in the process make m5_exit more generic
arch/alpha/ev5.cc:
arch/alpha/ev5.hh:
There's no reason that this needs to be in an arch specific file
arch/alpha/isa_desc:
m5_exit -> SimExit
Emulate callpal halt and cause the simulator to exit
while we're at it, sort #includes
sim/sim_events.cc:
sim/sim_events.hh:
move the m5_exit function here, renaming it to SimExit.
Also Allow the caller to pass in the termination message.
