Paolo Bonzini 6441fa6178 KVM: x86: avoid incorrect writes to host MSR_IA32_SPEC_CTRL ... If the guest is configured to have SPEC_CTRL but the host does not (which is a nonsensical configuration but these are not explicitly forbidden) then a host-initiated MSR write can write vmx->spec_ctrl (respectively svm->spec_ctrl) and trigger a #GP when KVM tries to restore the host value of the MSR. Add a more comprehensive check for valid bits of SPEC_CTRL, covering host CPUID flags and, since we are at it and it is more correct that way, guest CPUID flags too. For AMD, remove the unnecessary is_guest_mode check around setting the MSR interception bitmap, so that the code looks the same as for Intel.
