That is how it is done in ia64. The MCA interrupt
handler does the low level handling. It makes sure
all the cpus have rendezvoused, looks at the MCA record
to determine what happend and does whatever recovery
steps are needed, such as kill the application.
It definitely needs to be handled in the kernel.
