KVM: SVM: Add new intercept word in vmcb_control_area
The new intercept bits have been added in vmcb control area to support
few more interceptions. Here are the some of them.
- INTERCEPT_INVLPGB,
- INTERCEPT_INVLPGB_ILLEGAL,
- INTERCEPT_INVPCID,
- INTERCEPT_MCOMMIT,
- INTERCEPT_TLBSYNC,
Add a new intercept word in vmcb_control_area to support these instructions.
Also update kvm_nested_vmrun trace function to support the new addition.
AMD documentation for these instructions is available at "AMD64
Architecture Programmer’s Manual Volume 2: System Programming, Pub. 24593
Rev. 3.34(or later)"
The documentation can be obtained at the links below:
