Clearly the cpu can do 64bit. It might not do it well or it might be
broken but the cpu must have the 64bit feature bit and support a hell
of a lot of 64bit mode to get past the first few instructions in a
64bit kernel.

Certainly by the time userspace runs and syscalls happen, as seen by
the system_call_fastpath call, the cpu has clearly proven to handle
64bit mode. Even if it only lasted 4.7 seconds before crashing.
