commit 8d81ae05d0176da1c54aeaed697fa34be5c5575e upstream.
As of perl 5, version 26, subversion 0 (v5.26.0) some new warnings have
occurred when running checkpatch.
Unescaped left brace in regex is deprecated here (and will be fatal in
Perl 5.30), passed through in regex; marked by <-- HERE in m/^(.\s*){
<-- HERE \s*/ at scripts/checkpatch.pl line 3544.
Unescaped left brace in regex is deprecated here (and will be fatal in
Perl 5.30), passed through in regex; marked by <-- HERE in m/^(.\s*){
<-- HERE \s*/ at scripts/checkpatch.pl line 3885.
Unescaped left brace in regex is deprecated here (and will be fatal in
Perl 5.30), passed through in regex; marked by <-- HERE in
m/^(\+.*(?:do|\))){ <-- HERE / at scripts/checkpatch.pl line 4374.
It seems perfectly reasonable to do as the warning suggests and simply
escape the left brace in these three locations.

Rather than forcing authors of reverts to truncate the summary line
because the "Revert" prefix added pushes it over the character limit,
excuse reverts from this rule.

There are some very frequently used tags that checkpatch can look
for as an ending to the commit text rather than using a pattern,
which can generate false positives in the "no commit text" rule.

Fixed case when no warning generated for long subject line that is
wrapped to more than one line, and all lines are less than line limit.
New warning message added:
"non-blank line after summary line"
Now there are two warnings possible for the subject line, the original
line over limit and the new one. Depending on the error(s) any
combination of the two warnings are possible.
Commit text requirements now:
1) Must be less than 75 characters
2) Must be followed by blank line.

Improve parsing of multiline macros which run beyond the available
diff context. These beyond-the-horizon macros previously caused
two distinct naughty behaviors:
- The scanner, confused by the trailing backslash, would grab
the header of the next context hunk and treat it as the last
line of the preceding macro.
- The analyzer, unable to fully reduce the macro, would blame
the patch for submitting an unbalanced or unprotected macro.

checkpatch: Handle continuation headers.
Continuation headers baffle checkpatch, as it can only operate
on one line of context at a time. When continuation headers are found,
put them up with the header they're continuing so the whole thing
can be parsed in a single line of context.
checkpatch: Don't treat diffs as patches.
The patch-header cleanup code assumed that it would only ever
see patches, which was of course hogwash. This lead to crazy
results as it tried to wrap what it thought were continuation
lines at the beginnings of raw diffs.

The synchronize_rcu_expedited() and synchronize_sched_expedited()
expedited-grace-period primitives induce OS jitter, which can degrade

on any patch adding them.
Note that this patch does not warn on synchronize_srcu_expedited()
because it does not induce OS jitter, courtesy of its otherwise
much-maligned read-side memory barriers.
