On VMRUN emulation evaluate the virtual tlb_control only to match hw behaviour. Deal with l1 guests which use flush-by-asid w/o checking cpuid bits or fill tlb_control with random data. Signed-off-by: Christoph Egger <Christoph.Egger@xxxxxxx> P.S.: No, this patch does not implement flush-by-asid for nested virtualization. -- ---to satisfy European Law for business letters: Advanced Micro Devices GmbH Einsteinring 24, 85689 Dornach b.
