Changeset f546ff0c ("Move our minimum Sphinx version to 1.7")
cleaned up some compatibility issues with previous Sphinx
versions, but it also dropped the PDF margin sets.

Without that, the media documentation won't build fine, as
the margins are too wide to display texts with monospaced
fonts.

While here, align the  "latex_elements = {" values, and add
a few other sphinxsetup configs in order to allow Sphinx to
wrap long lines on literal blocks.

Fixes: f546ff0c ("Move our minimum Sphinx version to 1.7")

X86 isn't the only architecture supporting NUMA_BALANCING. ARM64, PPC,

On the other hand, setup_numabalancing() is implemented in mm/mempolicy.c
which doesn't depend on architectures.

When anonymous enums are used, the identifier is empty.

While, IMO, it should be avoided the usage of such enums,
adding support for it is not hard.

Currently, kernel-doc warns for function prototype parsing on the
presence of attributes "__attribute_const__" and "__flatten" in the
definition.

There are 166 occurrences in ~70 files in the kernel tree for
"__attribute_const__" and 5 occurrences in 4 files for "__flatten".

Out of 166, there are 3 occurrences in three different files with
"__attribute_const__" and a preceding kernel-doc; and, 1 occurrence in
./mm/percpu.c for "__flatten" with a preceding kernel-doc. All other
occurrences have no preceding kernel-doc.

Add support for  "__attribute_const__" and "__flatten" attributes.

A quick evaluation by running 'kernel-doc -none' on kernel-tree reveals
that no additional warning or error has been added or removed by the fix.

Marvell has an annoying habit of moving stuff around their web site
every full moon, and often just removing documents altogether.

At this point basically none but four of the links still works and even
those that work today weren't working for a long period of time
previously. That is a shame because (short of the product briefs) the
documents tend to be quite useful.

Let's replace them with known working versions of IA's Wayback Machine
