    Subject[PATCH v5 16/40] kasan: only build init.c for software modes
    From
    This is a preparatory commit for the upcoming addition of a new hardware
    tag-based (MTE-based) KASAN mode.

    The new mode won't be using shadow memory, so only build init.c that
    contains shadow initialization code for software modes.

    No functional changes for software modes.
