Make use of CONFIG_FUNCTION_ALIGNMENT which was introduced with commit
d49a062621 ("arch: Introduce CONFIG_FUNCTION_ALIGNMENT").
Select FUNCTION_ALIGNMENT_8B for gcc in order to reflect gcc's default
function alignment. For all other compilers, which is only clang, select
a function alignment of 16 bytes which reflects the default function
alignment for clang.
Also change the __ALIGN define to follow whatever the value of
CONFIG_FUNCTION_ALIGNMENT is. This makes sure that the alignment of C and
assembler functions is the same.
In result everything still uses the default function alignment for both
compilers. However in addition this is now also true for all assembly
functions, so that all functions have a consistent alignment.

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.
