I don't know. NetBSD developers are using %qd most of the time. When I
started porting our /usr/bin/ to solaris, I changed a lot of them to %lld.
I am not particularly concerned for the kernel code, but for userland.
I think that for maximum portability one should use:

	"%ulld", (unsigned long long) u_quad_t_variable_name
	"%lld", (long long) quad_t_variable_name
