Add MCE simulation support to qemu/kvm
KVM ioctls are used to initialize MCE simulation and inject MCE. The
real MCE simulation is implemented in Linux kernel. The Kernel part
has been merged.
ChangeLog:
v7:
- Re-based on qemu-kvm.git/next branch
v6:
- Re-based on latest qemu-kvm.git
v5:
- Re-based on latest qemu-kvm.git
v3:
- Re-based on qemu/tcg MCE support patch
v2:
- Use new kernel MCE capability exportion interface.
