Holding the p2m lock while calling ept_sync_domain() is very expensive
since it does a on_selected_cpus() call. IPIs on many socket machines
can be very slows and on_selected_cpus() is serialized.

If a guest allocates a page and the tlbflush_timestamp on the page
indicates that a TLB flush of the previous owner is required, only the
linear and combined mappings are invalidated. The guest-physical
mappings are not invalidated.
This is currently safe because the EPT code ensures that the

This series improves the performance of EPT by further reducing the
impact of the translation invalidations (ept_sync_domain()). By:
a) Deferring invalidations until the p2m write lock is released.
Prior to this change a 16 VCPU guest could not be successfully

Can you add a brief description about why these are being moved? Then,

As said before, dependencies on prompt-less options are bogus
and potentially confusing (and really wrong here - there's nothing
