Actually SECTIONS_SHIFT is used in the kernel code, so the code comments
is strictly incorrect. And since commit bbeae5b05e ("mm: move page
flags layout to separate header"), SECTIONS_SHIFT definition has been
moved to include/linux/page-flags-layout.h, since code itself looks quite
straighforward, instead of moving the code comment into the new place as
well, we just simply remove it.
This also fixed a checkpatch complain derived from the original code:
WARNING: please, no space before tabs
+ * SECTIONS_SHIFT ^I^I#bits space required to store a section #$

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.
