The patch titled Subject: kernel/sys.c: call disable_nonboot_cpus() in kernel_restart() has been removed from the -mm tree. Its filename was kernel-sysc-call-disable_nonboot_cpus-in-kernel_restart.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Shawn Guo <shawn.guo@xxxxxxxxxx> Subject: kernel/sys.c: call disable_nonboot_cpus() in kernel_restart() As kernel_power_off() calls disable_nonboot_cpus(), we may also want to have kernel_restart() call disable_nonboot_cpus(). Doing so can help machines that require boot cpu be the last alive cpu during reboot to survive with kernel restart. This fixes one reboot issue seen on imx6q (Cortex-A9 Quad). The machine requires that the restart routine be run on the primary cpu rather than secondary ones. Otherwise, the secondary core running the restart routine will fail to come to online after reboot.
