The combination of a newer kernel and newer qemu make qemu work with
-smp 2 . Rather than go figure out what got fixed let's just be happy
it did.

Title:
arm64: -smp 2 hangs qemu
Status in QEMU:
New
Public bug reported:
It appears that smp is broken on qemu for arm64. I'm looking into the
root cause but am curious if others can reproduce in their environments.
Tested with commit f368c33d5ab09dd5656924185cd975b11838cd25 (July 22)

Yea it's not hard to invent a random format each time we write something
on disk.
But I think ASN.1 BER will be useful to have in qemu anyway. E.g. it's a
better format for migration than what we have now. Once we have it in
tree re-using it seems cleaner than maintaining some per-TPM thing.
