[Xen-devel] [PATCH] nestedsvm: fix tlb_control

[Christoph Egger <Christoph.Egger@xxxxxxx>]

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.
