Hi Maciej, the send_IPI_self could be modified to send NMI (at moment it
uses self shortcut with fixed delivery mode). The question is rather if
we need it without a real caller yet. When Don's patch gets merged we
will have a real caller then and could update send_IPI_self to support
NMI delivery mode. Something like that :)
