No, as you want to _disable_ ARCH_HAS_FAST_FFS / _enable_
CPU_NO_EFFICIENT_FFS as soon as you're enabling support for a
CPU that doesn't support it.
Logical OR is easier in both the Kconfig and C preprocessor languages
than logical NAND.
E.g. in Kconfig, a CPU core not supporting it can just select
CPU_NO_EFFICIENT_FFS.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
