    Add common orderly_poweroff() · 10a0a8d4
    Jeremy Fitzhardinge authored
    Various pieces of code around the kernel want to be able to trigger an
    orderly poweroff.  This pulls them together into a single
    implementation.
    
    By default the poweroff command is /sbin/poweroff, but it can be set
    via sysctl: kernel/poweroff_cmd.  This is split at whitespace, so it
    can include command-line arguments.
    
    This patch replaces four other instances of invoking either "poweroff"
    or "shutdown -h now": two sbus drivers, and acpi thermal
    management.
    
    sparc64 has its own "powerd"; still need to determine whether it should
    be replaced by orderly_poweroff().
