Change-Id: I34f83b15e9f9a59529f8d67a434577becf25d1a6
commit 13e45417cedbfc44b1926124b1846f5ee8c6ba4a upstream.
The usage of "capture group (...)" in the immediate condition after `&&`
results in `$1` being uninitialized. This issues a warning "Use of
uninitialized value $1 in regexp compilation at ./scripts/checkpatch.pl
line 2638".
I noticed this bug while running checkpatch on the set of commits from
v5.7 to v5.8-rc1 of the kernel on the commits with a diff content in
their commit message.
This bug was introduced in the script by commit e518e9a59e
("checkpatch: emit an error when there's a diff in a changelog"). It
has been in the script since then.
The author intended to store the match made by capture group in variable
`$1`. This should have contained the name of the file as `[\w/]+`
matched. However, this couldn't be accomplished due to usage of capture
group and `$1` in the same regular expression.
Fix this by placing the capture group in the condition before `&&`.
Thus, `$1` can be initialized to the text that capture group matches
thereby setting it to the desired and required value.

The conversion here is really trivial: just a bunch of title
markups and very few puntual changes is enough to make it to
be parsed by Sphinx and generate a nice html.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- 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.

Presently C99 style comments are removed unconditionally before actual
patch validity check happens. This is a problem for some third party
projects which use checkpatch.pl but do not allow C99 style comments.
This patch adds yet another variable, named C99_COMMENT_TOLERANCE. If
it is included in the --ignore command line or config file options list,
C99 comments in the patch are reported as errors.
Tested by processing a patch with a C99 style comment, it passes the
check just fine unless '--ignore C99_COMMENT_TOLERANCE' is present in
.checkpatch.conf.

Many new generic allocation functions like the kvmalloc family have been
added recently to the kernel.
The allocation functions test now includes:
o kvmalloc and variants
o kstrdup_const
o kmemdup_nul
o dma_alloc_coherent
o alloc_skb and variants
Add a separate $allocFunctions variable to help make the allocation
functions test a bit more readable.
Miscellanea:
o Use $allocFunctions in the unnecessary OOM message test and
add exclude uses with __GFP_NOWARN
o Use $allocFunctions in the unnecessary cast test
o Add the kvmalloc family to the preferred sizeof alloc style
foo = kvmalloc(sizeof(*foo), ...)

__ro_after_init is a specific __attribute__ that checkpatch does currently
not understand.
Add it to the known $Attribute types so that code that uses variables
declared with __ro_after_init are not thought to be a modifier type.
This appears as a defect in checkpatch output of code like:
static bool trust_cpu __ro_after_init = IS_ENABLED(CONFIG_RANDOM_TRUST_CPU);
[...]
if (trust_cpu && arch_init) {
where checkpatch reports:
ERROR: space prohibited after that '&&' (ctx:WxW)

Multiple line macro definitions where the arguments are separated by line
continuations can cause checkpatch to emit invalid syntax regex tests.
This can occur when a single argument is modified in a part of a patch.
For example: (to not add a diff in the commit message)
$ ./scripts/checkpatch.pl --git db023296f0
Unterminated \g... pattern in regex; <very long regex omitted>
And, the test does not work correctly when these arguments are all new as
the initial patch line addition "+" is used in the argument name.
Fix this by stripping the line continuations and any "+" from the list of
arguments.

checkpatch repeatedly uses a runtime minimum version check that validates
the minimum perl version required for a regex match by using a "$^V ge
5.10.0" runtime string match.
Only perform that minimum version test once and store the result to reduce
string matching time.
This reduces runtime execution time for patches or files with high line
counts.
An example runtime improvement:
new: $ time ./scripts/checkpatch.pl -f drivers/net/ethernet/intel/i40e/i40e_main.c > /dev/null

A struct with a bool member can have different sizes on various
architectures because neither bool size nor alignment is standardized.
So emit a message on the use of bool in structs only in .h files and not
.c files.
There is the real possibility that this test could have a false positive
when a bool is declared as an automatic, so limit the test to .h files
where the only false positive is for declarations in static inline
functions.

It may not be the actual real stable mailing list address, but the
stable scripts to actually pick up on the traditional way to mark stable
patches.
There are also reasons to explicitly avoid using the actual mailing list
address, since security patches with embargo dates generally do want the
stable marking, but don't want tools etc to mistakenly send the patch
out to the mailing list early.
So don't warn for things that are still actively used and explicitly
supported.
