This is changing the vararg from int to unsigned long. I have no
insights yet on how this is handled and whether that is okay; I would at
least expect this change to be mentioned in the commit message.

Minor nit: If you change this to CPUState *cs you spare the renaming in
05/12. Alternatively use x86_cpu there (not much code affected so you
can just ignore this, no need to respin just for that).
Otherwise looks okay to me.
