Subject: [Patch V2 0/3] x86, mce: Local Machine Check Exception (LMCE)

Hi Boris

Thanks for the feedback on V1. Almost all of your recommendations are
included in this update.

I haven't got a chance to test on qemu yet, but this patch fixes access to
MSR per your recommandation, so should be fine. I'm in process of making
similar changes to kvm/Qemu that i will send once I have learned to build
test it :-).

Historically machine checks on Intel X86 processors have been broadcast to all
logical processors in the system. Upcoming CPUs will support an opt-in
mechanism to request some machine checks delivered to a single logical
processor experiencing the fault.

For more details see Vol3, Chapter 15, Machine Check Architecture.

Modified to incorporate feedback from Boris on V1 patches.

  x86, mce: Add infrastructure required to support LMCE
