Hmm, the counter argument is that this is actually accurate if those
architectures
were to gain support in the future, but someone ran this on an older kernel...

Yeah, unless you have a better idea. Actually, even though Kconfig isn't user-
controllable, it's still there in the .config. So maybe something like this?
TEST_ASSERT(cap, "Dirty-ring not supported, check
CONFIG_HAVE_KVM_DIRTY_RING?");
That would at least give the user a breadcrumb to start with.
