This patch moves Exynos PM domain code to use the new generic PM domain
look-up framework introduced in previous patches, thus also allowing
the new code to be compiled with CONFIG_ARCH_EXYNOS.
This patch was originally submitted by Tomasz Figa when he was employed
by Samsung.

This patch introduces generic code to perform PM domain look-up using
device tree and automatically bind devices to their PM domains.
Generic device tree bindings are introduced to specify PM domains of
devices in their device tree nodes.
Backwards compatibility with legacy Samsung-specific PM domain bindings
is provided, but for now the new code is not compiled when
CONFIG_ARCH_EXYNOS is selected to avoid collision with legacy code.
This will change as soon as the Exynos PM domain code gets converted to
use the generic framework in further patch.

The example code provided with the i2c device interface documentation
won't compile since it uses the reserved word "register" to name a

The compiler fails with this error message:
error: expected identifier or '(' before '=' token

Rename the variable "register" to simply "reg" in the example code.

Here's the weekly batch of fixes from arm-soc.
The delta is a largeish negative delta, due to revert of SMP support for Broadcom's
STB SoC -- it was accidentally merged before some issues had been addressed, so they
will make a new attempt for 3.18. I didn't see a need for a full revert of the whole
platform due to this, we're keeping the rest enabled.
The rest is mostly:
* A handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
* Some MTD/NAND fixes for OMAP
* Minor DT fixes for shmobile
* Warning fix for UP builds on vexpress/spc
There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
so it can boot. Drivers and the rest had landed for 3.17, and it's small
and isolated so it made sense to pick up now even if it's not a bugfix.

For v3.14 and prior, 1-bit Hamming code ECC via software was the
default choice for some boards e.g. 3430sdp.
Commit ac65caf514 in v3.15 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.
This ECC layout change causes NAND filesystems created in v3.14
and prior to be unusable in v3.15 and later. So don't mark "sw" scheme
as deperecated and support it.

The below patch improves the documentation for the gpio-property. Stephen
Warren has a good example here:
https://github.com/swarren/linux-tegra/commit/09789801
trackpad@4b {
compatible = "atmel,maxtouch";
reg = <0x4b>;
interrupt-parent = <&gpio>;
interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>;
linux,gpio-keymap = <0 0 0 BTN_LEFT>;
};
This maps BTN_LEFT to the 4th bit of the T19 message.

In case the Device Tree blob passed by the boot agent supplies both an
'interrupts-extended' and an 'interrupts' property in order to allow for
older kernels to be usable, prefer the new-style 'interrupts-extended'
property which conveys a lot more information.
This allows us to have bootloaders willingly maintaining backwards
compatibility with older kernels without entirely deprecating the
'interrupts' property.
Update the bindings documentation to describe a situation where both the
'interrupts-extended' and the 'interrupts' property are present, and
which one takes precedence over the other.

ability to build bluetooth modular, fix from Geert Uytterhoeven.
2) Several phy_node reference count bug fixes from Uwe Kleine-König.
3) Fix ucc_geth build failures, also from Uwe Kleine-König.

Borkmann.

Benc.

module is loaded or not, but there are generic dependencies that
matter wrt what can be expected as the SKB enters the stack.
Make the basic untagging generic code, and do it unconditionally.
From Vlad Yasevich.

mutex changes (which will also go to the 3.16 stable series).
Yan Zheng has several fixes in here for CephFS fixing ACL handling,
time stamps, and request resends when the MDS restarts.

Pull vfs updates from Al Viro:
"Stuff in here:
- acct.c fixes and general rework of mnt_pin mechanism. That allows
to go for delayed-mntput stuff, which will permit mntput() on deep
stack without worrying about stack overflows - fs shutdown will
happen on shallow stack. IOW, we can do Eric's umount-on-rmdir
series without introducing tons of stack overflows on new mntput()
call chains it introduces.
- Bruce's d_splice_alias() patches
- more Miklos' rename() stuff.
- a couple of regression fixes (stable fodder, in the end of branch)
and a fix for API idiocy in iov_iter.c.
There definitely will be another pile, maybe even two. I'd like to
get Eric's series in this time, but even if we miss it, it'll go right
in the beginning of for-next in the next cycle - the tricky part of
prereqs is in this pile"
