The idea is to have a more robust and reliable way to stop cpus when serializing things like the panic path. More details in the changelogs. Don Zickus (3): x86, reboot: Use NMI instead of REBOOT_VECTOR to stop cpus x86, NMI: Add NMI IPI selftest x86, NMI: knob to disable using NMI IPIs to stop cpus Documentation/kernel-parameters.txt | 4 ++ arch/x86/Kconfig.debug | 12 ++++++ arch/x86/include/asm/smp.h | 1 + arch/x86/kernel/smp.c | 71 ++++++++++++++++++++++++++++++++++- arch/x86/kernel/smpboot.c | 57 ++++++++++++++++++++++++++++ 5 files changed, 143 insertions(+), 2 deletions(-) -- 1.7.6.4
