Convert livepatch documentation to ReST format. The changes
are mostly trivial, as the documents are already on a good
shape. Just a few markup changes are needed for Sphinx to
properly parse the docs.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- The in-file TOC becomes a comment, in order to skip it from the
output, as Sphinx already generates an index there.
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

|
Description:
|
|
A writable attribute that allows administrator to affect the
|
|
course of an existing transition. Writing 1 clears
|
|
TIF_PATCH_PENDING flag of all tasks and thus forces the tasks to
|
|
the patched or unpatched state. Administrator should not
|
|
use this feature without a clearance from a patch
|
|
distributor. Removal (rmmod) of patch modules is permanently
|
|
disabled when the feature is used. See
|
|
Documentation/livepatch/livepatch.rst for more information.

The function directory contains attributes regarding the
|
|
properties and state of the patched function.
|
|
|
|
The directory name contains the patched function name and a
|
|
sympos number corresponding to the nth occurrence of the symbol
|
|
name in kallsyms for the patched object.
|
|
|
|
There are currently no such attributes.
