media: prefix header search paths with $(srctree)/
Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit

Convert to use vm_map_pages() to map range of kernel memory to user vma. vm_pgoff is treated in V4L2 API as a 'cookie' to select a buffer, not as a in-buffer offset by design and it always want to mmap a whole buffer from its beginning.

mm/gup: replace get_user_pages_longterm() with FOLL_LONGTERM
Pach series "Add FOLL_LONGTERM to GUP fast and use it". HFI1, qib, and mthca, use get_user_pages_fast() due to its performance advantages. These pages can be held for a significant time. But get_user_pages_fast() does not protect against mapping FS DAX pages. Introduce FOLL_LONGTERM and use this flag in get_user_pages_fast() which retains the performance while also adding the FS DAX checks. XDP has also shown interest in using this functionality.[1] In addition we change get_user_pages() to use the new FOLL_LONGTERM flag and remove the specialized get_user_pages_longterm call. [1] https://lkml.org/lkml/2019/3/19/939 "longterm" is a relative thing and at this point is probably a misnomer. This is really flagging a pin which is going to be given to hardware and can't move. I've thought of a couple of alternative names but I think we have to settle on if we are going to use FL_LAYOUT or something else to solve the "longterm" problem. Then I think we can change the flag to a better name. Secondly, it depends on how often you are registering memory. I have spoken with some RDMA users who consider MR in the performance path... For the overall application performance. I don't have the numbers as the tests for HFI1 were done a long time ago. But there was a significant advantage. Some of which is probably due to the fact that you don't have to hold mmap_sem. Finally, architecturally I think it would be good for everyone to use *_fast. There are patches submitted to the RDMA list which would allow the use of *_fast (they reworking the use of mmap_sem) and as soon as they are accepted I'll submit a patch to convert the RDMA core as well. Also to this point others are looking to use *_fast. As an aside, Jasons pointed out in my previous submission that *_fast and *_unlocked look very much the same. I agree and I think further cleanup will be coming. But I'm focused on getting the final solution for DAX at the moment. This patch (of 7): This patch starts a series which aims to support FOLL_LONGTERM in get_user_pages_fast(). Some callers who would like to do a longterm (user controlled pin) of pages with the fast variant of GUP for performance purposes. Rather than have a separate get_user_pages_longterm() call, introduce FOLL_LONGTERM and change the longterm callers to use it. This patch does not change any functionality. In the short term "longterm" or user controlled pins are unsafe for Filesystems and FS DAX in particular has been blocked. However, callers of get_user_pages_fast() were not "protected". FOLL_LONGTERM can _only_ be supported with get_user_pages[_fast]() as it requires vmas to determine if DAX is in use. NOTE: In merging with the CMA changes we opt to change the get_user_pages() call in check_and_migrate_cma_pages() to a call of __get_user_pages_locked() on the newly migrated pages. This makes the code read better in that we are calling __get_user_pages_locked() on the pages before and after a potential migration. As a side affect some of the interfaces are cleaned up but this is not the primary purpose of the series. In review[1] it was asked: <quote> > This I don't get - if you do lock down long term mappings performance > of the actual get_user_pages call shouldn't matter to start with. > > What do I miss? A couple of points. First "longterm" is a relative thing and at this point is probably a misnomer. This is really flagging a pin which is going to be given to hardware and can't move. I've thought of a couple of alternative names but I think we have to settle on if we are going to use FL_LAYOUT or something else to solve the "longterm" problem.

media: rcar-csi2: restart CSI-2 link if error is detected
Restart the CSI-2 link if the CSI-2 receiver detects an error during reception. The driver did nothing when a link error happened and the data flow simply stopped without the user knowing why. Change the driver to try and recover from errors by restarting the link and informing the user that something is not right. For obvious reasons it's not possible to recover from all errors (video source disconnected for example) but in such cases the user is at least informed of the error and the same behavior of the stopped data flow is retained.

media: omap_vout: potential buffer overflow in vidioc_dqbuf()
The "b->index" is a u32 the comes from the user in the ioctl. It hasn't
been checked. We aren't supposed to use it but we're instead supposed
to use the value that gets written to it when we call videobuf_dqbuf().
The videobuf_dqbuf() first memsets it to zero and then re-initializes it
inside the videobuf_status() function. It's this final value which we
want.
Hans Verkuil pointed out that we need to check the return from
videobuf_dqbuf(). I ended up doing a little cleanup related to that as
well.

media: atmel: atmel-isc: fix asd memory allocation
The subsystem will free the asd memory on notifier cleanup, if the asd is
added to the notifier.
However the memory is freed using kfree.
Thus, we cannot allocate the asd using devm_*
This can lead to crashes and problems.
To test this issue, just return an error at probe, but cleanup the
notifier beforehand.

media: atmel: atmel-isc: fix INIT_WORK misplacement
In case the completion function failes, unbind will be called
which will call cancel_work for awb_work.
This will trigger a WARN message from the workqueue.
To avoid this, move the INIT_WORK call at the start of the completion
function. This way the work is always initialized, which corresponds
to the 'always canceled' unbind code.

media: atmel: atmel-isc: limit incoming pixels per frame
This will limit the incoming pixels per frame from the sensor. Currently, the ISC will stop sampling the frame only when the vsync/hsync are detected. If we misconfigure the resolution in the sensor w.r.t. resolution in the ISC, the buffer used for DMA in the ISC will be smaller than the number of pixels that the ISC DMA engine will copy. In this case it happens that the DMA will overwrite parts of the memory which should not be written, leading to memory corruption. To avoid this situation, use the PFE CFG1 and PFE CFG2 registers, which crop the incoming frame to the resolution that we configure. This way the DMA engine will never write more data than we expect it to.

media: platform: meson: Add Amlogic Meson G12A AO CEC Controller driver
The Amlogic G12A SoC embeds a second CEC controller with a totally different design. The two controller can work in the same time since the CEC line can be set to two different pins on the two controllers. This second CEC controller is documented as "AO-CEC-B", thus the registers will be named "CECB_" to differentiate with the other AO-CEC driver. Unlike the other AO-CEC controller, this one takes the Oscillator clock as input and embeds a dual-divider to provide a precise 32768Hz clock for communication. This is handled by registering a clock in the driver. Unlike the other AO-CEC controller, this controller supports setting up to 15 logical addresses and supports the signal_free_time settings in the transmit function. Unfortunately, this controller does not support "monitor" mode.

media: cros-ec-cec: decrement HDMI device refcount
The CrosEC CEC driver never decremented the HDMI device refcount. CEC drivers only need the HDMI device pointer as a key in the notifier list, it never accesses the device, so there is no need to keep a reference.

media: cec-notifier: add cec_notifier_parse_hdmi_phandle helper
Add helper function to parse the DT for the hdmi-phandle property and return the corresponding struct device pointer. It takes care to avoid increasing the device refcount since all we need is the device pointer. This pointer is used in the notifier list as a key, but it is never accessed by the CEC driver.
