It includes a couple of fixes for i.MX6 GPC code to let the new kernel
be able to boot with old DTBs:
- Booting v4.1-rc kernel with old DTBs will fail with a fat warning
(require low-level debug to be seen), due to the adoption of stacked
IRQ domain. The first fix improves the situation by allowing kernel
boot up with old DTBs, although suspend/resume still breaks.
- Booting new kernel with old DTBs that do not have power-domain info
will result in a hang. The second patch fixes the hang by skipping
the kernel power-domain registration if DTB has no power-domain info.

ARM: dts: set display clock correctly for exynos4412-trats2
If the devicetree is too old and does not provide the regulator and clocks
for the power domain, we need to avoid registering the power domain.
Otherwise runtime PM will try to control the domain, which will lead to
machine hangs without the proper DT configuration data.
This restores functionality to the kernel 4.0 level if an old DT is
detected, where the power domain is constantly powered on.

The GPC rewrite to IRQ domains has been on the premise that it may break
suspend/resume for new kernels on old DT, but otherwise keep things working
from a user perspective. This was an accepted compromise to be able to move
the GIC cleanup forward.
What actually happened was that booting a new kernel on an old DT crashes
before even the console is up, so the user does not even see the warning
that the DT is too old. The warning message suggests that this has been
known before, which is clearly unacceptable.
Fix the early crash by mapping the GPC memory space if the IRQ controller
doesn't claim it. This keeps at least CPUidle and the needed CPU wakeup
workarounds working. With this fixed the system is able to boot up
properly minus the expected suspend/resume breakage.

ARM: dts: am335x-boneblack: disable RTC-only sleep
While Sitara AM335x SoCs are very close to OMAP SoCs, the 32-line GPIO
controllers are numbered from 0 on AM335x and from 1 on OMAP. But when
the configuration for the TI WLAN controllers was converted from
platform data to device tree, this detail was overlooked, as 10 boards
were using OMAP with the WL12xx and WL18xx controllers, and only one
was based on AM335x.
This invalid configuration prevents the WL1271 module on the AM335x
EVM-SK from notifying interrupts to the SoC, and breaks the wlan driver.
The DTS must be corrected to use the correct GPIO controller.

Two watchdog changes that came through different trees had a non
conflicting conflict, that is, one changed the semantics of a variable
but no actual code conflict happened. So the merge appeared fine, but
the resulting code did not behave as expected.
Commit 195daf665a ("watchdog: enable the new user interface of the
watchdog mechanism") changes the semantics of watchdog_user_enabled,
which thereafter is only used by the functions introduced by
b3738d2932 ("watchdog: Add watchdog enable/disable all functions").
There further appears to be a distinct lack of serialization between
setting and using watchdog_enabled, so perhaps we should wrap the
{en,dis}able_all() things in watchdog_proc_mutex.
This patch fixes a s2r failure reported by Michal; which I cannot
readily explain. But this does make the code internally consistent
again.

In commit 8ff16cf77c ("Documentation: devicetree: m25p80: add "nor-jedec"
binding"), we added a generic "nor-jedec" binding to catch all
mostly-compatible SPI NOR flash which can be detected via the READ ID
opcode (0x9F). This was discussed and reviewed at the time, however
objections have come up since then as part of this discussion:
http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074
It seems the parties involved agree that "jedec,spi-nor" does a better
job of capturing the fact that this is SPI-specific, not just any NOR
flash.
This binding was only merged for v4.1-rc1, so it's still OK to change
the naming.
At the same time, let's move the documentation to a better name.
Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the
documentation.

The xfstests test suite assumes that an attempt to collapse range on
the range (0, 1) will return EOPNOTSUPP if the file system does not
support collapse range. Commit 280227a75b: "ext4: move check under
lock scope to close a race" broke this, and this caused xfstests to
fail when run when testing file systems that did not have the extents

Dell XPS 13 (the AML on that machine uses the _REV return value to

NUMA balancing is meant to be disabled by default on UMA machines but
the check is using nr_node_ids (highest node) instead of
num_online_nodes (online nodes).
The consequences are that a UMA machine with a node ID of 1 or higher
will enable NUMA balancing. This will incur useless overhead due to
minor faults with the impact depending on the workload. These are the
impact on the stats when running a kernel build on a single node machine
whose node ID happened to be 1:
vanilla patched
NUMA base PTE updates 5113158 0
NUMA huge PMD updates 643 0
NUMA page range updates 5442374 0
NUMA hint faults 2109622 0
