In commit 8122de5460 ("dt-bindings: Convert vendor prefixes to
json-schema"), vendor-prefixes.txt has been converted to a DT schema.
Update the checkpatch.pl DT check to extract vendor prefixes from the new
vendor-prefixes.yaml file.

The purpose of Co-developed-by: is to give attribution to authors who
aren't already attributed by the From: tag, i.e. who aren't the nominal
patch author. Because Co-developed-by: is essentially a variation of
From:, it must be accompanied by a Signed-off-by: of the associated
co-author. To ease the burden of determining whether or not co-authors
have signed off, Co-developed-by and Signed-off-by: must be explicitly
paired, i.e. on consecutive lines for a given co-author.

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), ...)

This patch creates a deprecated_apis map, which allows such APIs to
be flagged with suggested replacements more compactly and straightforwardly.
It also uses this map to flag the old flavorful RCU APIs as deprecated,
suggesting their vanilla-RCU counterparts as replacements.

[ paulmck: Merged with earlier less-deft approach. ]
__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)
if (trust_cpu && arch_init) {
