The omap/omap3 and viu drivers are for 32 bit platforms only.
There, a pointer has 32 bits. Now that those drivers build
for 64 bits with COMPILE_TEST, they produce the following
warnings:

Passing uninitialized flags into device_prep_interleaved_dma is clearly
a bad idea, and we get a compiler warning for it:
drivers/media/platform/omap/omap_vout_vrfb.c: In function 'omap_vout_prepare_vrfb':
drivers/media/platform/omap/omap_vout_vrfb.c:273:5: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized]
It seems that the OMAP dmaengine ignores the flags, but we should
pick the right ones anyway. This sets the flags I guessed based
on what other drivers used, and Peter confirmed that they are the
right ones.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.
</script>
use Text::Tabs;
while (<>) {
if ($next ne "") {
$c=$_;
if ($c =~ /^\s+\"(.*)/) {

This removes the 'write' and 'force' from get_vaddr_frames() and
replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in
callers as use of this flag can result in surprising behaviour (and
hence bugs) within the mm subsystem.

- An unsafe kernel parameter 'lockless_register_fb' for debugging
problems happening while inside the console lock
- Small miscellaneous fixes & cleanups
- omapdss: add writeback support functions
- Separation of omapfb and omapdrm (see below)
About the separation of omapfb and omapdrm, see
http://permalink.gmane.org/gmane.comp.video.dri.devel/143151
for longer story. The short version:
omapfb and omapdrm have shared low level drivers (omapdss and panel
drivers), making further development of omapdrm difficult. After
these patches omapfb and omapdrm have their own versions of the
drivers, which are more or less direct copies for now but will diverge
soon.
This also means that omapfb (everything under drivers/video/fbdev/omap2/)
is now in maintenance mode, and all new development will be done for
omapdrm (drivers/gpu/drm/omapdrm/)"

Commit 38a073116525 ("[media] omap: be sure that MMU is there for
COMPILE_TEST") added a dependency on HAS_MMU. There's no Kconfig symbol
HAS_MMU. Use MMU instead.

instead of testing bools if they are false or true, just use
if (!foo) or if (foo). That makes the code easier to
read and shorter.
Also, properly initialize booleans with true or false.

The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.
To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.
The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.
To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

commit 348077b154357eec595068a3336ef6beb870e6f3 ("OMAPDSS: Add new DVI
Connector driver"), DVI outputs report a new display type of
OMAP_DISPLAY_TYPE_DVI instead of OMAP_DISPLAY_TYPE_DPI. Handle the new
type in the IRQ handler.

sleep_on and its variants are broken and going away soon. This changes
the omap vout driver to use wait_event_interruptible_timeout instead,
which fixes potential race where the dma is complete before we
schedule.

wait_event_interruptible_timeout in the commit msg, obvious typo]

When booting with DT, there's a crash when omapfb is probed. This is
caused by the fact that omapdss+DT is not yet supported, and thus
omapdss is not probed at all. On the other hand, omapfb is always
probed. When omapfb tries to use omapdss, there's a NULL pointer
dereference crash. The same error should most likely happen with omapdrm
and omap_vout also.
To fix this, add an "initialized" state to omapdss. When omapdss has
been probed, it's marked as initialized. omapfb, omapdrm and omap_vout
check this state when they are probed to see that omapdss is actually
there.

If no manager is connected to the vout device, the omapvid_init() function
fails. No error condition is checked, and the device is started. Later on,
when irq is serviced, a NULL pointer dereference occurs.
Also, the isr routine must be registered only if no error occurs, otherwise
the isr triggers without the proper setup, and the kernel oops again.
To prevent this, the error condition is checked, and the streamon function
exits with error. Also the isr registration call is moved after the setup
procedure is completed.

Walking rbtree while it's modified is a Bad Idea(tm); besides,
the result of find_vma() can be freed just as it's getting returned
to caller. Fortunately, it's easy to fix - just take ->mmap_sem a bit
earlier (and don't bother with find_vma() at all if virtp >= PAGE_OFFSET -
in that case we don't even look at its result).
While we are at it, what prevents VIDIOC_PREPARE_BUF calling
v4l_prepare_buf() -> (e.g) vb2_ioctl_prepare_buf() -> vb2_prepare_buf() ->
__buf_prepare() -> __qbuf_userptr() -> vb2_vmalloc_get_userptr() -> find_vma(),
AFAICS without having taken ->mmap_sem anywhere in process? The code flow
is bloody convoluted and depends on a bunch of things done by initialization,
so I certainly might've missed something...
