[PATCH v1] Add KVM support for Intel local MCE

[Haozhong Zhang]

Previous v0 patch can be found at
http://permalink.gmane.org/gmane.linux.kernel/2104347

Changes in v1:
 * Change macro KVM_MCE_CAP_SUPPORTED to variable kvm_mce_cap_supported.
 * Include LMCE capability in kvm_mce_cap_supported only on Intel CPU,
   i.e. LMCE can be enabled only on Intel CPU.
 * Check if LMCE is enabled in guest MSR_IA32_FEATURE_CONTROL when
   handling guest access to MSR_IA32_MCG_EXT_CTL.

This patch along with the corresponding QEMU patch series (sent via
another email with title "[PATCH v3 0/2] Add QEMU support for Intel
local MCE") enables Intel local MCE feature for guest. This KVM patch
handles guest access to LMCE-related MSR (MSR_IA32_MCG_EXT_CTL and
MSR_IA32_FEATURE_CONTROL).
