8d3031fa1bfcdc623934ec7b15889a3f49248552 memory: notify hypervisor of all eventfds during listener (de)registration
When a new listener for an address space is registered, the hypervisor must be
informed of all existing eventfds for that address space by calling
eventfd_add() for that listener. Similarly, when a listener is de-registered
from an address space, the hypervisor must be informed of all existing eventfds
for that address space with a call to eventfd_del().
Same is also true for coalesced io. Send coalesced io add/del listener
notifications if any flatrage for the address space registered with the
listener intersects with any coalesced io range.
