KVM: SVM: Adding support for configuring x2APIC MSRs interception

Browse source

When enabling x2APIC virtualization (x2AVIC), the interception of
x2APIC MSRs must be disabled to let the hardware virtualize guest
MSR accesses.

Current implementation keeps track of list of MSR interception state
in the svm_direct_access_msrs array. Therefore, extends the array to
include x2APIC MSRs.
