Don't use the superfluous shared page, return the event channel directly as part of the domctl struct, instead. In-tree consumers (xenpaging, xen-access) updated. This is an ABI/API change, so please voice any concerns. Known pending issues: - pager could die and its ring page could be used by some other process, yet Xen retains the mapping to it. - use a saner interface for the paging_load buffer. This change also affects the x86/mm bits in the hypervisor that process the mem_event setup domctl.
