Added the clang compiler option -fno-sanitize-blacklist to the CC_FLAGS_CFI variable. Without this flag, the make dependecy list files produced by clang, have the cfi_blacklist.txt as their first dependency. The dependecy lists are produced by the -Wp,-MD,filename option (for example: -Wp,-MD,mm/.mmap.o.d). The dependency lists are processed by the scripts/basic/fixdeps.c program, and are transformed into the .o.cmd files (for example: mm/.mmap.o.cmd). That file is meant to have the source code of the file listed in the source_* make variable (for example: source_mm/mmap.o). Instead of that that variable refers to the full pathname to the cfi_blacklist.txt file. Furthermore, the deps_* make variable is not supposed to include the source code file but it does include it. The cfi_blacklist.txt file is not required by the use of CFI for the kernel, use of the -fno-sanitize-blacklist causes the .o.cmd file to have the correct values in its source_* and dep_* variables.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
