64-bit PV and Meltdown

[marcotte%panix.com@localhost (Brian Marcotte)]

This question is specific to Meltdown.

XSA-254 states that when using the Xen PTI patches a 64-bit PV guest
is automatically protected against Meltdown even if the guest hasn't
been updated with a Meltdown mitigation.

Can anyone confirm this is the case with a NetBSD guest (64-bit PV)?

Thanks.
