Merge tag 'docs-4.10' of git://git.lwn.net/linux

Pull documentation update from Jonathan Corbet:
 "These are the documentation changes for 4.10.

  It's another busy cycle for the docs tree, as the sphinx conversion
  continues. Highlights include:

   - Further work on PDF output, which remains a bit of a pain but
     should be more solid now.

   - Five more DocBook template files converted to Sphinx. Only 27 to
     go... Lots of plain-text files have also been converted and
     integrated.

   - Images in binary formats have been replaced with more
     source-friendly versions.

   - Various bits of organizational work, including the renaming of
     various files discussed at the kernel summit.

   - New documentation for the device_link mechanism.

  ... and, of course, lots of typo fixes and small updates"

-Welcome to The Linux Kernel's documentation!
-============================================
+Welcome to The Linux Kernel's documentation
+===========================================
 
-Contents:
+This is the top level of the kernel's documentation tree.  Kernel
+documentation, like the kernel itself, is very much a work in progress;
+that is especially true as we work to integrate our many scattered
+documents into a coherent whole.  Please note that improvements to the
+documentation are welcome; join the linux-doc list at vger.kernel.org if
+you want to help out.
+
+User-oriented documentation
+---------------------------
+
+The following manuals are written for *users* of the kernel — those who are
+trying to get it to work optimally on a given system.

+
+Introduction to kernel development
+----------------------------------
+
+These manuals contain overall information about how to develop the kernel.
+The kernel community is quite large, with thousands of developers
+contributing over the course of a year.  As with any large community,
+knowing how things are done will make the process of getting your changes
+merged much easier.

+
+Kernel API documentation
+------------------------
+
+These books get into the details of how specific kernel subsystems work
+from the point of view of a kernel developer.  Much of the information here
+is taken directly from the kernel source, with supplemental material added
+as needed (or at least as we managed to add it — probably *not* all that is
+needed).
