[PATCH v5 00/16]Fix several bad kernel-doc markups

[Mauro Carvalho Chehab]

Kernel-doc has always be limited to a probably bad documented
rule:

The kernel-doc markups should appear *imediatelly before* the
function or data structure that it documents.

On other words, if a C file would contain something like this:

	/**
	 * foo - function foo
	 * @args: foo args
	 */
	static inline void bar(int args);

	/**
	 * bar - function bar
	 * @args: foo args
	 */
	static inline void foo(void *args);


The output (in ReST format) will be:

	.. c:function:: void bar (int args)

	   function foo

	**Parameters**

	``int args``
	  foo args


	.. c:function:: void foo (void *args)

	   function bar

	**Parameters**

	``void *args``
	  foo args

Which is clearly a wrong result.  Before this changeset, 
not even a warning is produced on such cases.

As placing such markups just before the documented
data is a common practice, on most cases this is fine.

However, as patches touch things, identifiers may be
renamed, and people may forget to update the kernel-doc
markups to follow such changes.

This has been happening for quite a while, as there are
lots of files with kernel-doc problems.

This series address those issues and add a file at the
end that will enforce that the identifier will match the
kernel-doc markup, avoiding this problem from
keep happening as time goes by.

This series is based on current upstream tree.

@maintainers: feel free to pick the patches and
apply them directly on your trees, as all patches on 
this series are independent from the other ones.

--

v5:
  - The completion.h patch was replaced by another one which drops
    an obsolete macro;
  - Some typos got fixed and review tags got added;
  - Dropped patches that were already merged at linux-next.

v4:

  - Patches got rebased and got some acks.

[PATCH v5 11/16] memblock: fix kernel-doc markups

[Mauro Carvalho Chehab]

Some identifiers have different names between their prototypes
and the kernel-doc markup.
