Commit Message

Oleksii Kurochko July 24, 2024, 3:31 p.m. UTC 
Introduces testing of some macros from <xen/bug.h>.

Also wraps this testing into SELF_TESTS config to not produce
a noise in the log related to functionality testing ( in the
current case, it is macros from xen/bug.h ) when CONFIG_SELF_TESTS
is disabled.
