    x86: call machine_shutdown and stop all CPUs in native_machine_halt · d3ec5cae

    Impact: really halt all CPUs on halt
    Function machine_halt (resp. native_machine_halt) is empty for x86
    architectures. When command 'halt -f' is invoked, the message "System
    halted." is displayed but this is not really true because all CPUs are
    still running.
    There are also similar inconsistencies for other arches (some uses
    power-off for halt or forever-loop with IRQs enabled/disabled).
    IMO there should be used the same approach for all architectures OR
    what does the message "System halted" really mean?
    This patch fixes it for x86.
