Reject any mode with DRM_MODE_FLAG_BCAST. We have no code that even
checks for this flag hence it can't possibly do any good.
I think this maybe originated from fbdev where it was supposed to
indicate PAL/NTSC broadcast timings. I have no idea why those would
have to be identified by a flag rather than by just the timings
themselves. And then I assume it got copied into xfree86 for
fbdevhw, and later on it leaked into the randr protocol and kms uapi.
Since kms fbdev emulation never uses the corresponding fbdev flag
there should be no sane way for this to come back into kms via
userspace either.

drm/tegra: Changes for v4.16-rc1
The bulk of these changes are preparation work and addition of support
for Tegra186. Currently only HDMI output (the primary output on Jetson
TX2) is supported, but the hardware is also capable of doing DSI and
DisplayPort.
Tegra DRM now also uses the atomic commit helpers instead of the open-
coded variant that was only doing half its job. As a bit of a byproduct
of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos
property support.
Along the way there are also a few patches to clean up a few things and
fix minor issues.

Remove lagacy IPP driver
- This driver isn't used anymore so remove it. Marek is preparing new one
which includes completely rewritten API so this driver will be replaced
with the new version[1] later.
And cleanups.

Musl provides its own ethhdr struct definition. Add a guard to prevent
its definition of the appropriate musl header has already been included.
glibc does not implement this header, but when glibc will implement this
they can just define __UAPI_DEF_ETHHDR 0 to make it work with the
kernel.

libc-compat.h aims to prevent symbol collisions between uapi and libc
headers for each supported libc. This requires continuous coordination
between them.
The goal of this commit is to improve the situation for libcs (such as
musl) which are not yet supported and/or do not wish to be explicitly
supported, while not affecting supported libcs. More precisely, with
this commit, unsupported libcs can request the suppression of any
specific uapi definition by defining the correspondings _UAPI_DEF_*
macro as 0. This can fix symbol collisions for them, as long as the
libc headers are included before the uapi headers. Inclusion in the
other order is outside the scope of this commit.
All infrastructure in order to enable this fallback for unsupported
libcs is already in place, except that libc-compat.h unconditionally
defines all _UAPI_DEF_* macros to 1 for all unsupported libcs so that
any previous definitions are ignored. In order to fix this, this commit
merely makes these definitions conditional.
This commit together with the musl libc commit
http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964ff944fbb8258
fixes for example the following compiler errors when <linux/in6.h> is
included after musl's <netinet/in.h>:
./linux/in6.h:32:8: error: redefinition of 'struct in6_addr'
./linux/in6.h:49:8: error: redefinition of 'struct sockaddr_in6'
./linux/in6.h:59:8: error: redefinition of 'struct ipv6_mreq'
The comments referencing glibc are still correct, but this file is not
only used for glibc any more.

Exynos DRM IPP subsystem is in fact non-functional and frankly speaking
dead-code. This patch clearly marks that Exynos DRM IPP subsystem is
broken and never really functional. It will be replaced by a completely
rewritten API.
Exynos DRM IPP user-space API can be obsoleted for the following
reasons:
1. Exynos DRM IPP user-space API can be optional in Exynos DRM, so
userspace should not rely that it is always available and should have
a software fallback in case it is not there.
2. The only mode which was initially semi-working was memory-to-memory
image processing. The remaining modes (LCD-"writeback" and "output")
were never operational due to missing code (both in mainline and even
vendor kernels).
3. Exynos DRM IPP mainline user-space API compatibility for
memory-to-memory got broken very early by commit 083500baef ("drm:
remove DRM_FORMAT_NV12MT", which removed the support for tiled formats,
the main feature which made this API somehow useful on Exynos platforms
(video codec that time produced only tiled frames, to implement xvideo
or any other video overlay, one has to de-tile them for proper
display).
4. Broken drivers. Especially once support for IOMMU has been added,
it revealed that drivers don't configure DMA operations properly and in
many cases operate outside the provided buffers trashing memory around.
5. Need for external patches. Although IPP user-space API has been used
in some vendor kernels, but in such cases there were additional patches
applied (like reverting mentioned 083500baef patch) what means that
those userspace apps which might use it, still won't work with the
mainline kernel version.
We don't have time machines, so we cannot change it, but Exynos DRM IPP
extension should never have been merged to mainline in that form.
Exynos IPP subsystem and user-space API will be rewritten, so remove
current IPP core code and mark existing drivers as BROKEN.

nft_ct exposes this bit to userspace. This used to be
#define NF_CT_STATE_UNTRACKED_BIT (1 << (IP_CT_NUMBER + 1))
(IP_CT_NUMBER is 5, so this was 0x40)
.. but this got changed to 8 (0x100) when the untracked object got removed.
Replace this with a literal 6 to prevent further incompatible changes
in case IP_CT_NUMBER ever increases.

The existing format modifier definitions were merged prematurely, and
recent work has unveiled that the definitions are suboptimal in several
ways:
- The format specifiers, except for one, are not Tegra specific, but
the names don't reflect that.
- The number space is split into two, reserving 32 bits for some
"parameter" which most of the modifiers are not going to have.
- Symbolic names for the modifiers are not using the standard
DRM_FORMAT_MOD_* prefix, which makes them awkward to use.
- The vendor prefix NV is somewhat ambiguous.
Fortunately, nobody's started using these modifiers, so we can still fix
the above issues. Do so by using the standard prefix. Also, remove TEGRA
from the name of those modifiers that exist on NVIDIA GPUs as well. In
case of the block linear modifiers, make the "parameter" smaller (4
bits, though only 6 values are valid) and don't let that leak into any
of the other modifiers.
Finally, also use the more canonical NVIDIA instead of the ambiguous NV
prefix.
