has proven to have a good effect when entering KDB by using a NMI, but it completely violates all the good rules about interrupts disabled while holding a spinlock in other occasions. This can be the cause of deadlocks on events where a normal IPI_STOP is expected. * Adds an new IPI called IPI_STOP_HARD on all the supported architectures. This IPI is responsible for sending a stop message among CPUs using a privileged channel when disponible. In other cases it just does match a normal IPI_STOP. Right now the IPI_STOP_HARD functionality uses a NMI on ia32 and amd64 architectures, while on the other has a normal IPI_STOP effect. It is responsibility of maintainers to eventually implement an hard stop when necessary and possible. * Use the new IPI facility in order to implement a new userend SMP kernel function called stop_cpus_hard(). That is specular to stop_cpu() but it does use the privileged channel for the stopping facility. * Let KDB use the newly introduced function stop_cpus_hard() and leave stop_cpus() for all the other cases * Disable interrupts on CPU0 when starting the process of APs suspension. * Style cleanup and comments adding This patch should fix the reboot/shutdown deadlocks many users are constantly reporting on mailing lists. Please don't forget to update your config file with the STOP_NMI option removal Reviewed by: jhb Tested by: pho, bz, rink Approved by: re (kib)
