From: Hauke Mehrtens @ 2018-09-17 21:31 UTC (permalink / raw)
  To: johannes; +Cc: backports, john, Hauke Mehrtens

This removes parts which were only used by subsystems which are not
included in backports any more, for example media, bluetooth and
Ethernet.
The patches which are removed in this commit are not applied to the
kernel tree anyway with the default configuration because non of the
files get copied. The freezer, media, regulator and sound parts were
only used by the already removed media drivers. The flow dissector file
is not copied any more.

-Commit c60520fa needs to be reverted for older kernels because
-although we can backport some new DMA changes some other
-larger changes ended up extending some core dma data
-structures, for details see bca0fa5f as an example. We're
-aided with this revert by having added vb2_mmap_pfn_range() to
-compat. The main reason to revert is usage of the new
-dma_mmap_coherent() and core changes required via
-bca0fa5f.

-    [media] v4l: vb2-dma-contig: let mmap method to use dma_mmap_coherent call
-    
-    Let mmap method to use dma_mmap_coherent call.  Moreover, this patch removes
-    vb2_mmap_pfn_range from videobuf2 helpers as it was suggested by Laurent
-    Pinchart.  The function is no longer used in vb2 code.
