The __LINE__ macro creates challenges for binary diffing. When a .patch file adds or removes lines, it shifts the line numbers for all code below it. This can cause the code generation of functions using __LINE__ to change due to the line number constant being embedded in a MOV instruction, despite there being no semantic difference. Avoid such false positives by adding a fix-patch-lines script which can be used to insert a #line directive in each patch hunk affecting the line numbering. This script will be used by klp-build, which will be introduced in a subsequent patch.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
