[PATCH 0/5] x86, NMI: give NMI handler a face-lift

Restructuring the nmi handler to be more readable and simpler.

This is just laying the ground work for future improvements in this area.

I know people were complaining about having DIE_NMI and DIE_NMI_IPI, but
for now it is consistent with what was there before. Hopefully, we can
modify the notifier chain to make it smarter and combine the two events.

I also left out one of Huang's patch until we figure out how we are going
to proceed with a new notifier.

Tested 32-bit and 64-bit on AMD and Intel machines.

Cheers,
Don
