I chose XEN_PAGE_SIZE because the hypercall will eventually copy in the buffer so it seemed like a reasonable value to use. If you want to just use 4096 then I am ok with that.
PS: If you want to change from XEN_PAGE_SIZE to 4096 then I assume you are happy to do this at commit and don't need me to send a v4?
