Drop the value-mask decomposition technique and adopt straightforward long-multiplication with a twist: when LSB(a) is uncertain, find the two partial products (for LSB(a) = known 0 and LSB(a) = known 1) and take a union. Experiment shows that applying this technique in long multiplication improves the precision in a significant number of cases (at the cost of losing precision in a relatively lower number of cases).

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.
