Add smin/smax derivation from appropriate umin/umax values. Previously the logic was surprisingly asymmetric, trying to derive umin/umax from smin/smax (if possible), but not trying to do the same in the other direction. A simple addition to __reg64_deduce_bounds() fixes this. Added also generic comment about u64/s64 ranges and their relationship. Hopefully that helps readers to understand all the bounds deductions a bit better.

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.
