git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Add Exynos4415 SoC support, some fixups and cleanups.
Summary:
- Resolve kernel lockup issue incurred by probe request in probe context.
. For this, it moves all register codes of sub drivers into init function
and adds component binding support for vidi driver.
- Add Exynos4415 SoC support.
- Make each manager and display object to be embedded
in each driver context.
- Fix and clean up FIMD and MIPI-DSI drivers.
- Clean up unnecesary or wrong descriptions.
- And trivial cleanups.

If TX channels are set to 4 and RX channels are set to less than 4,
using ethtool -L, the driver will try to initialize more RX channels
than it has allocated, causing an oops.
This fix only initializes the RX ring if it has been allocated.

After commit ca777eff51f7 ("tcp: remove dst refcount false sharing for
prequeue mode") we have to relax check against skb dst in
tcp_v[46]_send_reset() if prequeue dropped the dst.
If a socket is provided, a full lookup was done to find this socket,
so the dst test can be skipped.

This reverts commit 5195c14c8b27cc0b18220ddbf0e5ad3328a04187.
If the conntrack clashes with an existing one, it is left out of
the unconfirmed list, thus, crashing when dropping the packet and
releasing the conntrack since golden rule is that conntracks are
always placed in any of the existing lists for traceability reasons.

====================
Fix outer UDP checksums for IPv6 VXLAN tunnels
In testing against an older kernel I found a couple issues in the IPv6
VXLAN tunnel checksum logic for the outer UDP checksum.
First the default transitioned from using an outer checksum to not using
one. Second, sometime after that the checksum inputs were changed
resulting the checksum not being correct if it were computed.
These two issues prevented a ping from the newer kernel to the older one.
With these two changes applied I verified I was able to send traffic over
the VXLAN tunnel to a link partner on an older kernel.
The boolean flip fix can be submitted for 3.17 stable as well since the
patch that introduced the issue was included in that kernel.

In "vxlan: Call udp_sock_create" there was a logic error that resulted in
the default for IPv6 VXLAN tunnels going from using checksums to not using
checksums. Since there is currently no support in iproute2 for setting
these values it means that a kernel after the change cannot talk over a IPv6
VXLAN tunnel to a kernel prior the change.

The UDP checksum calculation for VXLAN tunnels is currently using the
socket addresses instead of the actual packet source and destination
addresses. As a result the checksum calculated is incorrect in some
cases.
Also uh->check was being set twice, first it was set to 0, and then it is
set again in udp6_set_csum. This change removes the redundant assignment
to 0.

In most situations it will be useful to have the old state passed to the
->atomic_update() callback. For example if a plane is being disabled the
new state's .crtc field will be NULL, but some drivers may rely on this
field to program the CRTCs registers.

suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to

The drm core can call the plane disable hook multiple times, which
means it can get called when plane->crtc is already NULL. That in turn
means we can't get at the implicit acquire ctx we use in the atomic
helpers for legacy entries points.
We could try to pass drm_modeset_legacy_acquire_ctx a drm_device
pointer so that it can cope with a NULL crtc. But that still doesn't
work since the cursor ioctls (remapped with the universal cursor plane
support code) only grabs the crtc locks. So the global acquire context
isn't set eitehr.
The real solution here would be to bite the bullet and wire up
explicit acquire context parameters to all relevant functions. We need
to do that anyway (to be able to get rid of some small allocations
which we can't cope with failing). But that's a lot of work and better
done once atomic has settled a bit.
So meanwhile just catch this case in the helper and bail out.

Especially with legacy cursor ioctls existing userspace assumes that
you can pile up lots of updates in one go. The super-proper way to
support this would be a special commit mode which overwrites the last
update. But getting there will be quite a bit of work.
Meanwhile do what pretty much all the drivers have done for the plane
update functions: Simply skip the vblank wait for the buffer cleanup
if the buffer is the same. Since the universal cursor plane code will
not recreate framebuffers needlessly this allows us to not slow down
legacy pageflip events while someone moves the cursor around.
v2: Drop the async plane update hunk from a previous attempt at this
issue.
v3: Fix up kerneldoc.
v4: Don't oops so badly. Reported by Jasper.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an
interrupt urb, but as there are a zillion different xpad devices out
there, let's cover out bases and handle both bulk and interrupt
endpoints just as easily.

Registering the Exynos DRM subdevices platform drivers in the probe
function is causing an infinite loop. Fix this by moving it to the
exynos_drm_init() function to register the drivers on module init.
Registering drivers in the probe functions causes a deadlock in the parent
device lock. See Grant Likely explanation on the topic:
"I think the problem is that exynos_drm_init() is registering a normal
(non-OF) platform device, so the parent will be /sys/devices/platform.
It immediately gets bound against exynos_drm_platform_driver which
calls the exynos drm_platform_probe() hook. The driver core obtains
device_lock() on the device *and on the device parent*.
Inside the probe hook, additional platform_drivers get registered.
Each time one does, it tries to bind against every platform device in
the system, which includes the ones created by OF. When it attempts to
bind, it obtains device_lock() on the device *and on the device
parent*.
Before the change to move of-generated platform devices into
/sys/devices/platform, the devices had different parents. Now both
devices have /sys/devices/platform as the parent, so yes they are
going to deadlock.
The real problem is registering drivers from within a probe hook. That
is completely wrong for the above deadlock reason. __driver_attach()
will deadlock. Those registrations must be pulled out of .probe().
Registering devices in .probe() is okay because __device_attach()
doesn't try to obtain device_lock() on the parent."

registered
- rebased it to exynos-drm-next

This reverts commit cea24824ab432f8acabb254d6805e9aa756de6af.
Moving subdriver probe to exynos_drm_platform_probe() was making
exynos_drm_device_subdrv_probe() fail because the platform data wasn't set
yet. It only gets set in exynos_drm_load.
We need to find a smarter way to fix this issue.

The patch replaces accesses to display->ctx pointer by container_of
construct. The field is removed as well as dpi was the last user of it.

exynos_drm_display is used by internal Exynos DRM framework for
representing encoder:connector pair. As it should be mapped 1:1 to dpi
private context it seems more reasonable to embed it directly in that context.
As a result further code simplification will be possible.
Moreover it will be possible to handle multiple dpi devices in the system.
