Keith Owens 958b166c00 [IA64] Pass more data to the MCA/INIT notify_die hooks
The MCA/INIT handlers maintain important state in the SAL to OS (sos)
area and in the monarch_cpu flag.  Kernel debuggers (such as KDB) need
this data, and may need to adjust the monarch_cpu field so make the
data available to the notify_die hooks.  Define two more events for
calling the functions on the notify_die chain.
