Christophe JAILLET 3795f46b83 mm/frontswap.c: use non-atomic '__set_bit()' when possible 
The 'a' and 'b' bitmaps are local to this function, so no concurrent
access can occur.  So the non-atomic '__set_bit()' can be used to save a
few cycles.

README 

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.
