The documentation and the commit message should probably make that first bit more explicit -- i.e. that /speculative/ accesses are indeed prevented.

Reading the commit message as it stands doesn't give any indication as to why E0PD would prevent Meltdown, as it only mentions constant-time faulting.

Speculative accesses aren't permitted to cause exceptions, so constant time or not to cause a 'level 0 fault' makes no difference.
