Daisuke,
Are you planning on making changes to the kexec tools to automate
the setting of disable_cpu_apic to the capture kernel? Or do you
know someone who is planning this?

Forget to attach the link of patch for cpu0 hotplug.

In this patchset, BSP is also called CPU0.

Hi,
I am reviewing this patchset, and found there's a cpu0 hotplug feature
posted by intel which we can borrow an idea from. In that implementation,
CPU0 is waken up by nmi not INIT to avoid the realmode bootstrap code
execution. I tried it by below patch which includes one line of change.

Or do you envision the setting of disable_cpu_apic being put
