm-generic/ version.
It seems the "ifneq $((wildcard ...),)" for each of those three
headers in include/kernel/Kbuild is invoked twice during header
installation, and the second time it matches on the just installed
asm-generic/kvm_para.h file and thus incorrectly installs
linux/kvm_para.h as well.
Most arches actually have an asm/kvm_para.h, so this wasn't
detectable in those."

Pull ADM Xen support from Konrad Rzeszutek Wilk:
Features:
* Allow a Linux guest to boot as initial domain and as normal guests
on Xen on ARM (specifically ARMv7 with virtualized extensions). PV
console, block and network frontend/backends are working.
Bug-fixes:
* Fix compile linux-next fallout.
* Fix PVHVM bootup crashing.
The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
ARMv7 platforms.
The goal in implementing this architecture is to exploit the hardware
as much as possible. That means use as little as possible of PV
operations (so no PV MMU) - and use existing PV drivers for I/Os
(network, block, console, etc). This is similar to how PVHVM guests
operate in X86 platform nowadays - except that on ARM there is no need
for QEMU. The end result is that we share a lot of the generic Xen
drivers and infrastructure.
Details on how to compile/boot/etc are available at this Wiki:

default is too conservative, given the severe limitations it places on
usable AoE addresses. Storage virtualization and larger shelves have made
the old limitations too confining.
These changes make the dynamic block device minor numbers the default,

The static arrangement is still available with aoe_dyndevs=0, and the

aoe: support more AoE addresses with dynamic block device minor numbers
The ATA over Ethernet protocol uses a major (shelf) and minor (slot)
address to identify a particular storage target. These changes remove an
artificial limitation the aoe driver imposes on the use of AoE addresses.
For example, without these changes, the slot address has a maximum of 15,
but users commonly use slot numbers much greater than that.
The AoE shelf and slot address space is often used sparsely. Instead of
using a static mapping between AoE addresses and the block device minor
number, the block device minor numbers are now allocated on demand.

tAdd adds the ability to work with large packets composed of a number of
segments, using the scatter gather feature of the block layer (biovecs)
and the network layer (skb frag array). The motivation is the performance

using the network card's scatter gather feature.
Users of the out-of-tree aoe driver already had these changes, but since
early 2011, they have complained of increased memory utilization and
higher CPU utilization during heavy writes.[1] The commit below appears
related, as it disables scatter gather on non-IP protocols inside the
