[PATCH] i386: Implement machine_emergency_reboot
set_cpus_allowed is not safe in interrupt context and disabling apics is complicated code so don't call machine_shutdown on i386 from emergency_restart(). Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
