The macros FOUR_ROUNDS_AND_SCHED and DO_4ROUNDS rely on an unexpected/undocumented behavior of the GNU assembler, which might change in the future (https://sourceware.org/bugzilla/show_bug.cgi?id=32073). M (1) (2) // 1 arg !? Future: 2 args M 1 + 2 // 1 arg !? Future: 3 args M 1 2 // 2 args Add parentheses around the single arguments to support future GNU assembler and LLVM integrated assembler (when the IsOperator hack from the following link is dropped).

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 reStructuredText 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.
