Mauro says:
This patch series fix Sphinx to allow it to build the media
documentation as a PDF file.
The first patch is actually a bug fix: one of the previous patch
broke compilation for PDF as a hole, as it added an extra
parenthesis to a function call.
The second patch just removes a left over code for rst2pdf.
The other patches change from "pdflatex" to "xelatex" and address
several issues that prevent building the media books.
I think this patch series belong to docs-next. Feel free to merge
them there, if you agree. There's one extra patch that touches
Documentation/conf.py, re-adding the media book to the PDF build,
but IMHO this one would be better to be merged via the media tree,
after the fixes inside the media documentation to fix the build.
This extension will be used by the media books.
The name of the math image extension changed on Sphinx 1.4.x,
according with:
http://www.sphinx-doc.org/en/stable/ext/math.html#module-sphinx.ext.imgmath
Let's autodetect, to keep building with versions < 1.4.

Looks like rst2pdf is not robust enough, especially for large documents.
Use recursive make on the Sphinx generated makefile to convert latex to
pdf. The ugly detail is that pdf is generated into
Documentation/output/latex.
Unfortunately, the pdflatex build generates huge amounts of build log
noise, and also fails in the end. We'll fix that next.

Since commit 63a4cc2486, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

Merge tag 'pstore-v4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull pstore fixes from Kees Cook:
"Fixes for pstore ramoops driver to catch bad kfree() and to use better
DT bindings"
* tag 'pstore-v4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
ramoops: use persistent_ram_free() instead of kfree() for freeing prz
ramoops: use DT reserved-memory bindings
Pull more input updates from Dmitry Torokhov:
"Two new drivers for touchscreen controllers:
- Silead touchscreen controllers
- SiS 9200 family touchscreen controllers
and a few driver fixes"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: silead - remove some dead code
Input: sis-i2c - select CONFIG_CRC_ITU_T
Input: add driver for SiS 9200 family I2C touchscreen controllers
Input: ili210x - fix permissions on "calibrate" attribute
Input: elan_i2c - properly wake up touchpad on ASUS laptops
Input: add driver for Silead touchscreens
Input: elantech - fix debug dump of the current packet
Input: rotary_encoder - support binary encoding of states
Input: xpad - power off wireless 360 controllers on suspend
Input: i8042 - break load dependency between atkbd/psmouse and i8042
Input: synaptics-rmi4 - do not check for NULL when calling of_node_put()
Input: cros_ec_keyb - cleanup use of dev
Instead of a ramoops-specific node, use a child node of /reserved-memory.
This requires that of_platform_device_create() be explicitly called
for the node, though, since "/reserved-memory" does not have its own
"compatible" property.
