Out-by-one error here... Fixed it for you, plus a couple of others.

I've applied the patches, but made one minor-but-invasive change: I didn't 
want to ask you to spin the patches again!

I changed "vcpu" to "cpu" everywhere (the v is pretty redundant in this 
context), which cut about a dozen lines of code out (things now fitted 
again!).

I also changed "vcpu_id" to simply "id" and made it unsigned.  Do you plan for 
this to always be equal to the index in the vcpu array BTW?  If so, we can 
neaten vcpu_start (now lg_cpu_start)...

You can grab the latest now...

Thanks!
Rusty.
