Pull drm u pdates from Dave Airlie:
"This is the main drm pull request for v4.12. Apart from two fixes
pulls, everything should have been in drm-next for at least 2 weeks.

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.
I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.
Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.
To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)

The interface to configure the LIF in the VSP1 requires adapting the
function prototype for any changes. This makes extending the interface
difficult.
Change the function prototype to pass a structure which can be easily
extended.
This changes the means of disabling the pipeline, by now passing a NULL
configuration rather than passing either a 0 width or height.

On Kernel 4.9, WARNINGs about doing DMA on stack are hit at
the dw2102 driver: one in su3000_power_ctrl() and the other in tt_s2_4600_frontend_attach().
Both were due to the use of buffers on the stack as parameters to
dvb_usb_generic_rw() and the resulting attempt to do DMA with them.
The device was non-functional as a result.
So, switch this driver over to use a buffer within the device state
structure, as has been done with other DVB-USB drivers.
Tested with TechnoTrend TT-connect S2-4600.

"A regression fix that makes the Siano driver to work again after the
CONFIG_VMAP_STACK change"
* tag 'media/v4.10-5' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
[media] siano: make it work again with CONFIG_VMAP_STACK
Reported as a Kaffeine bug:
https://bugs.kde.org/show_bug.cgi?id=375811
The USB control messages require DMA to work. We cannot pass
a stack-allocated buffer, as it is not warranted that the
stack would be into a DMA enabled area.
On Kernel 4.9, the default is to not accept DMA on stack anymore
on x86 architecture. On other architectures, this has been a
requirement since Kernel 2.2. So, after this patch, this driver
should likely work fine on all archs.

After removing DEBUG from mtk_vcodec_util.h, some build warnings are

^
It is because mtk_vcodec_debug() and mtk_vcodec_err() are defined as empty
macros. Without DEBUG definition, the variable for debugging is not used
anymore. Fixing build warnings by moving the assignment of the
variable to the argument of mtk_vcodec_debug() and mtk_vcodec_err().
Within the patch, build pass with/without DEBUG definition, and functions
still work fine.

If the USB driver is enabled but the demodulator is not, we get a link error:
ERROR: "zd1301_demod_get_dvb_frontend" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined!
ERROR: "zd1301_demod_get_i2c_adapter" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined!
Such a configuration obviously makes no sense, but we should not fail
the build. This tries to mimic what we have for other drivers by turning
the build failure into a runtime failure.
Alternatively we could use an unconditional 'select' or 'depends on' to enforce
a sane configuration.

Commit 17ce039b4e ("[media] cxusb: don't do DMA on stack")
added a kmalloc'ed bounce buffer for writes, but missed to do the same
for reads. As the read only happens after the write is finished, we can
reuse the same buffer.
As dvb_usb_generic_rw handles a read length of 0 by itself, avoid calling
it using the dvb_usb_generic_read wrapper function.

Apparently, 'count' can be negative here, which will then get turned
into a giant size argument for memcpy. Changing the sizes to 'unsigned
int' instead seems safe as we already check for maximum sizes, and it
also simplifies the code a bit.

I ran into a stack frame size warning because of the on-stack copy of
the USB device structure:
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c: In function 'dvb_usbv2_disconnect':
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c:1029:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Copying a device structure like this is wrong for a number of other reasons
too aside from the possible stack overflow. One of them is that the
dev_info() call will print the name of the device later, but AFAICT
we have only copied a pointer to the name earlier and the actual name
has been freed by the time it gets printed.
This removes the on-stack copy of the device and instead copies the
device name using kstrdup(). I'm ignoring the possible failure here
as both printk() and kfree() are able to deal with NULL pointers.
