I met several cases that die() is interrupted once irq is unlocked, on our platform which has multiple cpus, and enables panic_on_oops. It deadlock in some schedule related code, and hard-lockup is triggered. So the first criminal field is gone.
So I want to protect the whole flow of die() from irq, and let the panic flow execute correctly. Not sure this patch is suitable or there is better way to solve it. Please help to give some comments.
