Sure, I'll add something.

I tripped over this because I was accidentally trying to use a XenLinux
kernel as my crash kernel and it uses notes and hence suffers from the
bug. It won't affect a normal native kernel since they don't use notes.
I just figured I might as well fix it when I noticed it.

It does affect native kernels built from the xen-unstable source since
they (somehow) end up with an empty notes segment. Probably not worth
worrying about since it's probably a xen-unstable problem but it's
possible that the pv_ops xen stuff might do the same thing.
