[ Upstream commit 31299a5e0211241171b2222c5633aad4763bf700 ] This is a preparation for the upcoming GENMASK_U*() and BIT_U*() changes. After introducing those new macros, there will be a lot of scrolling between the #if, #else and #endif. Add a comment to the #else and #endif preprocessor macros to help keep track of which context we are in. Also, add new lines to better visually separate the non-asm and asm sections.

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.
