Andy Shevchenko 7eece6917c lib: polynomial: move to math/ subfolder
Patch series "lib: polynomial: Move to math/ and clean up", v2.

While removing Baikal SoC and platform code pieces I found that this code
belongs to lib/math/ rather than generic lib/.  Hence the move and
followed up cleanups.


This patch (of 3):

The algorithm behind polynomial belongs to our collection of math
equations and expressions handling.  Move it to math/ subfolder where
others of the kind are located.

Geert Uytterhoeven bcda5fd344 math: make RATIONAL tristate
Patch series "math: RATIONAL and RATIONAL_KUNIT_TEST improvements".

This series makes the RATIONAL symbol tristate, so it is not forced
builtin if all users are modular, and makes the RATIONAL_KUNIT_TEST depend
on RATIONAL, to avoid enabling RATIONAL if there are no real users.

This patch (of 2):

All but one symbols that select RATIONAL are tristate, but RATIONAL itself
is bool.  Change it to tristate, so the rational fractions support code
can be modular if no builtin code relies on it.

Masami Hiramatsu d0676871fd lib: Make prime number generator independently selectable
Make prime number generator independently selectable from
kconfig. This allows us to enable CONFIG_PRIME_NUMBERS=m
and run the tools/testing/selftests/lib/prime_numbers.sh
without other DRM selftest modules.

Andy Shevchenko 2c64e9cb0b lib: Move mathematic helpers to separate folder
For better maintenance and expansion move the mathematic helpers to the
separate folder.

No functional change intended.

Note, the int_sqrt() is not used as a part of lib, so, moved to regular
obj.
