Nico Huber 6e133fa470 linux_trampoline: Handle 64-bit framebuffer addresses 
To support full 64-bit addresses, there is a new field `ext_lfb_base`
since Linux 4.1. It is unclear, however, how a loader is supposed to
know if the kernel is compatible with this. Filling these previously
reserved bits doesn't hurt, but an old kernel would probably ignore
them and not know that it's handling a clipped, invalid address. So
we play safe, and only allow 64-bit addresses for kernels after the
2.15 version bump of the boot protocol.
