No need to also verify KASAN here like powerpc and loongarch ?

Sorry, I didn't quite understand the question.
I've verified powerpc with KASAN enabled which selects KASAN_OUTLINE,
as far as I remember, and GENERIC mode.

The question is whether:

	select ARCH_DEFER_KASAN if STATIC_LINK

is enough ? Shouldn't it be:

	select ARCH_DEFER_KASAN if KASAN && STATIC_LINK

Like for powerpc and loongarch ?

I haven't tested LoongArch booting via QEMU, only tested compilation.
I guess, I need to test the boot, will try to learn how to do it for
qemu-system-loongarch64. Would be helpful LoongArch devs in CC can
assist as well.

STATIC_LINK is defined for UML only.
