This series adds the Corrected Machine Check Interrupt (CMCI) and
Uncorrectable Error No Action required (UCNA) emulation to KVM. The
former is implemented as a LVT CMCI vector. The emulation of UCNA share
the MCE emulation infrastructure.
This is the first of 3 patches that clean up KVM APIC LVT logic.
