Additionally, 'make pdfdocs' fails with e.g. 

/path/to/linux/Documentation/media/uapi/cec/cec-header.rst:9: SEVERE: Problems with "kernel-include" directive path:
InputError: [Errno 2] No such file or directory: '/path/to/linux/Documentation/output/cec.h.rst'.
/path/to/linux/Documentation/media/uapi/dvb/audio_h.rst:9: SEVERE: Problems with "kernel-include" directive path:
InputError: [Errno 2] No such file or directory: '/path/to/linux/Documentation/output/audio.h.rst'.
/path/to/linux/Documentation/media/uapi/dvb/ca_h.rst:9: SEVERE: Problems with "kernel-include" directive path:
InputError: [Errno 2] No such file or directory: '/path/to/linux/Documentation/output/ca.h.rst'.
/path/to/linux/Documentation/media/uapi/dvb/dmx_h.rst:9: SEVERE: Problems with "kernel-include" directive path:
InputError: [Errno 2] No such file or directory: '/path/to/linux/Documentation/output/dmx.h.rst'.

because the makefile hack is only done on htmldocs target.

Jani.
