Add slack to balloon driver to allow to counteract low-mem
address space allocations in backend drivers.
Signed-off-by: Keir Fraser <keir@xxxxxxxxxxxxx>

Could the 8M slack be made optional somehow? I like being able to have
16M domains...
The slack is in the p2m table, to balance out address space allocations by backend drivers. It's not intended that domains allocate an extra 8M beyond what the builder allowed them. I'll take a quick look.
