Subject: checkpatch: check for incorrect permissions
From: Rabin Vincent <rabin.vincent@xxxxxxxxxxxxxx>

Throw an error when a source file has been given execute permissions using
the mode change line present in git diffs.  Also alow the filename
matching to use the "diff" line in addition to the "+++" line, since the
mode change lines appear before any "+++" lines.

[apw@xxxxxxxxxxxxx: simplified filename logic slightly, added tests]
