Hi,

Is there a way to figure out which (second stage) page size is being used for memory events?
I assume that it is 4K. There is a page_size field in struct vmi_instance but there is no way
to obtain it.

Xen only supports setting mem_access permissions on 4k granularity.
There is right now no API that would give you this information
separately. Probably once SPP becomes available we'll need to rethink
the API side for this.
