Patch 7 adds a new warning:

  WARNING: unknown config value 'kerneldoc_bin' in override, ignoring

It needs to be taken out of sphinx-build-wrapper; I've appended the
following patch to the series to deal with it.  I think I'll go ahead
and tack on a patch putting in the scripts/kernel-doc symlink, then I
guess it's ready to go.

Thanks,

jon

Subject: [PATCH] docs: sphinx-build-wrapper: stop setting kerneldoc_bin for
 Sphinx

Now that the Sphinx build does not use the kerneldoc_bin configuration
variable, we shouldn't try to set it in the build wrapper or we get a nifty
warning:

  WARNING: unknown config value 'kerneldoc_bin' in override, ignoring
