The ARM TWD interrupt is a private peripheral interrupt (PPI) and per
the ARM GIC documentation, whether the type for PPIs can be set is
IMPLEMENTATION DEFINED. For OMAP4 devices the PPI type cannot be set and
so when we attempt to set the type for the ARM TWD interrupt it fails.
This has done unnoticed because it fails silently and because we cannot
re-configure the type it has had no impact. Nevertheless fix the type
for the TWD interrupt so that it matches the hardware configuration.

EDMA was allocating DMA channels 32 and 33 for memcpy usage, out of which
channel 33 is actually used by DES crypto engine. This bad allocation of
the channel causes a crash in the DES crypto engine, as the channel
gets configured for memcpy usage instead of hardware <-> memory DMA.
Fixed by allocating DMA channels 58 and 59 for memcpy usage (I2C0 RX/TX),
which are not used by anybody.

the synctimer32k is clocked by 32K RTC OSC on AM43xx. But this 32K RTC OSC
is not available on epos boards which makes it fail to boot.
Synctimer32k can also be clocked by a peripheral PLL, so making this as

Commit 127500ccb7 ("ARM: OMAP2+: Only write the sysconfig on idle

updating it, only during idle path. But the patch is adding the
verification in the enable path. So, adding the check in a proper place
as per the commit description.
Not keeping this check during enable path as there is a chance of losing
context and it is safe to do on idle as the context of the register will
never be lost while the device is active.

KASAN needs to know whether the allocation happens in an IRQ handler.
This lets us strip everything below the IRQ entry point to reduce the
number of unique stack traces needed to be stored.
Move the definition of __irq_entry to <linux/interrupt.h> so that the
users don't need to pull in <linux/ftrace.h>. Also introduce the
__softirq_entry macro which is similar to __irq_entry, but puts the
corresponding functions to the .softirqentry.text section.

new device support in terms of LoC, but there has been some cleanup
in the core as well as the usual minor clk additions to various
drivers.
Core:
- parent tracking has been simplified
- CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
- of_clk_init() doesn't consider disabled DT nodes anymore
- clk_unregister() had an error path bug squashed
- of_clk_get_parent_count() has been fixed to only return unsigned ints
- HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
New Drivers:
- NXP LPC18xx creg
- QCOM IPQ4019 GCC
- TI dm814x ADPLL
- i.MX6QP
Updates:
- Cyngus audio clks found on Broadcom iProc devices
- Non-critical fixes for BCM2385 PLLs
- Samsung exynos5433 updates for clk id errors, HDMI support,
suspend/resume simplifications
- USB, CAN, LVDS, and FCP clks on shmobile devices
- sunxi got support for more clks on new SoCs and went through a minor
refactoring/rewrite to use a simpler factor clk construct
- rockchip added some more clk ids and added suport for fraction dividers

Code that uses no modular facilities whatsoever should not be
sourcing module.h at all, since that header drags in a bunch
of other headers with it.
Similarly, code that is not explicitly using modular facilities
like module_init() but only is declaring module_param setup
variables should be using moduleparam.h and not the larger
module.h file for that.
In making this change, we also uncover an implicit use of BUG()
in inline fcns within arch/arm/include/asm/xen/hypercall.h so
we explicitly source <linux/bug.h> for that file now.

For stm32, we have now added a Kconfig fragment, the first such
file on arch/arm. The purpose here is to have a shared defconfig
file that works for all boards, while the DRAM offset has to be
hardwired on NOMMU machines at compile time.
The Exynos defconfig changes depend on changes in the RTC tree,
so this is pulled in here, but has already been merged into 4.6 now.

Pull ARM updates from Russell King:
"Another mixture of changes this time around:
- Split XIP linker file from main linker file to make it more
maintainable, and various XIP fixes, and clean up a resulting
macro.
- Decompressor cleanups from Masahiro Yamada
- Avoid printing an error for a missing L2 cache
- Remove some duplicated symbols in System.map, and move
vectors/stubs back into kernel VMA
- Various low priority fixes from Arnd
- Updates to allow bus match functions to return negative errno
values, touching some drivers and the driver core. Greg has acked
these changes.
- Virtualisation platform udpates form Jean-Philippe Brucker.
- Security enhancements from Kees Cook
- Rework some Kconfig dependencies and move PSCI idle management code
out of arch/arm into drivers/firmware/psci.c
- ARM DMA mapping updates, touching media, acked by Mauro.
- Fix places in ARM code which should be using virt_to_idmap() so
that Keystone2 can work.

Pull networking updates from David Miller:
"Highlights:
1) Support more Realtek wireless chips, from Jes Sorenson.
2) New BPF types for per-cpu hash and arrap maps, from Alexei
Starovoitov.
3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
4) Allow the use of SO_REUSEPORT in order to do per-thread processing
of incoming TCP/UDP connections. The muxing can be done using a
BPF program which hashes the incoming packet. From Craig Gallek.
5) Add a multiplexer for TCP streams, to provide a messaged based
interface. BPF programs can be used to determine the message
boundaries. From Tom Herbert.
6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

During the review process of the UniPhier System Bus driver
(drivers/bus/uniphier.c), the current binding of the System Bus
Controller turned out to be no good. In order to make the driver
really usable, we have to switch over to the new binding defined by
Documentation/devicetree/bindings/bus/uniphier-system-bus.txt.
The old binding will be still supported for a while to keep the
backward compatibility.

This property is used in common by several boards. Move it to the
