* media: media/tuners: Use kmemdup rather than duplicating its implementationFuqian Huang2019-08-142-4/+2
| | | | | | | | | | | | kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

* media: Revert "media: vimc: propagate pixel format in the stream"Helen Koike2019-08-138-308/+342
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit b6c61a6c37317efd7327199bfe24770af3d7e799. The requested pixelformat is being propagated from the capture to the tpg in the sensor. This was a bad design choice, as we start having the following issues: * We set a pixelformat in the capture; * We set matching media bus formats in the subdevices pads; * Link validate looks fine (sizes matches, media bus formats matches); * Issue: if some of the subdevice doesn't know how to generate the requested pixelformat in the capture, then stream_on fails. This is bad because capture says it supports that pixelformat, everything looks fine, but it is not, and there is no way to find it out through the links. This patch was implemented so we could request any pixelformat from the pipeline regardeless of the media bus format configured between pads. Not all pixelformat can be mapped into a media bus code (e.g. multiplanar formats), so with this patch we could request those pixelformats from the tpg. Solution: map pixelformats to media bus codes as before, and implement conversions to other pixelformats in the capture to support multiplanar. So first step to this solution is to revert this patch.

Now also return the base address of the corresponding framebuffer that this overlays. - Missing ENUM/G/S_OUTPUT ioctls. - ROTATE/VFLIP controls were added when the HW didn't support them.

The filesystem-dax fix is tagged for stable as the implementation has been mistakenly throwing away all cow pages on any truncate or hole punch operation as part of the solution to coordinate device-dma vs truncate to dax pages. The device-dax change fixes up a regression this cycle from the introduction of a common 'internal per-cpu-ref' implementation.

I am wondering who needs to get rid of cow pages as well. I noticed one interesting side affect of this. I mount xfs with -o dax and mmaped a file with MAP_PRIVATE and wrote some data to a page which created cow page. Then I called fallocate() on that file to zero a page of file. fallocate() called dax_layout_busy_page() which unmapped cow pages as well and then I tried to read back the data I wrote and what I get is old data from persistent memory. I lost the data I had written. This read basically resulted in new fault and read back the data from persistent memory. This sounds wrong. Are there any users which need to unmap cow pages as well? If not, I am proposing changing it to not unmap cow pages. I noticed this while while writing virtio_fs code where when I tried to reclaim a memory range and that corrupted the executable and I was running from virtio-fs and program got segment violation." Dan: "In fact the unmap_mapping_range() in this path is only to synchronize against get_user_pages_fast() and force it to call back into the filesystem to re-establish the mapping. COW pages should be left untouched by dax_layout_busy_page()."
