When enabled, two extra VMCS fields are used: SPEC_CTRL mask and shadow. Bits set in mask are not allowed to be toggled by the guest (either set or clear) and the value in the shadow field is the value the guest expects to be in the SPEC_CTRL register. By using it the hypervisor can force the value of SPEC_CTRL bits behind the guest back without having to trap all accesses to SPEC_CTRL, note that no bits are forced into the guest as part of this patch. It also allows getting rid of SPEC_CTRL in the guest MSR load list, since the value in the shadow field will be loaded by the hardware on vmentry.

When enabled, two extra VMCS fields are used: SPEC_CTRL mask and shadow. Bits set in mask are not allowed to be toggled by the guest (either set or clear) and the value in the shadow field is the value the guest expects to be in the SPEC_CTRL register. By using it the hypervisor can force the value of SPEC_CTRL bits behind the guest back without having to trap all accesses to SPEC_CTRL, note that no bits are forced into the guest as part of this patch. It also allows getting rid of SPEC_CTRL in the guest MSR load list, since the value in the shadow field will be loaded by the hardware on vmentry.
