As it turns out more than just Armada 370 and XP support using GPIO
lines as PWM lines. For example the Armada 38x family has the same
hardware support. As such "marvell,armada-370-xp-gpio" for the
compatible string is a misnomer.
Change the compatible string to "marvell,armada-370-gpio" before the
driver makes it out of the -rc stage. This also follows the practice of
using only the first device family supported as part of the name.
Also update the documentation and comments in the code accordingly.

Stack guard page is a useful feature to reduce a risk of stack smashing
into a different mapping. We have been using a single page gap which
is sufficient to prevent having stack adjacent to a different mapping.
But this seems to be insufficient in the light of the stack usage in
userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
which is 256kB or stack strings with MAX_ARG_STRLEN.
This will become especially dangerous for suid binaries and the default
no limit for the stack size limit because those applications can be
tricked to consume a large portion of the stack and a single glibc call
could jump over the guard page. These attacks are not theoretical,
unfortunatelly.
Make those attacks less probable by increasing the stack guard gap
to 1MB (on systems with 4k pages; but make it depend on the page size
because systems with larger base pages might cap stack allocations in
the PAGE_SIZE units) which should cover larger alloca() and VLA stack
allocations. It is obviously not a full fix because the problem is
somehow inherent, but it should reduce attack space a lot.
One could argue that the gap size should be configurable from userspace,
but that can be done later when somebody finds that the new 1MB is wrong
for some special case applications. For now, add a kernel command line
option (stack_guard_gap) to specify the stack gap size (in page units).
Implementation wise, first delete all the old code for stack guard page:
because although we could get away with accounting one extra page in a
stack vma, accounting a larger gap can break userspace - case in point,
a program run with "ulimit -S -v 20000" failed when the 1MB gap was
counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
and strict non-overcommit mode.
Instead of keeping gap inside the stack vma, maintain the stack guard
gap as a gap between vmas: using vm_start_gap() in place of vm_start
(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
places which need to respect the gap - mainly arch_get_unmapped_area(),
and and the vma tree's subtree_gap support for that.

BackMerge tag 'v4.12-rc5' into drm-next
Linux 4.12-rc5 for nouveau fixes
An unusually big pull request for this merge window, with three notable
features:
- V3s display engine support. This is especially notable because it uses
a different display engine used on the newer Allwinner SoCs (H3, A64
and the likes) that will be quite easily supported now.
- HDMI support for the old Allwinner SoCs. This is enabled only on the
A10s for now, but should be really easy to extend to deal with A10, A20
and A31
- Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,
etc.). It currently ignores the second pipeline, but we can use the
dual-pipelines bindings. This will be useful to enable the display
pipeline while we work on the dual-pipeline.

The samsung s6e3hf2 panel is a 5.65" 1600x2560 AMOLED panel connected
using MIPI-DSI interfaces.
The s6e3hf2 is add to samsung,s6e3ha2.txt binding because it is a

Sync objects are new toplevel drm object, that contain a
pointer to a fence. This fence can be updated via command
submission ioctls via drivers.
There is also a generic wait obj API modelled on the vulkan
wait API (with code modelled on some amdgpu code).
These objects can be converted to an opaque fd that can be
passes between processes.

The Allwinner Timings Controller has two, mutually exclusive, channels.
When the binding has been introduced, it was assumed that there would be
only a single user per channel in the system.
While this is likely for the channel 0 which only connects to LCD displays,
it turns out that the channel 1 can be connected to multiple controllers in
the SoC (HDMI and TV encoders for example). And while the simultaneous use
of HDMI and TV outputs cannot be achieved, switching from one to the other
at runtime definitely sounds plausible.
Add an extra property, allwinner,tcon-channel, to specify for a given
endpoint which TCON channel it is connected to, while falling back to the
previous mechanism if that property is missing.

Hikey board. Together with a couple of DTS updates for the Hikey board we have
also extended the mmc pwrseq_simple, to support a new power-off-delay-us DT
property, as that was required to enable a graceful power off sequence for the
WiFi chip.

This contains a few HD-audio device-specific quirks and an endianess
fix for USB-audio, as well as the update of quirk model list
document. All fixes are small and trivial.
The document update could have been postponed, but it's a good thing
for user and has absolutely zero risk of breakage, so included here.
