I would like to replace Kyungmin Park, who is no longer interested in
maintaining S5P-CEC driver. I have access to various Exynos boards. I also
already did some tests of this driver and helped enabling it on various
Exynos boards. The driver itself is no longer in staging, so lets fix the
path too and add DT bindings file pattern match. Also change the mailing
list from ARM generic to Samsung SoC specific to get more attention and
easier review in the future.

[media] v4l2-core: Use kvmalloc() for potentially big allocations
There are multiple places where arrays or otherwise variable sized
buffer are allocated through V4L2 core code, including things like
controls, memory pages, staging buffers for ioctls and so on. Such
allocations can potentially require an order > 0 allocation from the
page allocator, which is not guaranteed to be fulfilled and is likely to
fail on a system with severe memory fragmentation (e.g. a system with
very long uptime).
Since the memory being allocated is intended to be used by the CPU
exclusively, we can consider using vmalloc() as a fallback and this is
exactly what the recently merged kvmalloc() helpers do. A kmalloc() call
is still attempted, even for order > 0 allocations, but it is done
with __GFP_NORETRY and __GFP_NOWARN, with expectation of failing if
requested memory is not available instantly. Only then the vmalloc()
fallback is used. This should give us fast and more reliable allocations
even on systems with higher memory pressure and/or more fragmentation,
while still retaining the same performance level on systems not
suffering from such conditions.
While at it, replace explicit array size calculations on changed
allocations with kvmalloc_array().
Purposedly not touching videobuf1, as it is deprecated, has only few
users remaining and would rather be seen removed instead.

[media] davinci: vpif: adaptions for DT support
The davinci VPIF is a single hardware block, but the existing driver
is broken up into a common library (vpif.c), output (vpif_display.c) and
intput (vpif_capture.c).
When migrating to DT, to better model the hardware, and because
registers, interrupts, etc. are all common,it was decided to
have a single VPIF hardware node[1].
Because davinci uses legacy, non-DT boot on several SoCs still, the
platform_drivers need to remain. But they are also needed in DT boot.
Since there are no DT nodes for the display/capture parts in DT
boot (there is a single node for the parent/common device) we need to
create platform_devices somewhere to instantiate the platform_drivers.
When VPIF display/capture are needed for a DT boot, the VPIF node
will have endpoints defined for its subdevs. Therefore, vpif_probe()
checks for the presence of endpoints, and if detected manually creates
the platform_devices for the display and capture platform_drivers.

[media] media: platform: rcar_drif: Add DRIF support
This patch adds Digital Radio Interface (DRIF) support to R-Car Gen3 SoCs.
The driver exposes each instance of DRIF as a V4L2 SDR device. A DRIF
device represents a channel and each channel can have one or two
sub-channels respectively depending on the target board.
DRIF supports only Rx functionality. It receives samples from a RF
frontend tuner chip it is interfaced with. The combination of DRIF and the
tuner device, which is registered as a sub-device, determines the receive
sample rate and format.
In order to be compliant as a V4L2 SDR device, DRIF needs to bind with
the tuner device, which can be provided by a third party vendor. DRIF acts
as a slave device and the tuner device acts as a master transmitting the
samples. The driver allows asynchronous binding of a tuner device that
is registered as a v4l2 sub-device. The driver can learn about the tuner
it is interfaced with based on port endpoint properties of the device in
device tree. The V4L2 SDR device inherits the controls exposed by the
tuner device.
The device can also be configured to use either one or both of the data
pins at runtime based on the master (tuner) configuration.

Add a new capability CEC_CAP_NEEDS_HPD. If this capability is set
then the hardware can only use CEC if the HDMI Hotplug Detect pin

where it is possible to transmit messages even if no hotplug signal is
present (needed for some displays that turn off the HPD when in standby,
but still have CEC enabled).
Typically hardware that needs this capability have the HPD wired to the CEC

mm: larger stack guard gap, between vmas
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.
