[Xen-devel] [PATCH v2 10/10] x86/cpuid: Enable CPUID Faulting for PV control domains by default

2019-09-13 Thread Andrew Cooper
The domain builder no longer uses local CPUID instructions for policy decisions. This resolves a key issue for PVH dom0's. However, as PV dom0's have never had faulting enforced, leave a command line option to restore the old behaviour. Advertise virtualised faulting support to control domains
