One of the dangers when switching from one kernel to another is what happens to all of the other cpus that were running in the crashed kernel. In an attempt to avoid that problem this patch adds a nmi handler and attempts to shoot down the other cpus by sending them non maskable interrupts. The code then waits for 1 second or until all known cpus have stopped running and then jumps from the running kernel that has crashed to the kernel in reserved memory. The kernel spin loop is used for the delay as that should behave continue to be safe even in after a crash.
