Subject: linux-next: manual merge of the drm-misc tree with Linus' tree

Hi all,

Today's linux-next merge of the drm-misc tree got a conflict in:


between commit:

  eae1760fc838 ("doc: update/fixup dma-buf related DocBook")

from Linus' tree and commit:

  ddac4b5a6c08 ("Documentation: add fence-array to kernel DocBook")

from the drm-misc tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Stephen Rothwell

 +       <para>
 +         The dma-buf subsystem provides the framework for sharing buffers
 +         for hardware (DMA) access across multiple device drivers and
 +         subsystems, and for synchronizing asynchronous hardware access.
 +       </para>
 +       <para>
 +         This is used, for example, by drm "prime" multi-GPU support, but
 +         is of course not limited to GPU use cases.
 +       </para>
 +       <para>
 +         The three main components of this are: (1) dma-buf, representing
 +         a sg_table and exposed to userspace as a file descriptor to allow
 +         passing between devices, (2) fence, which provides a mechanism
 +         to signal when one device as finished access, and (3) reservation,
 +         which manages the shared or exclusive fence(s) associated with
 +         the buffer.
