This is needed for the future (post make-4.4.1) versions of gnu make. Starting from https://git.savannah.gnu.org/cgit/make.git/commit/?id=07fcee35f058a876447c8a021f9eb1943f902534 gnu make won't allow conditionals to follow recipe prefix. For example there is a tab followed by ifeq on line 324 in the root Makefile. With the new make this conditional causes the following $ make cpu.o /home/dgoncharov/src/linux-kbuild/Makefile:2063: *** missing 'endif'. Stop. make: *** [Makefile:240: __sub-make] Error 2 This patch replaces tabs followed by conditionals with 8 spaces. See https://savannah.gnu.org/bugs/?64185 and https://savannah.gnu.org/bugs/?64259 for details.

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.
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.
